Rabby Wallet

Open source EVM wallet that scans transactions for risk and previews balance changes before you sign.

Last updated November 2026

About Rabby Wallet

Rabby is a free, open source wallet from the DeBank team, built for people who use decentralised apps on Ethereum and other EVM chains. Its central idea is to show you what a transaction will do before you sign it. The store listing describes pre-transaction risk scanning and a preview of the balance change, and the wallet is designed for a smooth multi-chain experience.

The code is on GitHub under an MIT licence, and Least Authority audited the extension, with a final report in December 2024 and a second review in September 2025. It handles EVM networks only, so Solana and Bitcoin users need another wallet. It is in the Chrome Web Store, so it also installs in Chromium browsers such as Edge and Brave, but there is no Firefox or Safari version.

One past incident belongs here. In October 2022, less than a month after Rabby Swap launched, an attacker exploited a flaw in the Rabby Swap smart contract to move tokens users had approved, and Rabby told users to revoke their approvals. Reports differed on the amount lost. Pre-signing checks reduce risk but do not remove it, so read what you approve. For most DeFi users on EVM chains, this is our first choice.
