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?

Back to the top of the thread, but it occurs to me that you could also do a snapshot/fork and require any transaction to include a zk proof that the sender knows their bip39 seed phrase, since that should be quantum safe. Of course not everyone knows a bip39 phrase and derivation path for every key they hold, but it would be a good start.
