Quantum Expressproven on-chain
Direct-mint-to-vault routing — tokens flow straight into a post-quantum vault rather than sitting in an exposed bridge wallet.
SOQ-TEC · Cross-chain custody
Cross-chain custody, quantum-safe.
SOQ-TEC routes assets into hash-based vaults secured by post-quantum signatures. Burn pSOQ on Solana; release SOQ on Soqucoin L1. Two patents, both proven with live on-chain transactions.

§ 01 — Why bridges fail
Cross-chain bridges concentrate enormous value behind a small set of signing keys — and that signing layer is where they break. On top of that, the classical signatures protecting them have a quantum expiry date.
SOQ-TEC hardens both: assets route into hash-based vaults, signatures are post-quantum, withdrawals are one-time (WOTS+), and key reuse is rejected by construction.
“The code is open. The proofs are on-chain. Verify everything.”
§ 02 — How it works
- Relayer
- Custom 3-of-5 Dilithium · not a classical multisig
- Vaults
- Hash-based · post-quantum by construction
- Withdrawals
- WOTS+ one-time signatures · key reuse rejected
- Peg
- pSOQ : SOQ = 1 : 1 · burn on Solana, release on L1
- Wallet
- SoquShield · manages Solana pSOQ and L1 Dilithium keys

XMSS revolving-key vaultproven on-chain
A hash-based, one-time-key withdrawal scheme that rejects key reuse — the failure mode that the only prior quantum-safe Solana vault couldn’t cover at scale.
Open source & auditable. The full pipeline — key generation → bridge → vault → WOTS+ withdrawal → key-reuse rejection — is demonstrated with real, verifiable on-chain transactions.
§ 04 — For the Solana ecosystem
SOQ-TEC brings quantum-safe custody to one of the largest token ecosystems in crypto. The prior state of the art handled a single signature and SOL only; SOQ-TEC is built for the next generation.
