Learning the friendly way

Looking for your IBAN number to complete an international payment? You’re not alone. Whether you’re sending money abroad, receiving funds from Europe, or setting up a business payment, finding an IBAN can be confusing, especially if you’re based in the United States.

The good news is that your IBAN is usually easy to find once you know where to look. In most cases, it’s available through your online banking portal, mobile banking app, or bank statements.

So, let's dive in and learn exactly what an IBAN number is, whether you actually need one, how to find it step by step, and how it differs from SWIFT codes and routing numbers. By the end, you’ll know exactly what information to provide, and where to find it, so your international transfer goes through smoothly.

What is an IBAN number?

An IBAN, or International Bank Account Number, is a standardized format used to identify bank accounts across borders. Think of it as an internationally recognized address for a specific bank account, designed to make global payments faster, safer, and less error-prone.

IBANs were introduced in Europe to simplify cross-border financial transactions and are now used by 89 countries, primarily across Europe, the Middle East, and parts of Africa. The system reduces payment errors by validating account details before a transfer is processed.

It’s important to understand one key point:
Banks in the United States do not use IBAN numbers.

Instead, US banks rely on:

• Routing numbers for domestic payments
  
  
• SWIFT/BIC codes for international wire transfers

If you’re a US customer sending money to an IBAN country (like Germany, France, or the UK), you’ll need the recipient’s IBAN, not your own. If you’re receiving money from abroad, you’ll provide your routing number, SWIFT code, and account number instead.

What does an IBAN number look like?

An IBAN number is an alphanumeric code of up to 34 characters. Not to be mistaken for a bank account number, an IBAN typically includes the account number along with several other identifying codes. These include codes that identify the bank the funds are being sent to and the country. So what does an IBAN number look like?

An International Bank Account Number will always include:

• A two-letter code identifying the country
• Two check digits
• The bank code
• A code of up to 30 characters is known as the Basic Bank Account Number (BBAN) which is decided on by the country and is used as a national standard for domestic payments.

For example, a UK IBAN number will have the following format:

GB28VBCD12345612345678

GB represents the country code

28 represents the check digits

VBCD represents the bank code

123456 represents the sort code

And the next 12345678 represents the account number. 

SWIFT codes vs IBAN numbers

You might be wondering at this stage what the difference is between a SWIFT code and an IBAN number. Let’s explore the difference below.

A SWIFT code (Society for Worldwide Interbank Financial Telecommunication), also known as a Bank Identifier Code (BIC), is a unique identification bank code used to identify the specific financial institution in international wire transfers. SWIFT codes consist of either 8 or 11 characters and include information about the bank and its location.

An IBAN (International Bank Account Number), on the other hand, is a standardized international numbering system used to identify bank accounts for international money transfers. As covered above, it typically consists of a country code, two check digits, and a BBAN. The purpose of the IBAN number is to help ensure that international payments are processed accurately and efficiently.

In summary, a SWIFT code is used to identify a specific bank or financial institution in international wire transfers. An IBAN number is used to identify a specific bank account in cross-border transactions.

Both codes are important for international money transfer and are used in conjunction with each other to ensure that funds are transferred to the correct account at the correct institution.

Which countries and banks use IBAN numbers?

Countries That Use IBANs

• All EU & SEPA Members: e.g., France, Germany, Spain, Italy
  
  
• Non-EU European States: United Kingdom, Switzerland, Norway, Iceland
  
  
• Middle East: Saudi Arabia, UAE, Qatar, Kuwait
  
  

Countries That Do NOT Use IBANs

• United States (routing + SWIFT)
  
  
• Canada (institution + transit numbers)
  
  
• Australia (BSB codes)
  
  
• China, Japan, India
  
  

Major US Banks

Chase, Bank of America, Wells Fargo, Citi, and similar institutions do not issue IBANs. For incoming international payments, they provide a SWIFT code (for example, CHASUS33 for Chase), along with your routing and account numbers.

How to find your IBAN number

To find your IBAN number, you will need to check your bank statements, online banking portal, or contact your bank directly. The exact process for finding your IBAN number may vary depending on the country and financial institution, but here are some general steps you can follow:

Check your bank statement: Your IBAN number should be listed on your bank account statement, which you can access online or receive in the mail.

Check your online banking portal: If you use online banking, you can usually find your IBAN number by logging into your account and navigating to your account details or settings.

