Privacy
Infrastructure
for EVM Chains
Modular privacy infrastructure powered by zero-knowledge proofs. Integrate, deploy, or customize your applications for privacy with any ERC-20 token on any EVM chain.
Testnet live on Avalanche Fuji & Base Sepolia. Open for integration.
Build with Nix Primitives
Add privacy to your app with modular building blocks. ZK proofs, private identities, and encrypted transfers ready to integrate.
ZK Proof Engine
Generate ZK proofs to add private transactions, hidden balances, or confidential logic to your app without revealing user data on-chain.
NixAddress Identity
Give your users private identities with NixAddress. They transact using a privacy key instead of exposing their real EVM address.
AI Agent Toolkit
Plug the MCP server into any AI agent to enable private payments, balance checks, transfers, and withdrawals through natural language.
Any EVM Chain
Deploy the same privacy primitives on any EVM chain. Build once, add privacy everywhere. Currently live on Avalanche Fuji and Base Sepolia testnets.
Compliance Ready
Ship privacy features with regulatory confidence. A designated auditor can decrypt transaction details, so your app stays compliant by default.

How Teams Use NixProtocol
Private Treasury Operations
Deposit ERC-20 tokens into the privacy pool and manage treasury without exposing holdings or transaction patterns.
Confidential Payroll
Process compensation via UTXO notes without revealing individual salaries on-chain. Only the auditor can decrypt amounts.
Private Transfers
Send ERC-20 tokens privately using 2-in/2-out UTXO transfers. Sender, recipient, and amounts remain hidden.
Relayer Gas Management
ZK proofs authorize transactions instead of signatures, enabling relayers to handle gas on behalf of users. Customize gas fees with our infrastructure.
Cross-Border Settlements
Execute international transfers with private amounts and recipients while maintaining auditor-level compliance.
Note Consolidation
Merge multiple UTXO notes into one without revealing balance history. Simplify your private holdings.
Built for EVM Ecosystem
Privacy infrastructure for applications building on EVM-compatible chains.
DeFi & Payment Apps
Integrate NixProtocol's privacy infrastructure into payment apps and DeFi protocols on any EVM chain. Customizable with compliance-ready auditor access.
Institutional Custodians
Deploy private asset management infrastructure with confidential settlement and auditor-verifiable proof of reserves. Customizable for your compliance needs.
Enterprise Treasury
Build confidential payroll, vendor payments, and cross-border settlement workflows on top of NixProtocol's privacy layer. Auditor key enables transaction-level disclosure on demand.
