Add "onlyTopLevelCall" to debug_traceTransaction request data

[antazoey]

Component

Anvil

Describe the feature you would like

To get return values from Alchemy, I use this tracer config in debug_traceTransaction:

{"tracer": "callTracer", "tracerConfig": {"onlyTopLevelCall": true}}

This is much faster and uses way less memory than parsing the full trace.

I would like to be able to do the same when chatting up a Foundry node (via RPC).

Unless there is a different way I can the return value for a transaction via its hash?

Hi @antazoey thanks for flagging this

Added to A-reth-anvil Area: reth-anvil , this is something Reth already supports out-of-the-box using onlyTopCall in the callTracer configuration and will be implemented part of the reth-anvil project