Contact your bank: If you cannot find your IBAN number through the above methods, you can contact your bank directly and ask them to provide it for you. Be prepared to provide your account number and other identifying information.

It's important to note that not all countries use an IBAN number, so if you are sending or receiving an international payment, you may need to use a different format for bank account identification.

Additionally, IBAN numbers can vary in length and format depending on the country and financial institution. Before you transfer money or make an international transaction always check what information is required and whether it is accurately inputted.

Tap’s business account and IBANs

When creating a business account on the Tap network, users will automatically gain access to their own IBAN number which can be used to receive international payments. With several currency options, the account caters to a wide range of industries and services.

Three cards. Three paths. One goal. Today, if you need to handle payments, you have more options than ever before. Debit cards, credit cards, and prepaid cards are all widely used for everyday spending, online shopping, travel, payroll, and digital payments. While they can look similar and may carry logos from Mastercard or Visa, the way each card handles money, fees, risk, and consumer protection is fundamentally different.

Understanding these differences matters for budgeting, personal finance, decision-making, and security. Whether you are a consumer managing everyday life or a business evaluating card products for customers, knowing how each card type works helps ensure the right fit for specific needs, regulations, and usage scenarios.

So, jump in! Let’s break down how debit, credit, and prepaid cards work, and how they compare!

Quick Comparison Overview

Simply put, the main difference comes down to where the money comes from and when payment happens.

• Debit card: Uses money directly from a linked bank account or deposit account. Payments are deducted immediately.
• Credit card: Uses borrowed money provided by an issuing bank. Payments are settled later, often with interest if not repaid in full.
• Prepaid card: Uses money loaded in advance. Not typically linked to a bank account and cannot exceed the preloaded balance.

Debit and prepaid cards help control spending by limiting access to available funds. Credit cards introduce deferral, interest, and credit risk but offer stronger consumer protection and rewards. These differences affect fees, acceptance, regulation, and suitability for different consumers and businesses.

What Is a Debit Card and How Does It Work?

A debit card is directly linked to a bank account or credit union account. When a consumer makes a financial transaction, the funds are withdrawn from their deposit account almost instantly and reflected on their bank statement.

Debit cards are commonly used for everyday purchases, ATM withdrawals via an automated teller machine, bill payments, and point-of-sale transactions. Some retailers allow cash back at checkout, making debit cards a practical alternative to cash.

Key characteristics of debit cards include:

• Access to money you already have on deposit
• No interest or annual percentage rate
• Wide acceptance in retail, e-commerce, and mobile app environments
• Optional overdraft features, often with a fee

From a limitation perspective, debit cards do not help build a credit score and may offer less protection than credit cards in cases of theft or fraud. Since transactions impact the bank account immediately, compromised personal data can affect liquidity until disputes are resolved.

What Is a Credit Card and How Does It Work?

A credit card allows consumers to borrow money from an issuing bank up to an approved credit limit. Each purchase creates a loan that must be repaid according to the card’s terms. If the balance is not paid in full by the due date, interest is charged based on the card’s annual percentage rate.

Credit cards operate on a billing cycle rather than instant settlement. This deferral makes them useful for large purchases, travel, online shopping, and expense management.

Core features of credit cards include:

• Credit checks and approval requirements
• Monthly statements and repayment schedules
• Interest charges, fees, and fine print
• Strong consumer protection and dispute rights

Credit cards can build credit history and support loyalty programs, cashback websites, and incentives. However, they also introduce credit risk, potential debt accumulation, and higher costs if balances are carried long term.

What Is a Prepaid Card and How Does It Work?

A prepaid card is funded with money loaded in advance and is not usually linked to a traditional bank account. Once the balance reaches zero, the card cannot be used unless additional funds are deposited. This structure makes prepaid cards a controlled payment tool rather than a credit product.

Funds can typically be loaded through direct deposit (such as payroll or tax refunds), bank transfers, cash loads at retailers, or digital wallets like PayPal. Many prepaid cards are issued on major networks, enabling broad acceptance for purchasing and e-commerce payment systems.

Common prepaid card types include:

• Reloadable prepaid cards
• Gift cards and promotional merchandise cards
• Payroll cards
• Government benefit cards

Addressing common questions: prepaid cards can usually be used at ATMs, though fees vary by provider. Funds do not expire if the card is replaced. Visa and MasterCard branded prepaid cards often support chargebacks, though protections may be more limited than credit cards. Acceptance issues can occur with hotels, car rentals, or merchants requiring advance payment holds.

