Rabby Wallet Extension
Connect to any dApp
Link your wallet to decentralized apps across many chains without switching networks by hand. Rabby changes to the right chain for each site, so you spend less time on setup and more time using the app.
Simulate before signing
Every transaction is previewed before you confirm it. You see exactly which balances will rise or fall, so there are no surprises after you sign and far fewer costly mistakes along the way.
Scan for risk
Addresses and contracts are checked against known threats the moment you interact with them. Warnings appear before you approve anything, helping you avoid scams, phishing traps and malicious approvals.
See every chain
One portfolio view brings your tokens and balances from all supported networks together. You can track your total holdings at a glance without opening a separate explorer for each chain.
What Rabby does

How it works
A typical wallet
• Shows raw hex data that no one can read before approving.
• Displays an unknown contract address with no context.
• Leaves you guessing which chain the request will use.
• Treats every contract the same, verified or not.
Rabby Wallet Extension
• Shows simulated balance changes before you sign.
• Names the chain the transaction will actually use.
• Flags unverified contracts with a clear risk warning.
• Every approval ends as an informed signature.
Sign with your eyes open
Dana Whitlock
"I caught a malicious approval before signing it. The clear preview showed exactly what I was giving away, and I simply rejected it that day."
Marcus Feld
"Eight chains used to mean eight tabs and constant network switching. Now all my balances and activity sit together in one clean view."
Priya Raman
"I moved over from my old legacy wallet in a few minutes. Import was easy, my tokens appeared, and nothing felt unfamiliar or risky."

Pricing
Which browsers does Rabby support?
Rabby runs as an extension on Chrome and on other Chromium browsers such as Brave and Edge. Install it from the official store page, pin it to your toolbar, and it is ready within a minute.
Does my seed phrase leave my device?
No. Your seed phrase and private keys are encrypted and stored locally in your browser. They are never sent to a server, and nobody on the team can see or recover them for you.
Which chains are covered?
Rabby supports Ethereum and a long list of EVM networks, including Arbitrum, Optimism, Base, Polygon and BNB Chain. It switches networks automatically to match the app you are using.
How does transaction simulation work?
Before you sign, Rabby runs the transaction in a simulation and shows the exact balance changes. Risky approvals and suspicious contracts are flagged, so you know what will happen before you confirm.
Can I use a hardware wallet?
Yes. You can connect Ledger, Trezor and other popular hardware wallets, then sign with them from the extension. Your keys stay on the device while Rabby handles the interface and checks.
How do I import another wallet?
Choose import in the extension, then enter your seed phrase or private key from MetaMask or another wallet. Your addresses appear immediately, and you can keep several wallets side by side.
