eth_getTransactionReceipt

eth_getTransactionReceipt returns the execution receipt for a transaction that has already been mined on the Avalanche C-Chain (chain ID 43114), the EVM chain whose gas is paid in AVAX. The receipt is the authoritative record of what happened when the transaction ran: its success-or-revert status, the gas it consumed, and every log event it emitted. Send the request to https://avalanche.therpc.io/YOUR_API_KEY. Because the C-Chain reaches finality under Snowman consensus in roughly one to two seconds, a receipt usually becomes available very soon after submission — but only once the transaction is actually included in a block.

Use cases

• Confirm whether a C-Chain transaction succeeded or reverted after it was mined by reading the status field (0x1 vs 0x0).
• Extract the emitted logs — for example Trader Joe swaps or Aave deposit events — to update application state from on-chain activity.
• Retrieve the address of a freshly deployed contract via the contractAddress field, which is non-null only for deployment transactions.
• Calculate the exact AVAX fee paid by multiplying gasUsed by effectiveGasPrice.

Errors & troubleshooting

Common pitfalls

• A pending transaction has no receipt yet, so the call returns null. Poll until you get a non-null result rather than assuming it is ready; on the C-Chain finality is fast (about 1–2 seconds), so the wait is usually short.
• A status of 0x0 means the transaction was included in a block but reverted — the AVAX gas was still spent, even though the state change did not take effect.
• For ingesting every receipt in a block, eth_getBlockReceipts is far more efficient than calling this method once per transaction hash.
