Overview
Rabby Wallet Extension® in 100 words
Rabby Wallet Extension is a browser crypto wallet built for people who actually use DeFi. It runs in Chrome, Brave, Edge and Firefox and checks every transaction before you sign — showing what leaves your balance, what arrives, and where risk hides. Multi-chain by default, it surfaces your assets across Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism and more without hunting for networks by hand. Your keys stay on your device, guarded by a password and hardware wallet support. Install the extension, create or import a wallet, and see the full picture before every signature. Fewer surprises, every single time.

Features
What you get before every signature
Most wallets ask you to trust a button. This one shows its work first — balance changes, fees, approvals and warnings, all in the pop-up.
Risk warnings
Unlimited token approvals, unverified contracts and risky sites get flagged instead of slipping through.
Multi-chain in one wallet
Balances and activity across Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain and more, side by side.
Keys stay on your device
Non-custodial by design: your wallet is encrypted locally and unlocked with your own password.
Hardware wallet support
Pair a hardware wallet for the accounts that matter and keep day-to-day browsing in a separate one.
Switch from MetaMask
Import an existing wallet with its recovery phrase or a private key and keep the accounts you already use.
Setup
How to install the extension
Three steps, no account, nothing to configure in advance.
-
1
Add it to your browser
Open the official Rabby website and choose the build for Chrome, Brave, Edge or Firefox. Confirm the store listing name and publisher before you click “Add to browser”.
-
2
Create or import a wallet
Start a fresh wallet and write your recovery phrase down offline, or bring across an existing one. A hardware wallet can be connected here too.
-
3
Pin it and connect
Pin the icon to your toolbar, connect to the dApp you’re using, and read the preview every time it appears. That preview is the whole point.
Downloading from anywhere else?
Fake extensions copy the logo and the name perfectly. Get the extension from the official site or its official browser store listing — never from a search ad, a direct message or an emailed link.
Networks
One extension, many chains
Switch networks without leaving the wallet, and add any custom EVM network you need by hand.
- Ethereum
- Arbitrum
- Base
- Optimism
- Polygon
- BNB Chain
- Avalanche
- zkSync Era
- Linea
- Scroll
- Blast
- Gnosis Chain
- + custom EVM networks
Security
Three rules that protect your funds
A non-custodial wallet hands you full control, and that means full responsibility. These three habits prevent almost every story you read about lost crypto.
Read the FAQ- Never share your recovery phrase. No wallet, support agent, community moderator or website will ever need it. Anyone who asks for it is stealing from you.
- Read the preview, not the button. Check the amounts, the contract and the approval before you confirm. An unlimited approval is a permanent key to that token.
- Separate big balances. Keep a hardware wallet for savings and a small hot wallet for experimenting. Losing the small one should never hurt.
FAQ
Rabby Wallet Extension questions
The answers people look for before they install a browser wallet.
What is the Rabby Wallet Extension?
It’s a non-custodial crypto wallet that runs inside your browser as an extension. Your keys are encrypted on your own device, and every transaction is simulated before you approve it, so you see the balance changes, fees and approvals involved — rather than a bare “Confirm” button.
Which browsers support it?
Chromium-based browsers — Google Chrome, Brave, Microsoft Edge, Opera and Arc — plus Mozilla Firefox. Install the build that matches your browser and keep it updated through the browser itself.
Is the Rabby Wallet Extension free?
Installing and using the wallet costs nothing. The only charges you’ll see are blockchain network fees, which are paid to the network validators — not to the wallet.
Can I import my MetaMask wallet?
Yes. During setup you can create a new wallet or import an existing one with its recovery phrase or a private key, so the accounts and balances you already use appear straight away. Type your recovery phrase only inside the extension — never into a website, a chat or a form.
Where should I download it from?
Only from the official website or the official browser store listing. Search ads, direct messages and emailed links regularly point at convincing clones. Check the domain in the address bar and the publisher name in the store before installing.
Which networks are supported?
Ethereum and a long list of EVM networks including Arbitrum, Base, Optimism, Polygon, BNB Chain, Avalanche, zkSync Era, Linea, Scroll, Blast and Gnosis Chain. You can also add a custom EVM network with its own RPC details.
How do I stay safe using a browser wallet?
Write your recovery phrase on paper and keep it offline. Bookmark the sites you use instead of clicking search results. Review the transaction preview every time, revoke approvals you no longer need, and move larger balances to a hardware wallet.
