How this service works
Live transaction receipt by hash via `eth_getTransactionReceipt`: success/failed status, block number, from/to, created contract address, gas used, cumulative gas, effective gas price (wei + gwei), tx type and the emitted event logs (capped). Complements `tx` (which reads the transaction itself). Returns `found:false` for unknown/pending hashes. Reads live on-chain data with automatic endpoint fallback.
Output
Returns a JSON object with found:true/false. When found, includes: success/failed status, block number, from and to addresses, contract address if a deployment, gas used, cumulative gas used, effective gas price in wei and gwei, transaction type, and an array of emitted event logs (capped). Returns found:false for unknown or still-pending transaction hashes.
Example use cases
Confirm DeFi swap landed on-chain
“I just submitted a token swap on Base — the tx hash is 0xabc123...def456. Can you pull the receipt and tell me if it succeeded and what block it confirmed in?”
Verify smart contract deployment address
“I deployed a contract on Ethereum and the hash is 0x9f8e7d6c5b4a3f2e1d0c9b8a7f6e5d4c3b2a1f0e. Can you fetch the receipt and tell me the address the contract was deployed to?”
Audit gas costs for a transaction
“For Arbitrum transaction 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b, what was the effective gas price paid and total gas used?”
Technical details
Endpoint
POSThttps://chain.openverbs.com/v1/receiptWhen to prefer
Use this endpoint when you need post-execution confirmation data — whether a transaction succeeded, exactly how much gas was consumed, what events were emitted, or the address of a newly deployed contract. Prefer this over the sibling `tx` endpoint (which reads the raw transaction itself) when you need execution results rather than the original call parameters. Supports Ethereum, Base, Arbitrum, Optimism, and Polygon with automatic RPC fallback for reliability.
Side effects
- Unknown or pending hash returns found:false rather than an error
- Invalid hash format (not 0x + 64 hex chars) rejected by schema validation
- Unsupported chain name returns a validation error
- Network or RPC endpoint unavailability may cause delayed or failed reads despite automatic fallback
- Event log array may be capped if the transaction emitted a large number of logs
