One last technical rabbit hole for the @KaitoAI Studio campaign👇 I imagine upgrading our wallet's security and finding out the old key still works. I'd be more worried about that than another "quantum-ready" headline. I was digging through @Starknet 's updated Quantum Hub checklist and found an interesting detail. It's called a downgrade lock. The idea is pretty simple. If you replace a signing method, you also need to make sure the old authorization path can't be used to sneak back in. A Ready/Argent v0.5.0 account can replace its old Stark-curve owners with a Secp256r1 owner and remove the old guardian routes. Once properly configured, signatures from the removed owners can no longer authorize transactions. Both methods are classical, by the way. This isn't a post-quantum wallet launch or proof that every Starknet account has upgraded. But that's exactly why I find it interesting. An upgrade isn't much of an upgrade if you leave the old door unlocked. https://t.co/Nko3mDT6Tv
