The First Quantum-Safe Vault on Solana
SOQ-TEC eliminates the quantum gap in cross-chain custody. Bridge tokens directly into hash-based vaults — no Ed25519 wallet ever touches your assets. All proven on Solana devnet with verifiable on-chain transactions.
Nothing Like This Exists
The only quantum-safe vault on Solana handles 1 signature and SOL only. We built the next generation.

Patent Claims — All Proven On-Chain
Patent Application #64/035,857 — XMSS-Lite Revolving Vault
XMSS-Lite on Blockchain VM
Full Merkle tree commitment with on-chain leaf index enforcement and WOTS+ signature verification — the first stateful hash-based signature scheme executing inside a smart contract.
View on Explorer →Direct-Mint-to-Quantum-Vault
Bridge mints SPL tokens directly into the vault's ATA via CPI. Tokens never touch an Ed25519 wallet — the quantum-breakable gap is eliminated entirely.
View on Explorer →Hybrid PQ Bridge + Hash-Based Custody
End-to-end flow: L1 lock → bridge mint → quantum vault → WOTS+ withdrawal. Classical bridge infrastructure composing atomically with post-quantum custody.
View Bridge Program →On-Chain Key Reuse Prevention
Monotonic leaf_index enforced at the smart contract level prevents catastrophic WOTS+ key reuse. Attempted reuse returns LeafIndexMismatch — proven in the E2E demo.
View Vault Program →Verified On Solana Devnet
Every step of the E2E pipeline is a real, verifiable Solana transaction.
Key Generation + Bridge Verify
16 WOTS+ keypairs generated offline. Bridge state verified: 2-of-3 threshold active.
Direct Mint to Vault
4,995 pSOQ minted directly into vault ATA. Zero Ed25519 wallets.
Explorer →WOTS+ Withdrawal
1,000 pSOQ withdrawn with quantum-safe WOTS+ signature + Merkle proof.
Explorer →Key Reuse Rejected
Attempted reuse of WOTS+ key #0 rejected with LeafIndexMismatch.
Revolving Withdrawal
Second withdrawal with key #1 — proves multi-signature vault capability.
Weekly Progress Demos
Four weeks of building — from terminal dashboard to fully verified quantum vault.

Direct-Mint-to-Vault E2E
Full 7-step pipeline: key gen → bridge → vault → WOTS+ withdraw → key reuse rejection.
