What Rabby Wallet is

Rabby Wallet is a free wallet for digital assets on Ethereum and EVM-compatible networks. It stores assets locally, connects to decentralized applications, displays blockchain addresses and network information, and broadcasts transactions. Users can swap assets through third-party Dapps; those services may charge fees, and Rabby says displayed swap prices are estimates that can change. Before signing, Rabby scans transactions for threats such as inactive recipient accounts or contracts with known vulnerabilities, then summarizes expected downstream effects. Its extension maps DeFi websites to associated chains and selects a chain automatically, while allowing users to change that choice. Rabby offers extensions for Chrome, Brave, and Edge; apps for iPhone, iPad, and Android; and desktop downloads for macOS and Windows. The project is open source on GitHub and lists audits by SlowMist and Least Authority. Integration documentation covers JavaScript and several Web3 libraries. RabbyKit supports React, Vue, other frameworks, and EIP-6963 wallet selection. Extension private keys are stored locally and encrypted with AES-GCM using a password-derived key.
