This repository illustrates how theStateProviderFactory fromreth can be implemented withalloy-rs to fetch all state using RPC. This can be useful to not be dependent on a real database when testing reth ExEx.

There is nodebug_codeByHash implemented currently (seefeat(rpc): debug_codeByHash #14479). But since revm will first callbasic_account, we can cache it and return it whenbytecode_by_hash is called.

Currently, this repos purpose as copy/paste reference and not as library. Not all functions are implemented.

See tests insrc/alloy_reth_provider.rs for an example.

// Init the providerlet provider =ProviderBuilder::new().on_http("https://eth.merkle.io".parse().unwrap());// Init the db providerlet db_provider =AlloyRethProvider::new(provider);// Use the StateProviderFactorylet state = db_provider.state_by_block_id(BlockId::number(16148323)).unwrap();

Many, many thanks to the team ofreth andalloy-rs for the awesome work they do. Some parts of the trait implementation are taken from reth. Also, many thanks torevm. Thealloy_db part is a copy/paste from revm because this part is not included in the latest revm version, and it makes it easier to be in sync with the latest Alloy version.
