debug_traceCallMany - Robinhood

debug_traceCallMany. Executes and traces multiple call objects against a given block state.

debug_traceCallMany - robinhood [Value: 20CU]
Runs and traces multiple call bundles in sequence against the state of a given block, without broadcasting anything
Use cases

Use cases

  • Debug a bundle of transactions intended for private submission
  • Preview how several draft transactions would interact against current state
Constraints

Constraints

  • Bundles are executed in order, each seeing the state left by the previous one
  • Large bundles or many bundles at once can be slow to trace
