How this service works
Human-readable summary of a Arbitrum One transaction: status, block and time, sender and recipient, ETH value, gas used and fee, method selector, and decoded ERC-20 transfers with token symbols and amounts.
Output
A JSON object containing the transaction hash, chain identifier, status (success/failure), block number, ISO timestamp, sender and recipient addresses, native ETH value, gas used, fee in ETH, method selector, native token symbol, decoded ERC-20 token transfers (each with from/to addresses, token contract, symbol, raw and human-readable amount), and contract created address if applicable.
Example use cases
Confirm a USDC payment on Arbitrum
“I just sent USDC to a vendor on Arbitrum — can you check transaction 0x582f03573ec27992f7746f4a167ba98b1b337330ac7ec72b5d641a4991b0b598 and confirm it went through, how much was sent, and to which address?”
Debug a failed DeFi transaction
“My Arbitrum swap transaction 0xabc123def456...7890 seems to have failed — can you pull up the full details including status, gas used, and what method was called so I can figure out what went wrong?”
Audit an ERC-20 transfer for bookkeeping
“I need the details of Arbitrum tx 0x582f03573ec27992f7746f4a167ba98b1b337330ac7ec72b5d641a4991b0b598 for my records — specifically the token symbol, amount transferred, sender, recipient, block number, and timestamp.”
Technical details
Endpoint
GEThttps://onchaincheck.dev/arbitrum/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a complete, human-readable breakdown of a specific Arbitrum One transaction — particularly when you need decoded ERC-20 transfer details (token symbols and amounts) alongside gas and status information. Prefer this over raw RPC calls when you want decoded token transfer data without writing your own ABI decoding logic. Choose this over Ethereum or other chain endpoints specifically for Arbitrum One transactions.
Side effects
- Invalid or malformed transaction hash (not matching 0x + 64 hex chars) returns a validation error
- Transaction hash not found on Arbitrum One returns a not-found error
- Network connectivity issues with Arbitrum RPC nodes may cause transient failures
- Very recent transactions not yet indexed may not be retrievable immediately
