debug_intermediateRoots - Robinhood

debug_intermediateRoots. Returns the intermediate state roots produced while executing a block's transactions.

debug_intermediateRoots - robinhood [Value: 20CU]
Re-executes every transaction in a block and returns the state root produced after each one
Use cases

Use cases

  • Pinpoint which transaction caused an unexpected state change
  • Debug a state-root mismatch between clients on a specific block
  • Build fine-grained, per-transaction state-diff tooling
Constraints

Constraints

  • Re-executes every transaction in the block, which is resource-intensive
  • Requires an archive node for blocks other than recent ones
