Read Any ERC-20: Using the Peek Tool & Explorers

The Peek a Token panel in the Lab lets you read basic metadata (name, symbol, decimals) for any ERC-20 on your selected testnet.

Open Token Lab →

Steps

1. Open /token-lab/ and pick a testnet (e.g., Ethereum Sepolia).
2. Paste a token contract address (starts with 0x and is 42 chars long).
3. Click Read. You’ll get an alert with name/symbol/decimals.

Find token addresses

• Use the linked explorer (e.g., Sepolia Etherscan).
• Copy the Contract address from the token page.

What if it fails?

• Make sure you’re on the same testnet where the token was deployed.
• Double-check the address format (0x + 40 hex chars).
