See the risk before you sign
Transaction preview
Rabby simulates every signature and shows your balance changes, the contract’s reputation and any known scam addresses before you approve anything.
Automatic chain switching
Open a dApp and the wallet moves to the network that dApp uses, so you never sign on the wrong chain by accident.
Approval manager
Review old token permissions in one built-in list and revoke the ones you no longer trust, whenever you like.
From Install to First Safe Sign
Four quick steps take you from a fresh browser to a signed transaction, and your keys never leave your device.
01.
Install the extension
Add Rabby Wallet to Chrome or Firefox from the official store in under a minute, then pin it to your toolbar for quick access.
02.
Bring your wallet
Import a seed phrase, connect a hardware wallet or add a watch-only address. Your keys stay local, encrypted on your own device.
03.
Connect to any dApp
Open a dApp and connect. Rabby picks the right chain for you, so there is no manual network switching or guesswork.
04.
Review, then sign
See a simulated outcome of the transaction, including balance changes and risks, before you approve and sign with confidence.
Rabby versus the usual wallet
Same job, very different experience. Here is what changes the moment you sign a transaction, switch a network or review who can spend your tokens.
What you check
A typical single-chain wallet
Rabby Wallet
Signing
You approve a raw hex payload and have to trust it blindly.
You read a plain-language simulation of exactly what will happen first.
Networks
You switch networks by hand and a wrong chain means a failed transaction.
The wallet switches to the right chain automatically for each dapp.
Approvals
Token approvals stay hidden, so old permissions linger for years.
A revoke dashboard lists every approval and lets you cancel it.
Code
The source is often partly closed and hard to audit.
All code is published openly under the MIT licence.
Trusted by careful users
“Rabby flagged a drainer contract before I signed. The warning was plain, specific and saved my funds.”
Mira Osei, DeFi analyst
“I revoked forty stale approvals in one afternoon. Every old permission sat in one tidy list.”
Tomas Haldi, NFT collector
“The code is open source, so I audited it myself. Nothing hidden, and that is why I use it daily.”
Yuki Mori, protocol engineer

Questions before you install
The things careful users ask us first, answered plainly.
Is Rabby open source and audited?
Yes. Rabby’s code is published on GitHub under an open licence, so anyone can read it, build it and compare it with the release you install. Independent security firms have reviewed the wallet, and the findings are public. An audit lowers risk but never removes it, so keep your own habits sharp.
Where are my private keys stored?
Your keys are generated and encrypted on your own device and never leave it. Rabby has no account system and no server that holds your secrets, so nobody at the company can see or recover them. That also means your backup phrase is the only way back in: write it down offline.
Which chains and hardware wallets work with it?
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 open. Ledger, Trezor and Keystone can be connected, so signing stays on the device in your hand.
Can I import my existing MetaMask seed phrase?
Yes. Choose import, enter your twelve or twenty-four words, and your accounts appear with the same addresses and balances. Do this only on the official extension, and never type your phrase into a website. Your MetaMask can stay installed, so you can test Rabby first.
What does the transaction simulation check, and can it be wrong?
Before you sign, Rabby runs the transaction and shows which tokens leave and arrive, which approvals you grant, and whether the contract or address was flagged as risky. It can be wrong: new scams, unusual contracts and changing network conditions may slip past. Treat it as a second pair of eyes, not a guarantee.
