Quantum Vault by Project Eleven provides sensible quantum security on Bitcoin & Ethereum today.
Built for the quantum era, Quantum Vault keeps BTC and ETH protected behind hash functions, monitors for public key exposure, and warns you when a vault becomes vulnerable.
Quantum Vault is a practical first step to reduce exposure today while the ecosystem moves toward full post-quantum security.
This is a reference implementation rather than a production wallet. The code has been audited by Cure53.