Prepaid cards are popular for budgeting, gifting, controlled spending for students or dependents, and use cases where a bank account or credit check is not desirable.

Debit Card vs. Credit Card: Key Differences

The primary distinction between debit and credit cards is ownership of funds. Debit cards use the consumer’s own money, while credit cards use borrowed capital.

Debit card payments are immediate and tied to account balances. Credit card payments are deferred and settled later. Debit cards avoid interest but do not build credit. Credit cards can improve a credit score but introduce interest, fees, and liability if mismanaged.

Debit cards are often preferred for daily spending, budgeting, and ATM access. Credit cards are better suited for travel, higher-value purchases, online shopping, and situations requiring stronger consumer protection.

Prepaid Card vs. Debit Card: Key Differences

Prepaid cards and debit cards are often confused because both limit spending to available funds. The critical difference is the bank account requirement.

Debit cards require a bank or credit union account and provide direct access to deposits. Prepaid cards operate independently and require funds to be loaded first. Prepaid cards typically do not allow overdrafts, making them more restrictive but easier to control.

Prepaid cards are frequently used for gifting, payroll distribution, and controlled spending. Debit cards are better suited for general-purpose banking and long-term financial management.

Prepaid Card vs. Credit Card: Key Differences

Prepaid cards and credit cards sit at opposite ends of the payment spectrum. Prepaid cards use preloaded money and do not require repayment. Credit cards use borrowed money and require monthly payments.

Prepaid cards do not impact credit scores and usually avoid interest. Credit cards require approval, involve interest, and contribute to credit history. Each serves a distinct role depending on the consumer’s financial situation, risk tolerance, and spending behavior.

Launching a card program is easier than ever. Today, thanks to modern technology, businesses can issue digital debit, credit cards or virtual cards faster than ever. The real challenge comes next: how do you turn a card program into a sustainable source of revenue?

Many card programs start with a strong focus on customer acquisition and distribution. Cards are issued, users sign up, and transactions begin to flow. But without a clear monetization strategy, growth alone rarely leads to profitability. Margins are thin, regulation limits certain fees, and relying on a single revenue stream is rarely enough.

Successful card programs approach monetization as a business model decision, not an afterthought. They understand how money moves through the payment ecosystem, which revenue streams are available to them, and how card usage behavior directly impacts results. So, dive in and learn how card programs generate revenue, why active usage matters more than total cards issued, and which monetization levers matter most in practice.

The Foundation: How Card Programs Generate Value

Before discussing monetization, it’s essential to understand how a card transaction actually works and where value is created. A typical card payment follows a familiar flow: the cardholder makes a purchase with a merchant using funds from their bank account, the merchant’s acquiring bank processes the transaction, the card network (such as Visa or Mastercard) routes it, and the issuing bank ultimately approves and settles the payment. Behind the scenes, multiple parties exchange data, manage financial risk, and move money.

From a revenue perspective, several fees are involved. Merchants pay a merchant service charge, which is split across the ecosystem. A portion goes to the card network as assessment fees, another to processors, and a key portion goes to the issuer as interchange revenue. Depending on your role in the value chain, your business may earn revenue directly as the issuer or indirectly through revenue sharing with an issuing bank or program manager. Ultimately, your program structure determines which monetization options are available and how scalable they are.

Why Active Cardholders Drive Monetization

One of the most common mistakes in card programs is focusing on the total number of cards issued rather than how often those cards are actually used. There is a critical difference between issued cards, activated cards, and active cardholders. An issued card that sits unused generates no interchange, no FX revenue, and no long-term value. In contrast, a smaller base of highly active users can outperform a much larger but disengaged audience.

Active usage directly impacts every meaningful metric: transaction volume, revenue per user, retention, and customer lifetime value. This is why successful programs aim to become a user’s top-of-wallet choice, not just a backup payment method. Features like real-time notifications, budgeting tools, mobile app usability, loyalty incentives, and seamless acceptance all contribute to habitual usage.

For example, 500 cardholders making frequent purchases often generate more gross income than 2,000 cardholders who only transact once a month. Monetization scales with engagement, not vanity metrics. Any sustainable revenue model must therefore start with a clear plan for activation, retention, and ongoing card usage.

