Description

#[cfg_attr(feature = "serde", derive(serde::Serialize, serde::Deserialize))]
pub struct AccountInfo {

matches the non standard eth_getAccountInfo endpoint response:

https://github.com/alloy-rs/alloy/blob/c04ef82f3a63c97cb3332a78b3c18dca47966ad3/crates/rpc-types-eth/src/account.rs#L9-L21

this means for an rpc db this could be replaced with single rpc call if the node supports that endpoint and directly deserialize into revm AccountInfo if deserialize is manually impl so that the codehash is computed during deserde

   let (nonce, balance, code) = tokio::join!(nonce, balance, code,);

TODO

  • add manual deserde that in addition to the current format also supports the eth_getAccountInfo response

Research direction
Examine the existing `AccountInfo` struct in revm (likely in `crates/rpc types eth/src/account.rs` or similar) and its current `serde::Deserialize` derive. Understand the non standard `eth getAccountInfo` endpoint response format as referenced in the Alloy repository. Implement a custom `Deserialize` that supports both the current format and the new format, computing the codehash during deserialization. Review the linked code snippet with `tokio::join` for context on concurrent fetching.
