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. It does not hold user funds or keys and does not operate custody, bridging, conversion or redemption services for the public. Everything below was demonstrated on Solana devnet and Soqucoin stagenet with test tokens during the Colosseum Frontier 2026 hackathon (April to May 2026). There is no live deployment. 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.
Soqucoin Operations for Quantum-Tolerant Ecosystem Custody
Post-quantum custody software for the assets a licensed custodian holds.
100% of Solana wallets are quantum-vulnerable.
Every Ed25519 public key is exposed directly on-chain. When a cryptographically relevant quantum computer runs Shor's algorithm, every keypair is recoverable. The "harvest now, decrypt later" (HNDL) attack means adversaries are already recording Solana transactions for future decryption.
$180B+ in Solana TVL is protected by classical cryptography that has an expiration date.
Project Eleven — Solana's own PQ security partner — proved this in April 2026: replacing Ed25519 with Dilithium on Solana's testnet caused a 90% throughput reduction. Signatures went from 64 bytes to 2,420 bytes (40× larger). Solana's architecture (Gulf Stream, Turbine, QUIC) is optimized for compact data — full PQ migration would destroy what makes Solana valuable.
The Winternitz Vault was the interim answer — hash-based one-time signatures. But it handles SOL only (no SPL tokens), keys die after one use, and it can't compose with DeFi. It's a fire exit, not a home.
SOQ-TEC is post-quantum custody and settlement software that a licensed custodian can deploy for Solana assets.
Soqucoin is a purpose-built, ML-DSA-44 (FIPS 204) Dilithium-native L1 blockchain designed from genesis for post-quantum safety. It's not fast — it's Dogecoin-speed (~1-minute blocks, UTXO model). And that's the point.
The three parts:
- Solana is the trading floor (fast, liquid, classical signatures)
- Soqucoin is the post-quantum settlement layer (ML-DSA-44; the L1 was audited by Halborn)
- SOQ-TEC is the software that moves value between the two chains when a licensed operator runs it
The software does not take value from Solana. It gives a custodian a post-quantum place to hold Solana-side value.
Flow the software implements. Custody sits with the operator's vault keys.
Solana Wallet (Ed25519, vulnerable)
→ Winternitz Vault (hash-based PQ on Solana)
→ SOQ-TEC Bridge (relayer attestation)
→ Operator's vault (ML-DSA-44 keys on Soqucoin L1)
→ Return path to Solana (operator's program mints the Solana-side token)

The XMSS vault is the primary path — an end-to-end quantum-safe chain where Ed25519 is used ONLY for Solana transaction fees, never for value custody:
- User generates an XMSS-Lite key tree (Keccak256 WOTS+, w=16)
- Vault program verifies WOTS+ signature + Merkle proof on-chain
- Vault CPI-calls
burn_for_redemptionon the bridge program - Relayer detects the burn event (identical to native burns)
- The operator's ML-DSA-44 signer releases SOQ on L1
Value custody chain: WOTS+ (Keccak) → ML-DSA-44 (Dilithium) — zero classical touch.
SoquShield (Flutter iOS/Android) includes a complete Dart port of the XMSS-Lite signing engine:
wots_signer.dart— WOTS+ sign/verify, hash chainsxmss_tree.dart— key tree + Merkle proof generatorvault_bridge_service.dart— Solana TX builder with PDA derivation, Borsh encoding- Cross-verified bit-for-bit against the JavaScript implementation (9/9 vectors match)
The terminal is a demonstration dashboard that showed test-network data during the hackathon. It uses a retro CRT terminal aesthetic:
- Boot Sequence — BIOS-style system initialization
- Vault Status — Vault balance and backing ratio panels (test data)
- Network Comparison — Soqucoin (PQ-NATIVE) vs Solana (QUANTUM EXPOSED)
- Bridge Activity — Transaction feed (test data)
- Proof of Reserves — SOQ locked vs pSOQ minted panel (test data)
- CRT Effects — Scanlines, vignette, phosphor glow, screen flicker
