How this service works
Latest Transfer events of an ERC-20 token, optionally only those in or out of a wallet, over the last N blocks, with decimal-adjusted amounts. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.
Output
Returns a JSON object with the chain name, token contract address, token symbol, number of transfers found, blocks scanned, and an array of transfer events each containing sender address (de), recipient address (a), transaction hash, block number, and decimal-adjusted token amount.
Example use cases
Monitor whale wallet token flows
“Show me all USDC transfers in or out of wallet 0xb2cc224c1c9feE385f8ad6a55b4d94E92359DC59 on Ethereum over the last 100 blocks — I want to see the amounts adjusted for decimals and the transaction hashes.”
Audit recent token activity on Arbitrum
“Fetch the latest ARB token transfer events on Arbitrum for contract 0x912CE59144191C1204E64559FE8253a0e49E6548 over the last 200 blocks — no wallet filter, just give me all of them with sender, recipient, and amounts.”
Track stablecoin movement on Polygon
“Get me recent USDT transfers on Polygon for the USDT contract over the last 30 blocks and tell me how many transfers happened and the total blocks scanned.”

Endpoint
POSThttps://api.vextorium.com/erc20-transferencias-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain ERC-20 Transfer event data with decimal-adjusted amounts across multiple EVM chains, especially when you want to filter by wallet direction (inflows/outflows). It is ideal for real-time monitoring, wallet auditing, or DeFi analytics workflows without needing to run your own node or index events manually.
Side effects
- Invalid or non-ERC-20 token contract address returns an empty or error response
- Unsupported chain name causes a validation error
- Very large block ranges may return truncated results or time out
- Wallet address with no activity in the specified block window returns zero transfers
- Malformed wallet or token address causes a parsing error
