BlindSpot

The privacy layerfor the quantum era.

Quantum vault

Quantum-safe vault · hash-based signatures

Out of reach. Even tomorrow.

SOL A QUANTUM COMPUTER CANNOT TAKE

Vault.

Park SOL and USDC behind hash-based signatures that quantum computers are not known to break. Only keys from your BlindSpot wallet can move them.

What this protects, and what it does not
  • Protected: SOL and USDC inside the vault, even from someone able to forge normal Solana signatures, as a large quantum computer could. Only a SHA-256 Winternitz signature from your keys moves them.
  • USDC’s issuer (Circle) can freeze any USDC account, this vault’s included. The vault guards your access, not USDC itself, and a frozen USDC withdrawal pauses the whole vault until it is unfrozen.
  • Every key signs only once: two different withdrawals from one key would let someone forge a third, so each signed withdrawal is saved and re-sent until it lands.
  • Not covered: SOL elsewhere, your private balance, and Solana itself, which uses ed25519 until it upgrades.
  • Open source, self-reviewed, no third-party audit. Program: 9Pj3…Z542 ↗, code hash a0fc1ff09b666818… (rebuild it from vault/ to check)

THE POINT OF BLINDSPOT

Privacy is room
to be yourself.

An open blockchain shouldn’t mean an open book. BlindSpot brings private payments and confidential compute into one place.

Separate your activity

Shield funds in a shared pool. Private payments come from that pool instead of directly from your wallet.

Keep your thoughts yours

Confidential compute uses encrypted requests and attested hardware to protect your prompts and responses.

Check for yourself

Verify shared payment and compute proofs in your browser. No connected wallet required.

Privacy has boundaries. Deposits are on-chain, and recipients can see the payments they receive. Each tool explains what its proof can verify.

Connect

BlindSpot wallet

No extension, no app: a wallet made and kept in this browser, locked with your password.

Or your own wallet
