imagine ECDSA is demonstrated to be broken by quantum computing tomorrow

now everyone’s scrambling to move funds into a smart wallet with quantum-resistant signature verification ASAP

what’s the best implementation of this currently out there? does one even exist?

You can change the signature scheme with modules.

in this scenario you could still get popped with a safe; the attacker just busts enough ECDSA keypairs to crack it

the thought experiment here is effectively “imagine given a ECDSA public key an attacker can derive the private key”
