How this service works
Status of an EVM transaction by hash: pending, success or failed, block, confirmations, timestamp, from/to, value, gas used, fee (plus L1 fee on Base/Optimism) and ERC-20 token transfers. Searches Ethereum, Base, Arbitrum, Optimism and Polygon if no chain is given. Use to confirm a payment settled.
Output
Returns a JSON object with transaction status (pending, success, or failed), block number, number of confirmations, timestamp, from and to addresses, ETH/native value, gas used, total transaction fee, L1 fee (on Base/Optimism), and a list of ERC-20 token transfer events. If no chain is specified, the service searches across Ethereum, Base, Arbitrum, Optimism, and Polygon automatically.
Example use cases
Confirm crypto payment settled
“I just sent USDC to a client on Base — can you check if transaction 0xabc123...def456 has confirmed and tell me the block it landed in and the total fee paid?”
Verify cross-chain token transfer
“Can you look up this Arbitrum transaction hash 0x7f9fade1c0d57a7af66ab4ead79fade1c0d57a7af66ab4ead7c2c2eb7b11a91385 and tell me what ERC-20 tokens were transferred, from which address, and whether it succeeded or failed?”
Debug a stuck pending transaction
“My Polygon transaction 0x3d2341aef12093a8d6e8d9f1234567890abcdef1234567890abcdef1234567890 has been sitting for a while — is it still pending, and can you tell me the gas price used and how many confirmations it has so far?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/crypto/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to confirm whether a specific EVM transaction has settled, determine its confirmation count, inspect fees (including L1 fees on rollups like Base and Optimism), or see ERC-20 token transfers associated with a hash. It covers five major EVM chains and auto-searches if no chain is provided, making it the best single-call option for multi-chain transaction verification without needing separate per-chain queries.
Side effects
- Transaction hash not found on any supported chain — returns not found or empty result
- Invalid hash format (not 0x + 64 hex chars) — returns validation error
- Transaction still pending — status returned as 'pending' with zero confirmations
- Chain specified is not supported — returns error for unsupported chain value
- Network or RPC provider outage may cause timeout or incomplete data
