Privacy Infrastructure
for Ethereum & L2s
NixProtocol gives developers modular privacy primitives for EVM chains. Add private deposits, transfers, and withdrawals to your app with ZK proof authorization and built-in auditor compliance. Live on Avalanche Fuji & Base Sepolia testnets.
Two Ways to Work With Us
Privacy Pool Protocol: UTXO-based privacy pool for private ERC-20 transfers with ZK proof authorization. Deposit, transfer, withdraw, and consolidate notes privately. Testnet live now.
Enterprise Integration: Need something specific? We build custom Noir ZK circuits and privacy solutions tailored to your exact requirements. Fixed-price engagements with dedicated support.
Both paths are built on the same cryptographic foundations 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.
Chain Agnostic
Deploy on any EVM-compatible chain. Your infrastructure, your choice. No vendor lock-in.
Open Standards
Built on proven cryptography and open standards. Trust is established through on-chain verification, formal security audits (in progress), and partner-initiated independent reviews.
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
