Public blockchains have a privacy problem
The same feature that makes them trustworthy makes them operationally hazardous.
Every transaction you broadcast is permanent public data. Wallet addresses become identities. Transaction histories become intelligence. Privacy is sacrificed for decentralization.
Users, protocols, DAOs, and exchanges have responded by managing tens or hundreds of wallet addresses. One wallet for payroll. Another for vendor payments. A third for customer transactions. This operational complexity increases the risk of mistakes and adds friction to every operation.
The situation intensifies as blockchain enters mainstream finance. Real-world asset tokenization, business procurement, and regulated financial operations require confidentiality. Regulators demand compliance. Businesses demand privacy. Public blockchains offer neither without compromise.
The failed solution: privacy chains
Existing privacy solutions focus on creating new privacy-enabled Layer 1s or Layer 2s. Monero and Zcash are the most prominent examples.
These solutions trade one problem for two larger ones. The new chain is often less distributed and less censorship-resistant than established networks. All liquidity must migrate to the new chain, which has proven difficult or impossible.
You lose the security guarantees of Ethereum or Avalanche. You lose access to existing liquidity and ecosystem maturity. You gain privacy by abandoning the infrastructure that made blockchains valuable in the first place.
NIX Protocol: privacy where you already are
That's why we built NIX Protocol - a lightweight set of smart contracts that runs on any public EVM chain. It gives users the ability to transact privately without leaving the chains they already use.
You keep the censorship resistance of Ethereum. You keep the liquidity of Avalanche. You keep your existing custody setup. You add privacy through cryptography.
The protocol uses zero-knowledge proofs and encryption to ensure transaction proofs remain on-chain and immutable. The data cannot be read by anyone except the designated parties. You use your existing wallet on your existing chain. No fund migration required.
How it works (TLDR)
The complexity is hidden under the hood. Your operations stay simple:
Mask your identity. Connect your wallet to generate a NixAddress. This is your private, reusable payment ID.
Shield your assets. Deposit ERC-20 tokens (like USDC) into the NixPool contract. They convert into encrypted notes.
Transact privately. Send funds to any NixAddress. Zero-knowledge proofs authorize the move. Relayers handle the gas. You can transact without needing ETH or AVAX.
Exit clean. Recipients withdraw to a fresh wallet. This severs all on-chain links to the sender.

Compliance without compromise
Privacy does not mean opacity to regulators.
NIX Protocol is built for selective disclosure. Every transaction includes ECIES-encrypted data that a designated auditor can decrypt using their private key. This gives them read-only access to transaction details when legally required. The public sees nothing.
Privacy that respects regulatory requirements is the only privacy that scales.
Use cases
Privacy infrastructure enables operations that are currently impossible or impractical on public blockchains:
Confidential business payments. Pay vendors and employees without revealing individual amounts.
Private asset management. Hold and move assets without broadcasting positions to competitors.
Protected trading strategies. Execute large trades without MEV extraction or front-running.
Confidential tokenization. Issue and trade real-world assets with private metadata.
