@onbjerg onbjerg commented Jun 20, 2024

Motivation

EIP-7702 is up for inclusion in Prague.

Solution

Adds helpers and some types specified in EIP-7702.

The transaction type itself will be added in another PR as it is not relevant right now (for example, the RPC spec has not been updated yet).

This also adds a k256 feature to alloy_eips since authority recovery requires signature recovery which is only possible with k256 enabled in alloy_primitives

  • Added Tests

Can we add RecoveredAuthorization? Where we will cache the recovered account as Option<Address (Option as it can fail).

Recovery can be expensive and can be done before revm gets called. We are okay to do that as it is covered by gas.

The idea that I have is to have an enum in Revm as input:

AuthorisationList {
   Recovered(Vec<RecoveredAuthorization>),
   Signed(Vec<SignedAuthorization>),
}

Would be good to have seck256k1 lib/feature flag as it is faster. But looking at it as a low priority.
