More Details Connect to Claude

Connect your Etherscan API key to any AI agent and gain instant access to on-chain data across Ethereum and other EVM-compatible networks through natural conversation.

What you can do

  • Native Balances — Retrieve the native token balance (ETH, MATIC, etc.) for single or multiple addresses (up to 20) using get_balance and get_balance_multi.
  • Transaction History — Fetch comprehensive lists of normal and internal transactions for any wallet address with get_tx_list and get_tx_list_internal.
  • Token Tracking — Monitor transfers for ERC-20, ERC-721 (NFTs), and ERC-1155 tokens using specialized tools like get_token_tx and get_token_nft_tx.
  • Multi-Chain Support — Query data across different networks by specifying the chainid (e.g., 1 for Ethereum, 137 for Polygon).
  • Granular Filtering — Filter transaction results by block range, pagination, and sort order to find exactly what you need.

What is the ETH balance of address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe on Ethereum?

I've checked the balance for that address on Chain ID 1. The current balance is approximately 425.12 ETH (425123456789012345678 wei).

Show me the last 5 ERC-20 token transfers for 0x742d35Cc6634C0532925a3b844Bc454e4438f44e.

I've retrieved the ERC-20 transfer history. The most recent transfers include 500 USDT from 0xabc... and 100 LINK to 0xdef... Would you like more details on any of these transactions?

List the normal transactions for address 0x123... on Polygon (Chain ID 137).

Querying Polygon scan... I found 10 recent transactions for that address. The latest was a contract interaction with Uniswap V3. Would you like me to list the specific transaction hashes?

You can use the `get_balance_multi` tool. Provide the `chainid` (e.g., 1 for Ethereum) and a comma-separated list of up to 20 addresses to retrieve all balances in a single request.