Five Core Revenue Streams for Card Programs

Most profitable card programs rely on multiple layered revenue streams rather than a single source. Below are the five most important ones.

1. Interchange Fees: The Core Revenue Stream

Interchange is the fee paid by the acquiring bank to the issuing bank for each card transaction. It is typically calculated as a percentage of the transaction value, sometimes combined with a fixed fee. Interchange rates vary based on card type, region, merchant category, and whether the payment is card-present or online.

Regulation plays a major role. In the United States, for instance, debit interchange is capped for large banks under the Durbin Amendment, while credit card interchange remains largely uncapped. In Europe, interchange caps are stricter across both debit and credit cards. Commercial and business cards often command higher interchange but require different distribution strategies.

While interchange is foundational, it is rarely sufficient on its own. Operating costs, fraud management, compliance, and customer support quickly erode margins. Modern card programs treat interchange as a baseline, not the entire business case.

2. Subscription and Membership Fees

Many programs introduce monthly or annual fees tied to premium features. These may include higher spending limits, enhanced customer service, insurance benefits, advanced expense management, or exclusive rewards.

Subscription revenue offers predictability and improves cash flow, but it only works when the value proposition is clear and the pricing game is played smartly. Consumers and businesses are increasingly sensitive to pricing, and poorly justified fees can increase churn. Tiered pricing models are often more effective, allowing users to choose a plan aligned with their needs.

3. Foreign Exchange (FX) Revenue

FX revenue is generated when cardholders spend in a foreign currency. Issuers may apply a markup to the network exchange rate or share in FX margins with partners. This model is particularly relevant for travel, cross-border commerce, and international users.

However, competition has intensified. Transparency requirements and “zero FX fee” positioning have reduced margins. FX revenue tends to be meaningful only at scale or when international usage is central to the product experience.

4. Interest and Financing (Credit Programs Only)

For credit card programs, interest income from revolving balances and installment plans can be a significant revenue stream. Annual percentage rates (APR), deferred payments, and buy-now-pay-later structures fall into this category.

This model requires robust risk management, regulatory compliance, and access to capital. It is not applicable to debit or prepaid programs but can dramatically change unit economics when executed responsibly.

5. Card Network Incentives

Visa, MasterCard, and American Express offer incentive programs to encourage issuance, usage, and international acceptance. These incentives may be volume-based, activity-based, or tied to specific launch milestones.

While often overlooked, network incentives can meaningfully offset early costs for growing programs. Negotiation, reporting accuracy, and long-term partnership strategy all influence how much value a program captures here.

The Three Pillars of a Monetizable Card Program

Revenue streams only work when supported by a strong product strategy. In practice, successful programs are built on three pillars.

First, they solve a real problem. This may involve simplifying payments, improving expense control, increasing acceptance, or offering better visibility into spending. Cards that exist without a clear use case struggle to drive consistent transactions.

Second, they deliver perceived value, not just functional utility. Trust, brand, personalization, and incentives all influence whether a user chooses one card over another. Emotional factors often determine top-of-wallet status.

Third, they target the right audience from day one. Consumer cards, business cards, travel cards, and industry-specific programs all monetize differently. Product-market fit determines which revenue streams are viable and how quickly they scale.

By understanding card economics, prioritizing active usage, and layering multiple revenue streams, businesses can build card programs that generate real, sustainable value. From here, the next step is execution: choosing the right partners to turn strategy into results.

Imagine a world where email providers couldn’t communicate. Gmail users couldn’t message Outlook users, and Yahoo Mail existed in complete isolation. This is essentially the state of today’s blockchain ecosystem: fragmented networks operating in silos, unable to share data or value efficiently. This is where Quant Network comes in.

Made up of the Overledger blockchain operating system and QNT token, the goal of the Quant Network is to allow multiple blockchains to work together and to give more flexibility when it comes to linking different global networks, services, and chains. With an impressive founder and resilience to the bear market, QNT has made a considerable impression in the industry.

What Is The Quant Network?

The Quant Network was designed to connect blockchains and networks on a global scale, prioritising interoperability and trust functions between them using the Overledger operating system, the first OS built for blockchains.

The Overledger network acts as the backbone of the project and is not a blockchain but rather an Application Programming Interface (API) gateway that allows developers to build decentralised multi-chain applications (known as Mapps) and bridges the gap between various blockchain networks.

