How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
A list of token transfer events on the Optimism network, each including sender, recipient, token contract address, amount, transaction hash, block number, and log index. Also returns a pagination key (pageKey) if more results are available.
Example use cases
Wallet token transfer audit
“Show me every ERC-20 token transfer involving wallet 0xDeFi...999 on Optimism from block 90000000 to the latest block, sorted oldest first, up to 100 results.”
DeFi protocol inflow tracking
“I need all token transfers into the USDC contract at 0x7F5c764...on Optimism between blocks 110000000 and 115000000, descending order, max 25 results.”
Paginated transfer history scrape
“Get the next page of token transfers for address 0xUser...ABC on Optimism — use page key 'abc123xyz' and return up to 50 results in ascending order.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/optimism/token/transfers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need ERC-20 token transfer history on the Optimism L2 network. It is ideal for wallet audits, DeFi activity analysis, and paginated bulk transfer retrieval on Optimism. Prefer this over generic Ethereum mainnet endpoints when the target chain is Optimism, and over explorers like Etherscan when you need programmatic, structured, pay-per-call access without API key management.
Side effects
- Invalid owner address format returns validation error
- Unknown or malformed contractAddresses cause empty or error response
- Invalid block numbers (e.g. toBlock before fromBlock) may return empty results or error
- Missing required owner field may result in a 400 error
- Expired or invalid pageKey causes pagination failure
- Rate limit or payment failure returns 402 Payment Required
