Rabby Wallet

Rabby Wallet is an open-source browser extension wallet developed by DeBank Global Pte. Ltd., focused on Ethereum and EVM-compatible blockchains. It supports over 130 networks including Ethereum, Avalanche, Polygon, BNB Smart Chain, Arbitrum, Optimism, Base, zkSync, and Linea. The extension automatically detects which chain a connected dApp uses and switches to the matching network, removing the manual chain-switching step that multi-chain browsing typically requires. This auto-detect behavior reduces friction when moving between layer 2 networks, sidechains, and Ethereum mainnet during a single session.

Rabby’s security model centers on a pre-sign security engine that simulates each transaction before the user signs. Users see estimated balance changes, contract approvals, and a risk score for the address or contract they are about to interact with. The wallet flags suspicious contracts, scam tokens, and known phishing addresses based on a continuously updated risk database. Token approvals are visualized so users can spot unlimited-allowance requests before signing, and a built-in approval manager allows revoking past permissions. The full codebase is published on GitHub under the RabbyHub organization, and the project undergoes independent security audits with reports made public.

Rabby supports multiple signing flows. Hardware wallets including Ledger, Trezor, OneKey, and Keystone connect through USB or QR-code. Watch-only mode lets users monitor any address without importing private keys. Smart-contract wallets like Safe (formerly Gnosis Safe) and WalletConnect-compatible mobile wallets such as imToken and TokenPocket are also supported. A built-in address book stores frequently used contacts and applies an internal whitelist for high-value transactions. The integrated swap interface aggregates rates from multiple DEX aggregators, and a fiat on-ramp powered by third-party providers is available for direct purchases.

Rabby is available as a Chrome extension compatible with Chromium-based browsers, and as a mobile app for both iOS and Android. Private keys are encrypted locally and never transmitted to DeBank’s servers.
