What Rabby is, how it protects you from scams, and actionable steps to use it safely across Ethereum-compatible chains.
Rabby is an open-source browser extension wallet built for DeFi users and EVM-compatible chains. It focuses on transaction previews, risk scanning, and UX improvements to reduce common phishing and approval mistakes when interacting with dApps.
Rabby also provides desktop/mobile projects and documentation, and it integrates with hardware devices and WalletConnect where appropriate.
Rabby targets the exact moments where users make costly mistakes — signing unsafe approvals or falling for phishing dApps — by surfacing clearer information before you hit "confirm."
see estimated balance changes and contract calls before signing.
automatic warnings for suspicious tokens, contracts, or origin mismatches.
smooth switching for chains like Ethereum, Polygon, BNB Chain, and others.
works with Ledger and other secure-key solutions for cold storage workflows.
Browser extensions are convenient but can be impersonated. Security research shows malicious add-ons often mimic popular wallets (including Rabby) to steal keys. Always download Rabby from the official site or verified stores and check the extension ID.
Visit rabby.io or the verified Chrome/Brave extension page and add the extension. Confirm publisher and extension ID to avoid fakes.
You can create a new non-custodial wallet (seed phrase stored locally) or import an existing seed. Follow best practices for storing the seed offline.
Turn on Rabby's anti-phishing/risk scan features and any available safeties (origin checks, restrict approvals, simulation). These reduce the surface for accidental approvals.
Before interacting with large positions or unfamiliar contracts, send a small test amount and observe the transaction preview and result.
Rabby aims to be a safer DeFi gateway by prioritizing contextual transaction info (what will change in your balance, which contracts will be called) rather than presenting raw low-level data that beginners misinterpret. This focus reduces risky approvals and improves clarity.
| Feature | Rabby | Typical wallet |
|---|---|---|
| Transaction preview | Detailed simulation & balance-change view | Raw calldata + gas estimate |
| Risk scanning | Built-in scam/token/contract flags | Often third-party or none |
| Hardware support | Yes — Ledger & others | Varies |
| Mobile availability | Mobile app & desktop projects exist (official mobile in stores) | Often mobile-only or extension-only |
Rabby significantly reduces risk by surfacing contract details and flagging suspicious origins, but it cannot prevent user-authorized transfers (if you explicitly approve a malicious contract) or defeats of physical key security (seed phrase leaks). Security is layered: Rabby helps with the UX/transaction layer, but seed hygiene, hardware keys, and cautious dApp behavior remain essential.
Rabby Wallet brings thoughtful UX and safety tooling to the DeFi experience — a practical choice for users who want clearer transaction context and extra safeguards when interacting with smart contracts. Combine Rabby with hardware keys, seed-phrase discipline, and conservative approval habits for a much stronger security posture.
