The First Quantum-Safe Cross-Chain Bridge
SOQ-TEC eliminates the quantum vulnerability in cross-chain custody. Tokens bridge directly into hash-based vaults. Burns on Solana release assets on Soqucoin L1. Two patents. Both proven with live 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.
| Capability | Winternitz Vault | Project 11 | Bitcoin BIP 360 | SOQ-TEC |
|---|---|---|---|---|
| Multi-use vault (16+ sigs) | ✗ Single-use | ✗ No vault | ✗ Proposal only | ✓ 16–1,024 |
| SPL token custody | ✗ SOL only | ✗ N/A | ✗ N/A | ✓ Any SPL |
| Direct-mint-to-vault | ✗ | ✗ | ✗ | ✓ Patent Claim 2 |
| On-chain WOTS+ verification | ✓ | ✗ | ✗ | ✓ + Merkle proof |
| Bridge integration | ✗ | ✗ | ✗ | ✓ Atomic CPI |
| Key reuse prevention | N/A (single use) | ✗ | ✗ | ✓ On-chain enforced |

Patent Claims — All Proven On-Chain
| Claim | Patent | What It Proves | Evidence |
|---|---|---|---|
| ✓ Claim 1 | #64/035,857 | XMSS-Lite on-chain — Merkle root commitment + WOTS+ signature verified inside Solana VM | Explorer → |
| ✓ Claim 2 | #64/035,857 | Direct-Mint-to-Vault — bridge mints SPL tokens into vault ATA via CPI, zero Ed25519 wallets | Explorer → |
| ✓ Claim 4 | #64/035,857 | Hybrid bridge — L1 lock → Solana mint → vault → WOTS+ withdrawal, full E2E verified | Bridge Program → |
| ✓ QE Claim | #64/035,873 | Quantum Express — burn 50 pSOQ on Solana devnet, relayer detects, releases 49 SOQ on L1 signed with ML-DSA-44 | L1 Release TX → |
| ✓ Security | #64/035,857 | On-chain key-reuse prevention — monotonic leaf_index enforced; attempted reuse returns LeafIndexMismatch | Vault Program → |
E2E Pipeline — All 10 Steps Verified
Two bridges. Both proven with real, verifiable on-chain transactions.
- Step 1–2 Keygen + bridge state verify — 16 WOTS+ keypairs generated, 2-of-3 threshold active
- Step 3 Vault opened — XMSS PDA created with Merkle root on-chain Explorer →
- Claim 2 Direct mint — 4,995 pSOQ minted into vault ATA, zero Ed25519 wallets Explorer →
- Claim 1 WOTS+ withdrawal — 1,000 pSOQ withdrawn with quantum-safe signature + Merkle proof Explorer →
- Step 6 Key reuse rejected — reuse of key #0 returns LeafIndexMismatch
- Step 7 Revolving withdrawal — second withdrawal with key #1 proves multi-signature capability
- Step 1 Circuit breaker active — pause_bridge returns AnchorError: BridgePaused, safety system verified
- Step 2 Bridge resumed — resume_bridge re-enables operations
- QE Claim Burn on Solana — 50 pSOQ burned on Solana devnet; relayer release recorded on Soqucoin L1 L1 Release TX →
- QE Claim Release on L1 — relayer detects burn, releases 49 SOQ on Soqucoin Testnet3 signed with ML-DSA-44 L1 TX →
