This is a contribution to Post Quantum Ethereum world! Made in Scaling Etheruem 2024 Hackathon.
Quantum computers will be here one day. Without proper preparation, there will be significant damage. Quasar, a post-quantum account abstraction (PQAA), is part of a wider effort to prepare for post-quantum Ethereum.
Shor's algorithm on quantum computers can efficiently solve the elliptic-curve discrete logarithm problem and break ECDSA, BLS, etc., which are the signature schemes we use in Ethereum. There are some preparations that we can make to mitigate the damage when Q-day comes. This work is one of them.
Quasar is a smart contract wallet (AA) and browser extension.
Quasar is still a functional proof of concept (PoC). We do not recommend using it in production environments.
The built extension files can be found in /extension/extension, user can directly import this to chrome/chromium to use the extension.
