Chunk by Block and Shard
chunk request type
Use this when you know the block and shard coordinates and want to inspect exactly what that shard executed in that block.
This is the most natural RPC route for cross-shard debugging because it answers the practical question “what did shard X execute in block Y?” The response gives the chunk header plus the transactions and receipts in that shard-local execution unit. If you already have the exact chunk hash, use Chunk by Hash. If you want the fuller per-shard envelope with state changes and produced receipts, use Block Shard. For a worked tracing example, see RPC Examples.
Fetch a single chunk's transactions and receipts by its parent block plus shard index.
