Description
Self-custodial FHE wallet. Wrap ERC-20s into confidential tokens, private sends, NixBot assistant, and dApp support on EVM testnets. NixWallet is a self-custodial browser extension for confidential asset flows, powered by Fully Homomorphic Encryption (FHE) through the Fhenix coFHE stack on supported EVM networks. CONFIDENTIAL TOKENS Wrap native ETH and ERC-20 tokens into confidential FHERC20 variants (for example, ETH to cETH and USDC to cUSDC). Confidential balances and transfer amounts are handled as encrypted values on-chain, with user-controlled reveal and decrypt flows. SEND & RECEIVE Send and receive native ETH and ERC-20 tokens publicly, and execute confidential transactions for shielded assets—including private native cETH sends where the network wrapper is deployed. NIXBOT — CONVERSATIONAL ASSISTANT NixBot is a built-in natural language assistant that parses plain-text commands into on-chain actions. Type what you want and NixBot handles the rest—including address book lookups, balance checks, and guided confirmations before any transaction executes. Supported commands: send [amount] [token] to [name or 0x...] · private send · wrap · unwrap · claim all · reveal private balance · check balance · switch network FHERC20 WRAPPER REGISTRY Uses an on-chain factory/registry that deploys a confidential wrapper the first time a token is wrapped. After deployment, all users share that same wrapper for the token. BATCH CLAIM Supports claiming multiple pending unshield requests in one transaction to reduce operational overhead. MULTI-ACCOUNT HD SUPPORT Manage multiple BIP-44 derived accounts from one seed phrase, and import external private keys. Switch accounts quickly within the interface. SECURITY • AES-256-GCM encrypted vault with PBKDF2 key derivation (600,000 iterations) • Configurable auto-lock timer (5, 10, or 30 minutes) • Password-protected mnemonic reveal with auto-hide behavior • Local-first architecture with no centralized backend; data is stored securely in browser storage. SIDE PANEL EXPERIENCE Runs in the browser's side panel for a persistent experience while browsing dApps and websites. DAPP PROVIDER & APPROVALS Injects an EIP-1193/EIP-6963 compatible provider so dApps can connect and request signatures/transactions. Sensitive actions (connect, sign, typed data, send transaction, network switch) are approved with unlock-gated confirmation. Includes support for standard v2 dApp connection flows and session request handling. ACTIVITY TRACKING Activity history includes native transactions as well as injected dApp submissions, with decoded labels for common token and wrapper flows. COMPANION DAPP & OPEN SOURCE A hosted reference dApp is available to demonstrate full integration for external developers. The entire codebase is fully open source and verifiable on GitHub. NETWORKS Currently supports Ethereum Sepolia, Base Sepolia, and Arbitrum Sepolia powered by Fhenix FHE.
