Zproxima Chrome extension security report

Zproxima is your confidential token companion for the Zama FHEVM ecosystem. It runs as a Chrome side panel, giving you instant access to Fully Homomorphic Encryption (FHE) powered token operations on Ethereum. KEY FEATURES • Registry Browser — Browse all ERC-20 to ERC-7984 confidential wrapper pairs registered on-chain. View token metadata, contract addresses, and registration status at a glance. • Wrap & Unwrap — Shield public ERC-20 tokens into confidential ERC-7984 wrappers or unwrap them back. The extension handles approval, wrapping, and progress tracking in one flow. • Encrypted Balance Decryption — Tap the key icon on any confidential token to decrypt your private balance using FHE. Balances stay encrypted on-chain and are only revealed locally in your browser. • Confidential Transfers — Send confidential tokens to any address. Amounts are encrypted client-side before submission, preserving transaction privacy on-chain. • Token Faucet — Claim testnet mock tokens (USDC, USDT, WETH, BRON, ZAMA) with one click for development and testing on Sepolia. • ZBot Assistant — Built-in chat assistant that answers questions about FHE, the Zama protocol, ERC-7984, and guides you through extension features. • Register Custom Tokens — Deploy new confidential wrappers for any ERC-20 token or paste existing wrapper addresses to add them to your registry. • External Wallet Support — Connect MetaMask or any browser wallet via the companion web app at zproxima.vercel.app for full wrap/unwrap/decrypt functionality. PRIVACY & SECURITY Zproxima never transmits your private keys. All cryptographic operations (FHE encryption, decryption, key generation) run locally in your browser using WebAssembly. Your wallet seed phrase and private keys are stored exclusively in chrome.storage and never leave your device. NETWORK SUPPORT Currently supports Ethereum Sepolia Testnet (Zama FHEVM). Mainnet support coming soon.
