SOQ-TEC

SOQ-TEC is post-quantum custody and cross-chain settlement software for regulated custodians, exchanges and issuers, who operate it under their own licences. Soqucoin Labs builds and licenses the software and demonstrates it on test networks only. Soqucoin Labs operates no live deployment.

Architecture

SOQ-TEC has three parts: a wallet integration for the operator's users, a relayer the operator runs, and a hash-based vault. A licensed operator holds the vault keys and the relayer keys.

pSOQ

pSOQ is a token on Solana. The path from pSOQ to SOQ is in legal review and details will be published when it is complete.

Patent-Pending Technologies

XMSS Revolving Vault

Patent pending (Soqucoin Labs Inc.)

Traditional multi-sig vaults use static key sets. If a key is compromised, the entire vault is at risk until a manual key rotation occurs.

The XMSS-Lite Revolving Vault uses hash-based one-time signatures (built on WOTS+ leaves, in the XMSS family) that advance after each use. Every vault signature consumes a key leaf and moves to the next. An attacker who captures a signing key can use it at most once, and by the time they try, that leaf is already consumed.

Property	Traditional Multi-Sig	XMSS-Lite Revolving Vault
Key reuse	Unlimited	One-time (per leaf)
Post-compromise recovery	Manual key rotation	Advances to next leaf
Quantum resistance	No (ECDSA)	Yes (hash-based)
Signature scheme	ECDSA/Schnorr	XMSS-Lite / WOTS+ (hash-based, XMSS family)

Quantum Express

Patent pending (Soqucoin Labs Inc.)

Cross-chain transfers typically require lengthy confirmation periods (10+ minutes) to prevent double-spend attacks. Quantum Express is a proposed fast-confirmation protocol for cross-chain settlement that uses lattice-based attestations to shorten the wait. It is a design and has not shipped.

Status

SOQ-TEC is software under development. Soqucoin Labs demonstrates it on test networks only and operates no live deployment. Any production deployment is by a licensed operator under that operator's own licence.
