Blocks, Receipts, Logs

TL;DR

• Blocks/receipts/logs are exposed via Candid types.
• Receipt includes status, gas_used, effective_gas_price, contract_address, and logs.

Key Points

• logs[].logIndex is the in-block ordinal index
• receipt lookup can return Found/NotFound/PossiblyPruned/Pruned

Pitfalls

• Designing as if pruned history is always permanently queryable
• Mixing tx_id and eth_tx_hash lookup paths
