Bind a post-quantum key to your Bitcoin address
Generate a post-quantum key, sign a binding message with your Bitcoin wallet, and anchor the pair on-chain. It is a public, timestamped, verifiable record that both are yours — an open registry, not a company's private one. The same key already secures a PQWeave EVM account and Solana vault, so this is one post-quantum identity across all three. It records intent and ownership; it does not by itself make your Bitcoin quantum-safe.
Live on a public EVM testnet. Run a real one-transaction migration with test funds — no real value at risk while the contracts finish their audit.
Migration works on any EVM chain and any EVM wallet. Non-EVM chains (Bitcoin, Solana, and more) can't be migrated in-protocol — scan one to see its options.
1 · Generate your post-quantum key
Choose a password, then generate a hash-based (Lamport + Merkle) post-quantum key in your browser. The key is created from fresh randomness, encrypted with your password (AES-256-GCM), and downloaded as a file. The raw secret is never displayed.
2 · Sign with your Bitcoin wallet
Save your post-quantum key above first.
3 · Anchor it on-chain
The attestation registry is not deployed in this environment yet. Your key and signature are valid — anchoring will be available once the contract is live.
Honest scope: this binds and timestamps your key and address. It does not make Bitcoin quantum-safe — only a protocol upgrade can. It prepares you for a future migration path and proves ownership today. See the Bitcoin exposure breakdown.
