@zerosnacks I'd like to work on this. can I go ahead

[zerosnacks]

Hi @codeWhizperer

Sure! Assigned to you

[codeWhizperer]

@zerosnacks. when I execute cargo run --example trace_call_many, I get the error: method trace_callMany not supported.

My question is, which rpc supports these methods?

[zerosnacks]

Hi @codeWhizperer, that is expected behavior from public RPCs as simulation is quite a heavy RPC method usually reserved for non-free tiers.

I've made some small tweaks to your PR to use local Reth bindings which works 💯
