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, two of NIST's finalized 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 finished its post-quantum signature standards. Claak builds on SPHINCS+ (SLH-DSA, FIPS 205) and Falcon (FN-DSA, FIPS 206), both designed for exactly this job.
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 built on NIST's finalized standards: SPHINCS+ (SLH-DSA, FIPS 205) on Base and Falcon (FN-DSA, FIPS 206) on Solana. Not an ECDSA or Ed25519 key that a future quantum computer could break.
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, and USDC on Base and Solana. 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. Team treasuries, payments, and payroll are built on the same post-quantum foundation, not sold as separate products.
Browser-extension wallet on Base and Solana testnets. Post-quantum smart accounts are live, with swaps and dApp connections working. Join the tester program.
Base mainnet and SPHINCS+ standard accounts are built and already running in our own testing. They open to everyone once backup and restore are proven and the contracts are verified. Early days, so start small.
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.
