eth_getTransactionReceipt

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

Why Unichain? Build on Uniswap's DeFi-optimized Superchain L2 with 250ms sub-blocks and 95% lower costs than Ethereum with 250ms sub-blocks (fastest L2), TEE-secured block building, native Superchain interoperability, and 65% revenue to validators.

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 decentralized exchanges, liquidity protocols, and MEV-protected DeFi applications
