Thanks for the feedback, thats exactly the purpose of the forum post. Can you elaborate why enforcement at the protocol level is bad? We think that the added complexity at the protocol ‘might’ be worth it or at least worth a discussion. The question is should every account be able to verify an off chain message? We think yes as that would allow a number of features that account abstraction enables(sign-in, messaging etc). SIWS(Sign-in-with-Starknet) with better recovery features because of AA could be a very important/unique feature of Starknet. Ofcourse it goes without saying it should be part of the Account Standard SNIP
