How this service works
Receipt of a mined EVM transaction: success or revert, gas used, effective gas price, fee (and L2 L1 fee), created contract and event logs with Transfer and Approval decoded. Use to confirm a payment or swap.
Output
Returns a structured receipt object containing: transaction success or revert status, gas used, effective gas price, total fee paid (plus L1 fee for L2 chains like Base/Optimism/Arbitrum), the address of any newly created contract, and a list of event logs with Transfer and Approval events decoded into human-readable form.
Example use cases
Confirm DeFi swap completion
“Can you check whether my Uniswap swap on Arbitrum succeeded? The transaction hash is 0x7f3e...d91a — tell me the status, gas cost, and any Transfer events that were emitted.”
Verify cross-chain payment receipt
“I sent USDC on Optimism and want to confirm it landed — please pull the receipt for 0x4c2b...88fe and tell me if it succeeded, what the L1 and L2 fees were, and show any Transfer logs.”
Debug failed contract deployment
“My smart contract deployment on Ethereum might have reverted — can you look up the receipt for transaction 0x91da...03cc and tell me if it succeeded or reverted, and whether a contract address was created?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/evm/receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to confirm the outcome of a specific EVM transaction — whether it succeeded or reverted, how much gas was consumed, what fees were paid (including L1 fees on L2 chains), and what on-chain events were emitted. It is ideal for confirming payments, token transfers, swaps, or contract deployments by hash. Prefer this over block explorers when you need structured, machine-readable output with decoded Transfer and Approval events ready for downstream processing.
Side effects
- Transaction hash not yet mined — receipt not available (transaction still pending)
- Invalid or malformed transaction hash format
- Unsupported chain name provided
- Transaction hash does not exist on the specified chain
- Network or RPC timeout causing unavailable receipt data
