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 · Custody and settlement software
Post-quantum custody and settlement software for regulated operators.
SOQ-TEC is post-quantum custody and cross-chain settlement software for regulated custodians, exchanges and issuers, who operate it under their own licences. Labs demonstrates it on test networks only. Assets are held in hash-based vaults secured by ML-DSA-44 signatures. Two patent applications cover the design, both demonstrated with test-network transactions. pSOQ is a token on Solana. The one-time migration to SOQ closed on 5 October 2026 and was committed in block 1 of mainnet; pSOQ is not a wrapped or redeemable form of SOQ.

§ 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.”

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 and auditable. The full pipeline (key generation, relay, vault, WOTS+ withdrawal, key-reuse rejection) is demonstrated with verifiable test-network transactions.
§ 04 — For the Solana ecosystem
SOQ-TEC gives licensed custodians post-quantum custody technology for Solana assets.
