The problem Post Quantum Secure Transaction solves

Currently, becuase of ECDSA, signature of any transaction can cause private key to leak post quantumly. Using ZK STARKs and Account Abstraction, I have shown how one can do quantum secure signature without modifying underlying Ethereum layer. This can be done by using Cairo to generate a ZK STARK proof which creates the proof that "I know the preimage of the address", which is the public key and only the owner can know it, this proof is broadcasted to modified Starkex contracts via Account Abstraction. It takes 10 transactions to verify one proof, 9 of them are to the sender itself.

Challenges we ran into

Trampoline and Bundler are at a very fragile state. Testing was difficult due to expense transaction gas fee.
