Claak is a self-custodial crypto wallet where your funds are controlled by a post-quantum key, checked on-chain. It is built on SPHINCS+ and Falcon, the two designs behind NIST's post-quantum signature standards. Every other wallet depends on keys a future quantum computer could break. Yours shouldn't.
Every crypto wallet today secures funds with ECDSA or Ed25519 signatures. A sufficiently large quantum computer breaks both.
Attackers can copy public keys from the blockchain now and break them later. Your funds do not need to move for the risk to begin.
NIST has standardised hash-based signatures as SLH-DSA (FIPS 205), with the lattice-based FN-DSA still in draft. Claak builds on the same two designs, SPHINCS+ and Falcon, adapted so a chain can actually afford to verify them.
Blockchains cannot change their signature schemes overnight. Claak's smart accounts check post-quantum signatures on-chain today, with no protocol change needed.
Post-quantum security underneath, everyday wallet on top. Send, swap, and connect to dApps like you always have.
Your funds are controlled by a post-quantum key: a keccak-based SPHINCS+ variant on Base and Arbitrum, Falcon on Solana. Not an ECDSA or Ed25519 key that a future quantum computer could break. Both are the designs behind NIST's post-quantum signature standards, tuned for on-chain cost rather than run as the certified parameter sets.
Your account is a smart account that checks the post-quantum signature on-chain for every operation. Classical keys only carry transactions. They cannot spend your funds.
ETH, SOL, USDC, and BTC across Base, Solana, and Bitcoin. Create a new wallet or restore one from a standard recovery phrase.
Swap tokens on Base right from the wallet. Trade instantly, or spread the swap over time with TWAP.
Claak speaks the standard wallet protocol (EIP-1193), so existing dApps just work. Pick your post-quantum vault or a standard account for each dApp.
Keys are created and stored only on your device, encrypted with your password. No accounts, no analytics, no server.
Optional Touch ID or Windows Hello unlock on top of your password-encrypted vault.
Export and import an encrypted backup file, plus a standard recovery phrase. You can restore your wallet on any device.
SPHINCS+ for standard security, Falcon-1024 for maximum. Post-quantum safety is the default for every user. It is free, with no premium tier.
Claak starts as a wallet. Payments and payroll are features of it rather than separate products. PQ SAFE, the post-quantum multi-sig for treasuries, is its own product on the same account core, and is still at design stage.
The browser extension runs on Base mainnet, with post-quantum smart accounts, swaps and dApp connections working on real funds. Solana and Bitcoin are on testnet. The contracts are unaudited, so start small.
The contracts are deployed but unaudited, and an external audit is the next thing that matters. Arbitrum is pre-wired and waiting on a deploy, and Solana needs Falcon-1024 before its maximum tier can exist.
A post-quantum multi-sig for teams and treasuries. Every multi-sig treasury today sits on classical keys. PQ SAFE is the quantum-safe successor.
Batch payments, recurring payments, and payroll for freelancers, teams, and businesses. These are features of the wallet, not a separate product.
