eth_getBlockReceipts

eth_getBlockReceipts returns every transaction receipt for an Avalanche C-Chain block in a single call — each with its logs, gas used, effective gas price (in AVAX wei), and success/failure status. For indexers it collapses what would otherwise be one request per transaction into one round trip, which matters on a chain that finalizes blocks every one to two seconds. Pass a block tag to https://avalanche.therpc.io/YOUR_API_KEY (chain ID 43114) and get the whole block's receipts back as an array.

Use cases

• Ingest every event in a C-Chain block for indexing with a single RPC call instead of per-transaction lookups.
• Calculate total gas used and the AVAX fees paid across all transactions in a block.
• Scan all ERC-20 Transfer logs in a block to update token balances for assets like USDC or WAVAX.
• Identify failed transactions (status "0x0") in a block for error analysis and alerting.

Errors & troubleshooting

Common pitfalls

• Far more efficient than N calls to eth_getTransactionReceipt — always prefer this for block-level receipt ingestion on the C-Chain.
• A block with many transactions and verbose logs can produce a large response; stream or chunk your processing if memory or bandwidth is constrained.
• Not every node or provider exposes this method; confirm availability on your Avalanche endpoint before depending on it in production.
