Solidity vs Verity. Right away, I notice `msgSender` and `msgValue` always have their values captured by local variables, there is an explicit `requireSomeUint` check, and the function that isn't part of this contract is declared with `external` and called with `externalCall`.

@tayyab but then address(0) is just the last 20 bytes of the Keccak-256 hash of an unknown public key. So I really doubt this argument is a valid reason for why there can't be a private key to address(0) @neynar @askgina.eth what's the correct argument for why EVM address(0) keys doesn't exist.

Has anyone converted your primary hot wallet into a smart wallet with EIP7702? Which implementation are you using? Safe Wallet still doesn't fully support 7702, right? https://github.com/safe-global/safe-smart-account/issues/997
