Have you ever been in a situation where a friend sends you a cryptocurrency like USDT over the Ethereum network and you’re unsure whether it has arrived in your wallet? The easiest way to confirm is by using a blockchain explorer to check the transaction record associated with your receiving address.
In this guide, we’ll walk you through the simple steps to verify ERC20 token transactions—using USDT as an example—so you can gain confidence in tracking your crypto assets.
What Is ERC20?
ERC20 is a technical standard used for creating and issuing tokens on the Ethereum blockchain. It defines a set of rules that all Ethereum-based tokens must follow, ensuring compatibility across various services like wallets and exchanges.
Many popular cryptocurrencies are issued as ERC20 tokens, including:
- USDT (Tether): A stablecoin pegged to the US dollar.
- UNI: The governance token of Uniswap.
- AAVE: Used within the Aave lending protocol.
- SUSHI: The utility token for the SushiSwap ecosystem.
- ENS: Associated with the Ethereum Name Service.
These tokens are widely used in decentralized applications (dApps), trading, and transfers across the Ethereum network and its scaling layers.
Step 1: Identify the Correct Network
Before checking your transaction, determine which blockchain network the tokens were sent through. Ethereum consists of:
- Ethereum Mainnet: The base layer where most original ERC20 tokens reside.
Layer 2 Networks: Scalability solutions that process transactions off the main chain. Popular examples include:
- Arbitrum
- Optimism
- zkSync
- StarkNet
Ask the sender which network they used. This is crucial because each network has its own block explorer.
💡 Note: Sending tokens on the Ethereum Mainnet can involve high gas fees. Many users prefer Layer 2 solutions for faster and cheaper transactions.
Step 2: Access the Right Block Explorer
A block explorer is a tool that allows you to view transactions, addresses, and token balances on a blockchain. Each network has its own dedicated explorer.
Here are the most commonly used explorers for ERC20-compatible networks:
- Ethereum Mainnet: Etherscan
- Arbitrum: Arbiscan
- Optimism: Optimistic Etherscan
- zkSync: zkSync Explorer
- StarkNet: Starkscan
Open the explorer that matches the network used for your transaction.
Step 3: Check Transaction History Using Your Address
Let’s assume you received 500 USDT via the Ethereum Mainnet. Here’s how to check:
- Go to Etherscan.
- Paste your Ethereum wallet address (starting with “0x”) into the search bar.
- Press Enter to view your address overview.
On your address page, you’ll see:
- Current token balances
- Recent transaction history
To filter only ERC20 token transfers (like USDT):
- Click on the “Token Transfers” tab.
You’ll now see a list of all ERC20 token transactions. Look for the latest entry involving USDT—it should show the amount received and the timestamp.
Example:
From: 0x9d3a... | To: [Your Address] | Value: 500 USDT | Age: 2 mins ago
If the transaction is confirmed, your tokens have arrived successfully.

Frequently Asked Questions
What does “ERC20” stand for?
ERC20 stands for “Ethereum Request for Comment 20.” It is a widely adopted standard that allows developers to create fungible tokens on the Ethereum blockchain. These tokens are interoperable with wallets, exchanges, and smart contracts.
Can I use the same method for other tokens?
Yes. This method works for any token built on the ERC20 standard, including stablecoins, utility tokens, and governance tokens. Simply use the relevant block explorer for the network in question.
What if my transaction doesn’t show up?
First, confirm that the sender used the correct address and network. Transactions can sometimes be delayed due to network congestion. If it’s been a long time, you may also check the sending address or transaction hash (if provided).
Are block explorers safe to use?
Block explorers are read-only tools. They don’t require you to connect your wallet or enter private keys, so using them is generally safe. However, always ensure you’re on the official website to avoid phishing scams.
Do I need to pay to use a block explorer?
No, block explorers are free to use. They provide transparent access to blockchain data for everyone.
Can I check transactions on mobile?
Yes, most block explorers have mobile-friendly websites. Some also offer dedicated apps for iOS and Android.
Tracking ERC20 token transactions is a simple yet essential skill for anyone using Ethereum-based assets. By using the correct block explorer and your wallet address, you can easily monitor incoming and outgoing transfers—whether you’re receiving USDT, ETH, or any other token.
Remember, always double-check the network and address before sending or receiving crypto. Happy tracking!
