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?

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”

You can change the signature scheme with modules.
