A hash-based keypair that lives behind your Solana wallet. Its public key is a single Merkle root; its address is a hash of that root. Like a never-spent Bitcoin address, nothing about it is exposed until you sign, and every key signs exactly once.
Your wallet signs a fixed message. Its deterministic signature seeds 256 Winternitz one-time keys, hashed into a Merkle tree in this tab. Secrets never leave the browser and are forgotten when you close it.
pqc.market — Post-Quantum Identity Derivation v1 Signing this message derives your hash-based (WOTS/XMSS) keys locally in your browser. It is not a transaction and costs nothing. Never sign this exact message on any other site. Wallet: <your wallet> Domain: pqc.market Version: 1
