Most wallet security still depends on a single seed phrase, while post-quantum proposals often focus on replacing signature algorithms without rethinking how people actually secure their assets.
This talk introduces Bunker Wallet, a working implementation on Ethereum Sepolia that combines rotating ECDSA keys with SPHINCS+C10 or ML-DSA-44 signatures using a Safe 2-of-2 architecture, while preserving a stable wallet address and familiar seed-based experience.
We'll examine the design tradeoffs, recovery and usability challenges, and why preparing wallets for quantum computers is also an opportunity to fix the single-factor security model we've relied on for too long.
