A confidential wallet powered by Fhenix—wrap tokens into FHERC20, send encrypted transfers, and decrypt balances with coFHE. Connect external sites via EIP-1193 / EIP-6963 or WalletConnect. Includes NixBot, a conversational assistant that executes on-chain actions from plain English. Try the hosted companion dApp for a full integration demo.
NixWallet wraps Fhenix FHE into a browser extension—encrypted balances, multi-network testnets, in-wallet dApp approvals, and a companion dApp that shows how any external site can integrate.
Seamlessly wrap any ERC-20 token into a fully homomorphic encrypted variant. Your balances and transactions remain confidential on-chain.
Derive unlimited HD accounts from a single seed phrase, or import external private keys. Switch between wallets instantly.

A text-based transaction assistant embedded in NixWallet. Skip the forms — type what you want in plain English and NixBot builds, previews, and submits the transaction for you.
NixBot is a text-based transaction engine built into the wallet's side panel. Type a command like "send 10 cUSDC to Alice" and it parses your intent, resolves contact names to on-chain addresses, estimates gas fees, and presents a ready-to-sign transaction — no forms, no dropdowns, no manual address entry.
We built a browser extension wallet and a hosted companion dApp to make confidential Fhenix flows feel familiar in the browser—wrap public tokens, send encrypted amounts, unwrap, and claim—while proving that any external site can connect through the same provider without shipping a second signing UI.
The companion at nixwalletdapp.vercel.app exists so developers can copy a real integration on Ethereum Sepolia, Base Sepolia, and Arbitrum Sepolia with Fhenix FHE, and so judges and users can try the full path in one click.
Connect from the site, approve in the NixWallet side panel, and walk through wrap →
confidential send → unwrap → claim. The companion never holds keys—it only calls eth_* on the injected provider.
The companion dApp never stores private keys or shows trusted transaction modals. It only calls the provider; NixWallet owns every approval.
