Overview
What the Rabby Wallet extension actually is
An extension wallet is a small add-on you install in a desktop browser. It adds a wallet panel to your toolbar, and it talks to web apps that support crypto wallets — so you can connect, sign and send without a separate app running on your computer.
Rabby Wallet is an EVM-first wallet developed by the team behind DeBank, a long-standing portfolio and data tool for Ethereum users. Instead of treating each network as a separate wallet you must switch between, it is designed around the idea that a site tells the wallet which network it wants, and the wallet handles the rest.
The part people most often mention is the pre-transaction view: before you confirm, you get a preview of what the transaction is expected to do and the risks the wallet can detect. A companion approvals dashboard lets you review and revoke token permissions you granted in the past — useful housekeeping if you have been using crypto sites for a while.
This page describes the extension in general terms for orientation only. Features, supported networks and interface details change over time — the official site and its documentation are the authoritative source.
Features
The features users talk about most
A quick orientation to what sets this kind of wallet apart — not a full specification.
-
Multi-chain by default
Built around EVM networks, so the wallet can meet a site on the network it asks for instead of making you switch manually first.
-
Transaction preview
Before you confirm, you see a simulation of the expected outcome and warnings for the risks the wallet can detect.
-
Approvals dashboard
See the token permissions you have granted across sites and revoke the ones you no longer need from one place.
-
Gas and speed control
Adjust how much you pay for a transaction, speed it up or cancel it when a network is congested.
-
Hardware wallet support
Commonly paired with a hardware device, so signing keys stay on the device instead of in the browser.
-
Swaps and bridges in-wallet
Swap or move assets between supported networks without leaving the wallet for a third-party site.
Feature lists are summarised for orientation. For the current, exact list, check the official documentation at rabby.io.
Setup
Safe-install checklist
Six steps that take a couple of minutes and remove almost all of the risk from installing a wallet extension.
-
Start at the official site
Type rabby.io into the address bar yourself. Never install from a search ad, a sponsored result, a QR code or a link someone sent you.
-
Follow the download link to the browser store
The official site links to the extension's listing in the browser's own store. Installing from the store keeps you under the browser's extension review and update process.
-
Check the publisher and the user count
On the listing, confirm the developer name matches what the official site says, and read the recent reviews. Clones almost always have a mismatched publisher and a tiny, brand-new user base.
-
Bookmark the real site before you go further
Bookmark the page you are on. From now on, use the bookmark every time — it is the simplest defence against a convincing look-alike address.
-
Write your recovery phrase on paper
No screenshots, no photos, no cloud notes, no password manager entry, no email to yourself. Anyone who has those words owns the wallet.
-
Pin the extension and test with a small amount
Pin it so you always know which wallet you are looking at, then send a small test transaction before moving anything significant.
Safety
The four things that actually get wallets drained
Crypto theft is rarely clever code-breaking. It is a convincing page and a person in a hurry.
The one rule that never changes
Your recovery phrase is your wallet. No wallet, exchange, support agent, or giveaway will ever legitimately ask you to type it into a website, a chat, a form, or a "wallet validation" page. If a page asks for those words, it is stealing from you — close it.
Red flags
- Anyone asking for your recovery phrase or private key.
- A "wallet" site on an address that is not the official domain.
- Search ads and sponsored results for the wallet's name.
- "Support" agents who message you first on social media or Discord.
- Extensions with a strange publisher name or almost no history.
- Urgency: "verify now or your funds will be frozen".
Habits that protect you
- Reach the wallet only through a bookmark you made yourself.
- Check the domain letter by letter before typing anything.
- Keep the recovery phrase offline, on paper, somewhere physically safe.
- Read the transaction preview, and don't sign what you don't understand.
- Revoke approvals you no longer use.
- Use a hardware wallet for meaningful amounts.
FAQ
Questions people ask first
Is this the official Rabby Wallet website?
No. This is an independent informational page written to explain the extension and how to install it without getting scammed. It is not affiliated with, endorsed by, or operated by Rabby Wallet or DeBank. The official site for the wallet is rabby.io.
Is the Rabby Wallet extension free?
The wallet itself is free to install and use — there is no subscription. What you do pay are network fees (gas) whenever you send a transaction or interact with a blockchain app. Always confirm current pricing and terms on the official site.
Where should I get it from?
From the official site, following its own download link through to the browser's extension store listing. Installing straight from the browser store is fine too — as long as you check the publisher name against what the official site says before you click "Add".
Which browsers and devices does it support?
It is a browser extension, so it runs in desktop browsers that support extensions. Compatibility lists and any mobile options change over time, so check the official site for what is currently supported rather than relying on a page like this one.
Does the wallet hold my crypto?
No. This type of wallet is self-custody: your assets live on the blockchain and are controlled by keys generated on and kept on your device. That is exactly why the recovery phrase matters so much — there is no company that can reset it or recover your funds for you.
Can I import a wallet I already use?
Extension wallets generally let you bring an existing wallet in by entering its recovery phrase, or create a fresh one. Whichever route you take, do it in a private place with no screen sharing, and consider a brand-new wallet if you are unsure. Confirm the exact steps in the official documentation.
Does it work with non-EVM chains?
The extension is aimed at Ethereum and EVM-compatible networks. For the current list of supported chains, and any support beyond that, the official site is the only source worth trusting.
Copywriting
Rabby Wallet Extension® in 100 words
A ready-to-use overview you can drop into a briefing, a blog post, or an app listing.
Rabby Wallet Extension® is a browser-based crypto wallet built for Ethereum and every EVM-compatible network. Instead of juggling separate wallets for separate chains, you connect once and Rabby detects which network a site is asking for. Before you sign anything, it previews the transaction, shows what leaves your wallet, and flags risky approvals — so you can decide with facts, not guesswork. A single dashboard lets you review and revoke permissions in seconds. Keys stay on your device; nothing is ever shared with any server. Free to install, designed to make self-custody calmer for everyday users and experienced traders alike.
