Post‑quantum custody software for Solana and Bitcoin settlement.
Solana wallets rest on Ed25519. Bitcoin rests on secp256k1. Both are classical signatures that a sufficiently large quantum computer breaks, and both can be harvested today for decryption later. SOQ-TEC is post-quantum custody and cross-chain settlement software for regulated custodians, exchanges and issuers, who operate it under their own licences. It has a Solana reference lane and a Bitcoin reference lane. Soqucoin Labs demonstrates it on test networks only.
The Solana lane.
Quantum Express optimistic settlement and the XMSS Revolving Door vault: two patent-pending technologies, demonstrated before mainnet on Solana devnet and the Soqucoin test network. 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.
The Bitcoin lane.
BTCSOQ: a reference implementation of Bitcoin-backed receipts for licensed custodians. The July 2026 demonstration on testnet4 minted ML-DSA-44 receipts, settled them into USDSOQ test tokens and paid machines over L2SOQ. Every event was signed and can be verified in your browser.
Both lanes were demonstrated on test networks with test coins. Soqucoin Labs operates no live deployment; licensed operators run the software under their own licences. What the demonstrations show is the shield: once value is held under ML-DSA-44, taking it means forging a NIST post-quantum signature.
