Reading the canary…

Lifeboat

Your wallet signs with Ed25519, which a large quantum computer can break. A Lifeboat key is hash-based (LM-OTS), made in this browser, and only its fingerprint goes on-chain. After Q-day, recovery uses the last snapshot before the canary tripped and this key, not your wallet.

Your key, as it is built

0 / 26 hash chains · 255 steps each

Each row is one Winternitz chain: a secret hashed 255 times. The end of every chain feeds the public key.
