Rabby Wallet
A fast, user-friendly browser wallet focused on developer tools, gas optimization, and safe DeFi interactions.
What is Rabby Wallet?
Rabby Wallet is a browser extension wallet designed for Ethereum and EVM-compatible chains. It combines familiar wallet features (accounts, imports, and transaction history) with advanced DeFi-focused tooling like transaction simulation, gas optimizations, and protection against common UX pitfalls in decentralized finance.

Getting started — quick setup
- Install the Rabby browser extension (available for Chromium-based browsers).
- Create a new wallet or import using a seed phrase / hardware wallet.
- Set up a password and back up your seed phrase in a secure offline place.
- Connect Rabby to dApps by approving only the permissions you understand.
Security & best practices
Rabby provides a number of built-in protections, but the safety of your funds depends mostly on your habits. Follow these best practices:
- Never share your seed phrase. Store it offline and encrypted.
- Enable hardware wallet usage for large bankrolls and critical transactions.
- Review contract approvals and revoke allowances you no longer need.
- Keep your extension and browser up to date; only install Rabby from the official store.
Troubleshooting common issues
If you run into problems, try these steps:
- Refresh the page and retry connecting the dApp.
- Restart your browser or reinstall the extension if UI components freeze.
- Check network settings — ensure you are on the correct chain (e.g., Ethereum Mainnet vs a testnet).
- For missing transactions, confirm the transaction status on a block explorer using the tx hash.
- If accounts aren’t showing, re-import using the seed phrase or connect a hardware wallet.
Frequently asked questions
Can I use Rabby with hardware wallets? — Yes. Rabby supports hardware wallet connections for additional security when signing transactions.
