Qryptic. The post-quantum harden layer for crypto.

Introduction

Qryptic is the post-quantum cryptography layer for crypto. It is a hybrid classical plus lattice signature and verification layer that retrofits existing wallets, contracts, and bridges so they survive Q-day in place, without migrating to a new chain. Built on the finalized NIST standards: FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA). Launching on Virtuals (Base).

This document is engineering-first. It describes the threat, the lane Qryptic occupies, the mechanisms in design, the token, and the roadmap. No countdown, no doom. Protection and readiness.

The problem

The standards fight is over. NIST finalized the post-quantum signature standards in 2024. What is left is migration, and every chain is solving it alone.

Citi research puts roughly $450B in addresses with already-exposed public keys, primarily reused keys and legacy script types where the public key is visible on-chain today. Google's 2026 paper models a ~9 minute private-key recovery window once a signing key is in the mempool, with a roughly ~41% probability of a successful hijack under modeled conditions.

Per-chain reality: Bitcoin has contentious legacy-coin freeze proposals. Ethereum has multiple competing fork directions. Bridges have no migration story at all. Each ecosystem is solving this once, in isolation, on its own clock.

How Qryptic works

Four capabilities, one retrofit layer. None of them require a new chain.

Hybrid signatures. Classical plus lattice ML-DSA on a 1-of-2 signer. Existing classical paths stay valid today. The lattice path becomes the quantum-safe path at flip-the-switch. Either signature verifies. No flag day, no fork required for adoption.

Cross-chain migration rails. Qryptic is a layer over existing chains. Wallets and contracts add PQ verification in place. No new chain to migrate to, no liquidity fragmentation.

Bridge protection. Bridges are the sharpest wedge: large value, custodial trust, no PQ migration plan. Qryptic adds lattice attestations to bridge messages first.

Cost-aware on-chain verification. Naive ML-DSA verify is expensive on-chain because PQC signatures are larger ( ~3309 B for ML-DSA-65, ~4627 B for ML-DSA-87). Qryptic uses aggregation and SNARK-style compression so per-transaction cost stays usable in production.

Where Qryptic fits

Existing post-quantum projects are siloed new L1s that ask you to move. That is migration on top of migration. Coinbase's advisory board flagged the fragmented per-chain planning and endorsed hybrid 1-of-2 signing as the practical path forward.

Unified, cross-chain, retrofit-the-existing-ecosystem is our lane. Bridges first, where the gap is sharpest. We complement the L1s, we are not a rival chain.

$QRYPT

$QRYPT is the utility unit of the harden layer. Three functions, no more.

Protect. Pay $QRYPT to harden a wallet, contract, or bridge. The payment adds lattice attestations to the protected asset.

Verify. Validators stake $QRYPT to attest a migration is quantum-safe. Honest attestations earn. False attestations are slashed.

Govern. Parameter votes on the migration standards, supported algorithms, verifier costs, and which chains and bridges go first.

Launching on Virtuals (Base). No wallet connect. No tokenomics page.

Roadmap

Migration as engineering, not as countdown. No hard dates.
