Made with GrigoraRabby Wallet Extension is a next-generation cryptocurrency wallet designed specifically for the decentralized finance (DeFi) ecosystem. Built by DeBank, a leading platform for tracking DeFi portfolios, Rabby has quickly become one of the most trusted non-custodial wallets among Web3 users. Unlike traditional browser wallets, Rabby Wallet Extension automatically detects the network you are interacting with and switches chains seamlessly, eliminating the frustration of failed transactions caused by wrong network settings.
The wallet is available as a browser extension for Chrome, Brave, Edge, and Firefox, as well as a mobile app for iOS and Android. With its clean interface, advanced security features, and multi-chain support, Rabby Wallet Extension has earned a reputation as the "smart wallet" for DeFi enthusiasts.
One of the most innovative features of Rabby Wallet Extension is its automatic network detection. When you visit a decentralized application (dApp), Rabby recognizes which blockchain it operates on and prompts you to switch — or switches automatically — before you sign a transaction. This prevents the common problem of sending tokens to the wrong network, which often results in lost funds.
Rabby Wallet Extension performs a security scan before every transaction. It simulates the outcome of the transaction and warns you about potential risks such as scam tokens, malicious contracts, or unexpected asset changes. This "pre-flight" check has saved countless users from falling victim to phishing attacks and rug pulls.
Rabby supports over 100 EVM-compatible networks, including Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, and many more. You can manage all your assets across these chains from a single interface without manually adding custom RPCs — though advanced users still have that option.
Because Rabby is built by DeBank, it integrates natively with DeBank's portfolio tracking tools. You can view your entire DeFi position — including lending, borrowing, staking, and liquidity providing — directly inside the wallet. This gives you a comprehensive view of your net worth across multiple protocols and chains.
Rabby Wallet Extension helps you save on gas fees by suggesting the most efficient transaction settings. It shows you real-time gas prices and allows you to adjust priority fees for faster or cheaper transactions depending on network congestion.
The wallet displays all your NFTs and tokens in an organized, searchable format. You can hide spam tokens, pin important assets, and view detailed information about each holding, including price charts and contract addresses.
Rabby Wallet Extension is a non-custodial wallet, meaning you alone control your private keys and recovery phrase. The extension stores encrypted keys locally on your device and never transmits them to any server. Additional security layers include:
Transaction simulation: Every transaction is pre-simulated to show exactly what will happen before you sign.
Scam detection: Rabby maintains a database of known scam contracts and warns you when you interact with them.
Phishing protection: The wallet blocks access to known phishing websites and flags suspicious domains.
Hardware wallet support: Rabby integrates with Ledger, Trezor, and other hardware wallets for cold storage security.
Multi-signature support: Advanced users can connect Safe (formerly Gnosis Safe) multisig wallets.
MetaMask has long been the dominant browser wallet, but Rabby Wallet Extension offers several advantages:
Automatic chain switching vs. MetaMask's manual network configuration
Pre-transaction risk scanning vs. MetaMask's limited warnings
Built-in DeFi portfolio tracking vs. MetaMask's basic asset view
Better gas estimation with real-time optimization
No hidden fees — Rabby does not charge a swap fee (as of 2024)
Many DeFi power users have migrated to Rabby while keeping MetaMask as a backup. The two can coexist in the same browser without conflict.