The Quant project believes that this technology will be the foundation on which the future digital economy will be built. In light of this, the network has been working with central banks in the US and UK to build Central Bank Digital Currencies (CDBCs).

Founded in 2015 the platform officially launched in 2018 following a successful ICO earlier that year. July 2020 marks the launch of the world’s first blockchain operating system in July 2020, Version 1.0.

Who Created The Quant Network?

Quant was founded by Gilbert Verdian, a cybersecurity expert who has held government-level positions around the world. These positions include the UK Treasury, the Australian Department of Health, and the US Federal Reserve, and private sector roles at HSBC Bank, Mastercard’s Vocalink, BP, and more.

With over two decades of experience in the cybersecurity space, Verdian learned the power that blockchain technology holds when it comes to solving a plethora of security problems related to the exchange of digital assets and information on a global level. 

Verdian sits as the chair of the UK Blockchain and Distributed Ledger Technology committee and is a member of the EU’s Blockchain Observatory and the Federal Reserve. 

In 2017, Colin Paterson and Paolo Tasca joined the project as co-founders, each bringing their own impressive experience. Paterson, acting Chief Technology Officer, is a cybersecurity expert having worked with Deutsche Bank and Vocalink and acted as the chief information officer of NSW Ambulance, the CISO of eHealth NSW, and the security lead of the Ministry of Justice, UK, prior to joining the project. 

Tasca, Chief Strategist, serves as the Executive Director of the University College London (UCL) Centre for Blockchain Technologies, Executive Board Member of the DEC Institute, and as Co-Chair of the Hedera Treasury Management and Token Economics Committee.

How Does The Quant Network Work?

The Overledger Operating System

Quant’s technology revolves around Overledger, which functions as a distributed ledger gateway rather than another blockchain. This distinction is key: Overledger doesn’t process transactions itself but rather facilitates communication between different blockchains that do. The system uses a four-layer architecture:

1. Transaction Layer: This foundational layer connects to various blockchains like Bitcoin, Ethereum, Ripple, Hyperledger Fabric, and R3 Corda. It reads and writes transactions across these different ledgers without interfering with their native operations.
2. Messaging Layer: Acting as the communication hub, this layer verifies, orders, and shares transaction data between connected blockchains. It ensures that information moving between networks maintains integrity and security.
3. Filtering & Ordering Layer: This layer validates off-chain messages and filters out data so that only relevant information reaches the application.
4. Application Layer: Here, developers build multi-chain decentralized applications (called Mapps or mDapps) that can operate across multiple blockchains simultaneously. This layer provides APIs and interfaces that simplify cross-chain development.

Multi-Chain Applications (Mapps)

Traditional dApps run on a single platform (like Ethereum or Polkadot), limiting their utility and user base. Mapps break these barriers.

For example, a Mapp could use Bitcoin for value storage, Ethereum for smart contract execution, and Hyperledger for regulated transaction records, all within a single application. This flexibility allows businesses to choose the best blockchain for each specific function rather than compromising with a one-size-fits-all solution.

APIs and Development

Quant prioritizes usability for enterprise adoption. The platform offers standardized APIs that allow developers to connect existing business processes and infrastructure to multiple blockchains with minimal coding. The drag-and-drop interface for creating smart contracts and tokens (using Quant’s QRC-20 standard, similar to Ethereum’s ERC-20) means even teams with limited blockchain experience can operate across multiple chains.

This approach significantly reduces the cost and time required to implement blockchain technology, addressing what has been a major obstacle.

What Makes Quant Different?

Blockchain Agnosticism

Overledger connects a wide array of public and private blockchains through a single API, without requiring them to adopt new protocols or compromise their security models. This feature is particularly valuable for financial institutions and corporations with existing blockchain investments.

Business-First Design

Quant was built from the ground up for enterprise adoption, with features addressing business needs: regulatory compliance, data security, integration with legacy systems, and scalability on a global scale. The team’s background in financial services and government projects informs these design choices.

Production-Ready Technology

While many interoperability projects remain in development, Quant’s technology is already deployed in production environments. Partnerships with central banks, healthcare sector organizations, and financial institutions demonstrate real-world utility beyond theoretical innovation.

Patent-Protected Innovation

Quant holds multiple patents for its Overledger technology, providing intellectual property protection and potential competitive barriers. This factor may appeal to institutional investors concerned about sustainable competitive advantages.

