Quantum-era privacy layer · Solana

The privacy layer for Solana, built for the quantum era. Hold SOL behind quantum-safe signatures in the Quantum vault, and move it privately with zero-knowledge proofs, all from your browser.

Two layers

Shield what you move.
Vault what you keep.

ZK shield

Live

Deposit once and your coins become sealed notes in a shared pool. Send, swap and withdraw by proof: the chain checks every move is valid without learning who made it or how much moved.

  • Groth16 proofs, verified on-chain
  • Relayers submit for you: no wallet pop-ups, no gas trail
  • Exit to a fresh address or to any chain via private routes
Shield funds

Quantum vault

Quantum-safe

A vault for SOL you plan to hold for years. The on-chain program pays out only against a hash-based signature, so its security rests on hash functions rather than the elliptic curves a quantum computer could break.

  • Opened with your BlindSpot wallet
  • Keys are created on your device and never leave it
  • Fill it from any wallet, release with your vault keys

The quantum question

Ready for the day
the maths changes.

Large quantum computers would break the elliptic-curve maths behind most of crypto. Hash functions are expected to hold. Here is exactly where each part of BlindSpot stands today.

  1. Quantum vault

    SOL is released only against a hash-based signature from your BlindSpot wallet keys.

    Quantum-safe

  2. ZK shield

    Private balances, payments and swaps, proven with Groth16 zero-knowledge proofs.

    Live

  3. Post-quantum shield

    Hash-based (STARK-style) proofs and ML-KEM note encryption for the pool.
