How this service works
Token Transfer History (optimism). Optimism token transfer history: ERC-20 and ERC-721 Transfer events for a token, filtered to one wallet (?wallet=, in/out labelled, up to 2,000 blocks) or the latest 20 blocks unfiltered. Decoded amounts, up to 200 rows.
Output
A list of token transfer events associated with the given Optimism wallet address, each including transaction hash, block number, timestamp, sender address, recipient address, token contract address, and token amount transferred.
Example use cases
Audit wallet token flows
“I need to audit all token transfers for the Optimism address 0xAbCd...1234 — can you fetch the complete on-chain transfer history so I can review every token sent and received?”
Track DeFi portfolio activity
“Show me the token transfer history for my Optimism wallet 0x9F2e...8a01 so I can see what DeFi activity has happened — inflows, outflows, all of it.”
Investigate suspicious wallet movements
“Can you look up all token transfers on Optimism for the address 0x7c3A...b55F? I want to see if there are any unusual or large token movements in the transaction history.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/optimism/transfers/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need token transfer history on the Optimism Layer 2 network. It is distinct from Base, BSC, or Ethereum mainnet transfer history endpoints offered by the same provider. Prefer this over generic blockchain explorers when you need a programmatic, agent-callable API with per-call micropayment pricing via x402 and no API key setup.
Side effects
- Invalid or malformed wallet address returns an error response
- Address with no transfer history may return an empty list
- Network connectivity issues or Optimism RPC node failures could cause timeouts
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Newly created addresses with no history return empty results