What Is QNT?

QNT is an ERC-20 token that is used to access the Overledger network and validate transactions on the network. There is a maximum supply of 14.88 million QNT tokens, of which over 81% are in circulation, at the time of writing.

All product users, developers, and gateway operators are required to purchase annual licences, used to maintain platform efficiency. These licence fees are converted to QNT and locked up in the Quant treasury. If a user does not renew their licence, they forfeit their fees, discouraging them from dumping tokens on the market if the price increases.

Transaction fees for using Overledger are paid in QNT to gateway operators. Since its launch in August 2018, QNT has seen consistent price growth and activity on the network.

Where Can I Get QNT?

You can trade QNT on the Tap app, one of the most secure solutions in the crypto space as being a fully regulated crypto fintech. Using a range of cryptocurrencies and fiat currencies on offer, users can exchange any of the supported currencies to build a healthy portfolio that can be safely stored in its unique wallet linked to your account.

Ever sent ETH and wondered where it went? Interacted with a smart contract and want to verify if it worked? This is where Etherscan comes in.

Etherscan is the most widely used tool for exploring and verifying activity on the Ethereum blockchain. It allows you to track financial transactions, inspect smart contracts, monitor wallets, and analyze on-chain data in real time, all through a simple web page.

In a decentralized system where no single organization controls the ledger, a tool like Etherscan plays a critical role in transparency, trust, and verification. Instead of relying on intermediaries, you can independently confirm payments, balances, contract interactions, and network fees.

So, join us. We’ll learn what Etherscan is, how it works, and how to use it step by step. By the end, you’ll be able to navigate Ethereum data confidently, whether you’re a complete newbie, an investor, or simply curious about Web3.

What Is Etherscan?

Etherscan is a blockchain explorer and analytics platform built specifically for the Ethereum network. Its primary function is to retrieve, organize, and display public blockchain data in a way that end users can easily understand and verify.

Think of Etherscan as a search engine for Ethereum. Instead of indexing web content on the internet like Google, it indexes blockchain data such as transaction records, wallet balances, smart contracts, tokens, and non-fungible tokens. Every action recorded on Ethereum’s distributed ledger can be searched, viewed, and validated through Etherscan.

A common misconception is that Etherscan is a wallet or a payment service. It is not. Etherscan does not store cryptocurrency, manage private keys, process payments, or execute trades. It is strictly a read-only interface that displays information already stored on the blockchain.

The platform was founded by Matthew Tan and is headquartered in Kuala Lumpur, Malaysia. Over time, it has become the most trusted and widely used Ethereum block explorer due to its accuracy, speed, usability, and depth of data.

Etherscan is free to use and does not require account creation for basic features. Advanced users, developers, and programmers can optionally access APIs, notification systems, and analytics tools.

What Is a Block Explorer?

A block explorer is application software that visualizes blockchain data. Because blockchains are decentralized and lack a central dashboard, explorers act as the main interface between raw blockchain data and human users.

In simple terms, a block explorer is like Google for blockchains. Instead of searching articles or websites, you search transaction hashes, wallet addresses, blocks, or smart contracts. The software retrieves this information from the network and presents it in a structured, point-and-click format.

Every major blockchain, including Ethereum and Bitcoin, has one or more block explorers. Without them, verifying transactions, analyzing market activity, or learning how blockchain technology works would be significantly more difficult.

How Does Etherscan Work?

Etherscan operates through a three-step technical process, simplified for accessibility.

First, data retrieval. Etherscan connects to Ethereum nodes using remote procedure calls and communication protocols. These nodes maintain copies of the blockchain ledger and continuously update with new blocks and transactions through peer-to-peer networking.

Second, data organization. All retrieved transaction data, contract interactions, token transfers, and balance changes are indexed into a structured database. This allows fast information retrieval, statistical analysis, and historical tracking across millions of records.

Third, data presentation. Etherscan displays this information through a clean user interface optimized for web browsers and mobile devices. Tables, charts, timestamps, calendar dates, and analytics tools help users interpret complex data accurately.

Importantly, Etherscan does not control Ethereum or any other cryptocurrency, validate transactions, or influence mining. It simply reads the ledger and presents it in near real-time. No permission, consent, or account is required to view public data.

What Can You Do With Etherscan?

