eth_getTransactionReceipt

eth_getTransactionReceipt returns the execution receipt for a transaction that has already been mined on Arbitrum One — the Optimistic Rollup that settles to Ethereum L1 and pays gas in ETH. Given a transaction hash, it reports the outcome once the sequencer has included the transaction in a block: the success/revert status, the gas consumed, and every log the transaction emitted. On Arbitrum One the receipt also reflects the chain's two-part fee model, where the cost combines L2 execution and L1 calldata posting, both denominated in ETH.

Use cases

• Confirm whether a swap on GMX or Camelot, or a deposit into Aave, succeeded or reverted once the sequencer mined it by reading the status field.
• Extract the emitted logs — such as ERC-20 Transfer or Uniswap Swap events — to update balances and application state.
• Read contractAddress to capture the address of a freshly deployed contract; it is non-null only for deployment transactions.
• Compute the exact ETH fee paid as gasUsed * effectiveGasPrice, which on Arbitrum One folds in both the L2 execution and L1 calldata components.

Errors & troubleshooting

Common pitfalls

• A pending transaction returns null. Arbitrum's sequencer gives sub-second soft confirmations, but you should still poll until the result is non-null rather than assume the receipt exists immediately after broadcast.
• A status of "0x0" means the transaction was mined but reverted on-chain — the ETH gas was still consumed even though the call failed.
• To ingest every receipt in a block, call eth_getBlockReceipts once instead of issuing one eth_getTransactionReceipt per transaction; it is far more efficient and uses fewer compute units.
