eth_getBlockReceipts

eth_getBlockReceipts returns every transaction receipt in a single OP Mainnet block in one call — status, gas used, effective gas price, and the full log set for each transaction. On this OP Stack rollup, where gas is paid in ETH and blocks arrive about every 2 seconds, it is the most efficient way to ingest a block's events without firing off one request per transaction. Send the block tag to https://optimism.therpc.io/YOUR_API_KEY (chain ID 10, 0xa).

Use cases

• Ingest every event in an OP Mainnet block for an indexer in a single RPC call instead of N receipt fetches.
• Sum gasUsed and effectiveGasPrice across a block's transactions to compute total L2 fees paid in ETH.
• Scan all ERC-20 Transfer logs in a block — e.g. Velodrome or Synthetix token movements — to keep balances in sync.
• Identify failed transactions (receipt status of "0x0") in a block for error analysis and alerting.

Errors & troubleshooting

Common pitfalls

• Far cheaper than N separate eth_getTransactionReceipt calls — always prefer this for block-level receipt ingestion on OP Mainnet.
• A busy OP Mainnet block with many log-heavy transactions can return a large payload; stream or chunk the response if memory or bandwidth is tight.
• Some nodes and providers do not implement this method — confirm it is available on your endpoint before depending on it in production.
