Great work! I've left a few comments what could be reworked in my opinion

I see that EvmContext confuses. The reason why we used EvmContext with an EvmContext::Address associated type is that there are some EVM forks that have different address formats.
For example, Ronin supports ronin:ec49280228b0d05aa8e8b756503254e1ee7835ab, but other EVM chains do not.
As far as I know, Aptos has only one address format (at least for now), so AptosContext and AptosAddress are not needed.
Therefore, the signer can be just:

pub struct Signer;

impl Signer {
  pub fn sign_proto_impl(...) {
    // ...
    let sender = Address::from_str(&input.sender)?;
    // ...
 }
}
