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?

Sha256 and similar hash functions are considered quantum safe. STARKs use hash functions heavily and so are also considered quantum safe. So in a pinch you could hard fork an upgrade where everyone switches to a new key, and a zk proof of knowledge is used for the new private key instead of normal signatures.

i'm thinking no time for hard fork, like literally being blindsided and seeing coins start moving out of big accounts granted, everything likely goes to zero in this scenario but my point is what could one individual do to protect themselves from falling victim before social coordination can step in

I don't think there's anything ready off the shelf, but maybe build something that requires a kyber signature, and verified with a snark in /risc-zero so you don't need to verify the pq signature itself in the EVM. https://github.com/Argyle-Software/kyber

Actually Falcon probably makes more sense 😅 https://blog.cloudflare.com/another-look-at-pq-signatures/ https://github.com/aszepieniec/falcon-rust