Track Ethereum Transactions

Every Ethereum payment generates a unique transaction hash, also known as a TXID. By pasting this identifier into Etherscan, you can track the transaction’s status, confirmations, value, gas fee, and timestamp.

This is especially useful for verifying payments, checking failed transactions, monitoring settlement speed, and confirming whether funds were successfully transferred.

Monitor Wallet Addresses

Etherscan allows you to analyze any public wallet address. You can view ETH balances, transaction history, token holdings, NFT assets, and incoming or outgoing payments.

This feature is commonly used for portfolio tracking, investment research, surveillance of large holders, and due diligence on projects and organizations.

Explore Smart Contracts

Smart contracts power decentralized applications, decentralized finance platforms, swaps, and tokenization systems. Etherscan lets you inspect verified contract code, view functions, validate creators, and analyze contract interactions.

For developers and advanced users, this helps with verification, debugging, and understanding how application software behaves on-chain.

Check Gas Prices

Ethereum uses gas fees to process transactions. Etherscan’s gas tracker shows real-time gas prices, historical averages, and estimated costs using weighted arithmetic mean calculations.

This helps users time transactions during periods of lower network congestion, reducing costs.

Analyze Tokens and NFTs

Etherscan provides detailed data on ERC-20 tokens and non-fungible tokens. You can view market value, supply and demand metrics, transfer statistics, holder distribution, and contract details.

How To Find A Transaction On Etherscan

Understanding how to track your transactions can be a powerful tool in the world of cryptocurrency, from seeing how many confirmations it has gone through to the amount of gas fees paid. 

Each transaction on the blockchain is given a transaction ID (TXID) or transaction hash which identifies the specific transaction (similar to a person's identity number). It looks something like this: 

0x3349ea4144aed83291f87b3904b02f8f1e76c3b5bfed0d95a000fafddaed01bc

In order to get the real-time updates on a transaction, you will need to enter this TXID into the space provided on the Etherscan website.

Etherscan is completely free to use. You do not pay to search transactions, view wallet balances, or analyze blockchain data. No subscription or account is required for core features.

However, if you interact with smart contracts through Etherscan, such as claiming tokens or executing functions, you must pay Ethereum gas fees. These fees go to miners or validators on the network, not to Etherscan.

Etherscan is simply the interface. The blockchain processes the transaction.

How Does Etherscan Make Money?

Etherscan generates revenue primarily through advertising, premium API plans, and enterprise analytics services. Banner ads and sponsored listings support free access for everyday users, while developers and businesses can pay for higher API limits and advanced data tools.

This model keeps blockchain information open and accessible without compromising decentralization.

Benefits of Using Etherscan

Etherscan empowers users with transparency, accuracy, and trust. It enables independent verification, improves security awareness, supports learning, aids investment research, and provides insight into decentralized finance, token markets, and blockchain infrastructure.

Conclusion

Etherscan is an essential tool for anyone interacting with Ethereum. It transforms complex blockchain data into clear, searchable, and verifiable information. Whether you’re tracking payments, analyzing smart contracts, learning how blockchain works, or validating transactions, Etherscan gives you full visibility into the Ethereum ledger.

With tools like Etherscan, blockchain moves from abstract technology to something you can actually see, verify, and trust. The best way to learn is to explore it yourself.

You've likely come across the term "ERC-20" in your crypto endeavours, with plenty of these token standards currently ranked in the top 10 (even top 100) cryptocurrencies. But what does ERC-20 actually mean, and what is a token standard? In this piece, we're uncovering everything you need to know about these popular crypto terms.

To start things off, ERC stands for Ethereum request for comment.

What is a token standard?

Let's start at the beginning. When Ethereum was created to provide developers with a platform on which to build decentralized apps (Dapps), the team incorporated several token standards. 

These token standards allow new projects to create, issue and deploy various functioning tokens on the blockchain. Each token standard is a smart contract that holds a set of particular "rules" that must be followed in order to be created.

In recent years a number of blockchain platforms that provide Dapp creation functionality have created their own token standards, however, for the sake of this article we are only looking at Ethereum.

The most popular token standards on Ethereum are the ERC-20, ERC-721, ERC-777, and ERC-1155 tokens. Each holds its own functionality and would be utilized depending on what the Dapp intends to use it for, i.e. will it be a transferable asset or be used to hold ownership rights. 

