Post-quantum and privacy
infrastructure for blockchains
NixProtocol is a parent brand with two products. PQ Chain is the lattice-native settlement rail built post-quantum from genesis, for tokenized assets, central-bank pilots, and regulated issuers. NixPay extends the stack with zero-knowledge privacy on every EVM chain, today, while the post-quantum migration arrives.
Two products. One stack.
PQ Chain: Lattice-native settlement rail built post-quantum from genesis. HAWK-512 signatures, Ring-SIS state commitments, LatticeFold-style block proofs. Testnet alpha live, open for design partners.
NixPay: Zero-knowledge privacy for ERC-20 transfers on every EVM chain. UTXO notes, UltraHonk proofs, NixAddress. The bridge product for buyers who want privacy on existing chains today while planning the post-quantum migration.
Both products run on one cryptographic stack and include auditor access for regulatory compliance.
Our Values
The principles that guide everything we build.
Privacy by Default
We believe privacy is a fundamental right. Our technology makes confidentiality the default, not an afterthought.
Flexible by Design
Reference implementation for quick integration, enterprise engagements for unique needs. We meet you where you are.
Migration-Ready
PQ Chain ships post-quantum from genesis. NixPay delivers privacy on EVM today and swaps in PQ primitives without architectural rewrite. We do not lock you into a chain or a moment.
Open Standards
Built on published research: UltraHonk and Noir for NixPay's zero-knowledge proofs, the NIST PQC family and LatticeFold algebra for PQ Chain's lattice stack. Trust is verified on-chain, not asserted.
Our Journey
Foundation
Core circuits (deposit, transact, registration) implemented and tested. Smart contracts deployed on testnets. SDK with full witness building, proof generation, and note management. Relayer with gas abstraction and Chainlink fee oracle. Web app with in-browser proving. MCP server for AI agent integration. Auditor decryption dashboard.
Partner Validation
CURRENTOnboard first integration partners for pilot deployments. Launch partner pilot on testnet. Complete security audit and publish report. Launch on production mainnet.
Milestone: First partner live on mainnet
Cosmos Privacy Modules
Build Cosmos SDK privacy modules (deposit, transfer, withdraw) for appchain integration. Port ZK verification to Cosmos execution environment. Implement IBC-compatible note commitments and nullifier tracking. Privacy module registry for appchains to opt in to shared or isolated privacy pools. Documentation and integration guides for Cosmos appchain developers.
Milestone: First partner live in production on EVM
Private Agent Registry
On-chain identity system for AI agents with privacy-preserving registration. Agents register NixProtocol identities without revealing controlling wallets or operators. Verifiable agent credentials to prove capabilities or authorizations without revealing identity.
Milestone: Cosmos modules deployed on at least one appchain
Private Agent Transactions
Agent-to-agent private transfers through the shared pool. SDK and MCP tooling for autonomous deposit, transfer, and withdrawal. Gas abstraction via relayer so agents transact without holding native tokens. Programmatic privacy workflows for autonomous treasury management, payments, and settlements.
Milestone: Agent registry live
