eth_getTransactionReceipt

Returns the receipt of a transaction by transaction hash on Flow EVM Gateway. Receipt is only available for mined transactions.

Why Flow EVM? Build on the EVM-equivalent layer on Flow blockchain enabling Cadence+Solidity composability with full EVM equivalence on Flow, atomic multi-operation transactions, 40% lower gas fees, and 473% contract growth in 2025.

Use Cases#

The eth_getTransactionReceipt method is essential for:

Transaction confirmation - Verify transaction was mined successfully
Gas analysis - Check actual gas used vs estimated
Event parsing - Read emitted events from logs
Status verification - Confirm success/failure for consumer NFTs (NBA Top Shot, Disney Pinnacle), gaming dApps, and hybrid Cadence-EVM applications
