eth_getBlockReceipts on Arbitrum One
Returns every transaction receipt in a block in one call — far cheaper than looping eth_getTransactionReceipt per tx. Ideal for indexers ingesting blocks.
One call replaces N per-tx receipt calls, so it's the fastest way to ingest logs + statuses while indexing. Some older clients don't implement it — fall back to per-tx receipts on a method-not-found error.
