How this service works

Token and native transfer history for any EVM address across major chains: direction, counterparty, asset, exact decimal value, block and transaction hash, filterable by category and block range with a cursor for paging. Use it to reconstruct what an address actually did, rather than only what it holds now.

Output

Returns a paginated JSON object containing the transfer count, network details, a page cursor for continuation, and an array of transfer records — each with sender, recipient, transaction hash, block number, timestamp, asset name, token value, raw value, decimals, contract address, token ID, and category (e.g. erc20, erc721).

Example use cases

Audit incoming USDC payments to a wallet

“Fetch the last 25 inbound USDC transfers to 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum, filtering by the USDC contract 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48, ordered newest first.”

Track NFT transfers from a collector

“Get all ERC-721 transfers sent out from wallet 0xAbCd1234... on Polygon, starting from block 0, up to 50 results per page — I want to see what NFTs this address has been sending.”

Monitor DeFi activity on Base for a contract

“Pull the most recent 100 ERC-20 and ERC-1155 token transfers involving address 0x1234abcd... on Base, including both inbound and outbound, and show me the oldest ones first so I can trace activity from the beginning.”

When to prefer

Choose this endpoint when you need comprehensive, paginated on-chain transfer history for a specific EVM wallet or contract across major networks (Ethereum, Base, Polygon, Arbitrum, Optimism). It is ideal for auditing wallet activity, tracking token flows, building portfolio history, or monitoring NFT movements — especially when you need filtering by asset category, direction (in/out), counterparty, or specific token contracts. Prefer this over block explorers when you need structured JSON output ready for agent consumption without API keys.

Side effects

Invalid or malformed EVM address returns a 400 error
Unsupported network name returns an error — only ethereum/base/polygon/arbitrum/optimism are valid
Inner dimensions mismatch if both address and contracts are omitted
pageKey from a different query or expired cursor returns no results or an error
maxCount outside 1–100 range is rejected
Block numbers specified as invalid hex or decimal strings may cause a parse error