What is an ERC-20 token?

By far the most popular token standard utilized on the Ethereum network, the ERC-20 token is a fungible token that can be bought, sold and traded in the blockchain ecosystem. To date over 350,000 ERC-20 tokens have been created. 

Similar to the functioning of other cryptocurrencies like Bitcoin and Litecoin, ERC-20 tokens also hold value and are able to be bought and sold, however, they operate solely on the Ethereum blockchain. This means that all ERC-20 transactions conducted are executed on the Ethereum blockchain network.

The rules associated with this particular token ensure that it can function optimally on the Ethereum blockchain, and must be submitted to the community leadership for approval prior to its launch. While some rules are mandatory and others optional, the required ERC-20 rules are as follows:

• total supply: defines the total supply of the token
• balance of: indicates how many tokens are in a wallet address
• transfer To, Transfer From: must be able to be transferred from one user to another
• allowance: ensures that wallets have a sufficient amount before making a transaction
• approve: checks total supply against transactions

The optional elements are centred around the token's name, its ticker symbol and how many decimal places it would have %u200BFor instance, Ethereum's token name is Ether, its ticker symbol is ETH and it is divisible by up to 18 decimal places.

Examples of ERC-20 tokens are Augur (REP), Basic Attention Token (BAT), Maker (MKR), USD Coin (USDC) and OmiseGO (OMG).

Can you mine ERC-20 tokens?

ERC-20 tokens, unlike Ethereum and its native coins (ether), cannot be mined. That is, new tokens are 'minted' when a planned initial token offering (ICO) or security token offering (STO) event takes place. Usually, these events involve users sending ether to a smart contract address and in return receiving the newly minted ERC-20 token.

An ERC-20 token is technically a smart contract so it's possible for the developer team behind an ERC-20 token to issue new tokens at will. However, this isn't recommended because users would be less likely to trust these tokens if they could be minted at will. There must be a measure of scarcity in order for tokens to be valuable.

The pros & cons of ERC-20 tokens:

Some of the main benefits of ERC-20 tokens include: 

Fungible

Fungible ERC20 tokens are interchangeable, just like cash. Although the coins are technically distinct, they function in exactly the same way. You can trade one for another and they will be functionally equivalent, just like cash or gold.

Fungible tokens are fantastic, and there's a lot of value in the technical aspect. On a technical level, it's worth noting that fungible tokens don't add extra value to goods. They're typically beneficial in a variety of commercial scenarios.

Broad adoption

The popularity of ERC-20 tokens is quite apparent in the cryptocurrency industry. The number of exchanges, wallets, and smart contracts that already support newly-launched tokens has made it easy for new projects to integrate with them. There is plenty of developer support and documentation to go around.

Flexibility

The first thing to note about ERC-20 tokens is that they are highly flexible and may be used in a variety of circumstances and applications. This is due to the fact that these tokens are very customizable. They can be used in a lot of different scenarios such as Loyalty points programs, in-game currencies, or digital collectibles such as NFT's.

Some of the main cons of ERC-20 tokens include:

Mainstream

The popularity of ERC-20 tokens is also their greatest weakness. There are so many projects using the same standard that it's difficult to stand out from the crowd without differentiating your token in some way. Moreover, since they're essentially all the same on a technical level.

Fraud and Scams

It takes minimal effort to create a simple ERC-20 token, meaning that anyone could do it for good or bad purposes. As such you want to be careful with what you're investing in when considering blockchains projects because there are some Pyramid schemes masquerading as legitimate projects out there and trying to get unsuspecting investors involved in their scams. As a result, when looking at blockchain projects, you need to be cautious with what you invest in.

Other ERC Token Standards

While there is a large range of ERC tokens available, below we've outlined the most popular ones (excluding the ERC-20 one as it is listed above). 

ERC-721 

This token standard is for a non-fungible token (NFT) which gained huge popularity in the last year across the gaming and digital art worlds. These tokens represent ownership of something, and cannot be used interchangeably. 

ERC-777 

An evolution of the ERC-20 token, the ERC-777 provides more usability, particularly pertaining to its ability to mint or burn tokens. It also holds improved transaction privacy and an emergency recovery function. 

ERC-1155

This token standard allows for the creation of both utility tokens and non-fungible tokens. Making trading more efficient, the token standard allows for bundling of transactions which in turn saves costs.
