How this service works
EVM transaction + receipt + decoded ERC20 transfers in ONE call — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object containing transaction status (success/fail), sender and recipient addresses, block number, number of confirmations, gas used, native fee, and an array of decoded ERC20 transfer events (each with from/to addresses, token contract address, and raw token amount), plus a receipt object with receipt ID and USD amount.
Example use cases
Verify a USDC payment on Base
“Can you confirm that transaction 0x4f2a...8b91 on Base went through successfully and show me what USDC amounts were transferred and to which addresses?”
Debug a failed DeFi swap
“I need to check Arbitrum transaction 0xd8e1...3c72 — did it succeed or fail, and what ERC20 tokens changed hands during it? Also show me the gas used.”
Audit token movements for compliance
“Pull the full receipt and all ERC20 transfers for Polygon transaction 0x99f0...1a44 so I can see exactly which token addresses sent and received funds in that transaction.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/evm-tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need transaction data, receipt, and ERC20 transfer decoding all in one round-trip instead of making separate calls to a node RPC. It is ideal for agents verifying payments, auditing DeFi activity, or checking token movements on Ethereum, Base, Polygon, Arbitrum, or Optimism without managing raw RPC infrastructure.
Side effects
- Invalid transaction hash format (must be 0x-prefixed 64 hex chars) returns validation error
- Transaction hash not found on the specified chain returns found: false
- Unsupported chain value returns schema validation error
- Network timeout or RPC unavailability may cause delayed or failed responses
- Transaction exists but has no ERC20 transfers returns empty erc20_transfers array
