🧠 1. What Is the Rabby Extension?

Rabby Extension is the browser extension version of the Rabby Wallet — a non‑custodial Web3 wallet built primarily for Ethereum and EVM‑compatible chains such as Polygon, Arbitrum, BNB Chain, Optimism, and many more. It allows users to interact directly with decentralized applications (like Uniswap, OpenSea, Aave) without exposing private keys to third parties. (Google Sites)

Being non‑custodial means you always control your private keys and seed phrase, and Rabby never stores your wallet or funds. (Google Sites)

👉 You can find the official project site and download sources on the official Rabby Wallet site. (support.rabby.io)

🔍 2. Core Features & Benefits

Rabby Extension has quickly become popular because it blends professional‑grade functionality with intuitive usability. Here are the standout features:

✔️ Multi‑Chain Support (Automatic)

When connecting to a decentralized app, Rabby automatically detects the correct network and switches to it for you. No manual RPC setup, no network confusion — this is excellent for seamless DeFi and NFT interactions. (rabbys.at)

✔️ Transaction Simulation & Preview

Before you sign a transaction, Rabby runs a pre‑transaction simulation showing exactly what will happen — including balance changes, fees, and any unusual contract behavior. This reduces blind signing risks dramatically. (rabbys.at)

✔️ Approval Management

Rabby helps you track and revoke token spending approvals granted to dApps, which is critical for limiting exposure to malicious contracts or unauthorized asset spending. (rabbys.at)

✔️ Hardware Wallet Support

For added security, Rabby can connect to hardware wallets like Ledger, Trezor, Keystone, etc., letting you securely sign transactions with your private keys offline. (rabbys.at)

✔️ Portfolio & NFT Management

View all tokens, NFT assets, and portfolio metrics across supported chains in one unified dashboard — fast, clean, and informative. (rabbys.at)

✔️ MetaMask Compatibility

Rabby supports importing existing MetaMask seed phrases and wallets, so migration is straightforward for existing users. (rabbyewalletextension.typedream.app)

🛠️ 3. How to Install & Set Up Rabby Extension

Here’s an official step‑by‑step breakdown from Rabby’s own documentation:

1. Visit the official Rabby site: https://rabby.io/ — this is the recommended source to avoid fake downloads. (support.rabby.io)
2. Click Download and choose the browser extension (Chrome, Brave, Edge; Firefox support tends to be unofficial, so be cautious). (support.rabby.io)
3. Install via the browser’s official extension store.
4. After installation, open Rabby and create a new wallet or import an existing seed phrase.
5. Store your seed phrase securely offline — this is your only backup. (support.rabby.io)

🔐 4. Security Best Practices with Rabby

While Rabby enhances security compared to many alternatives, users should still follow strong safety practices:

🔒 Always Download From Official Sources

Only use the official domain rabby.io or your browser’s extension marketplace from verified / publisher sources. Downloading from third‑party sites can expose you to scam extensions. (rabbys.at)

🛑 Watch Out for Fake Extensions

There have been reports of fake wallet extensions mimicking Rabby that can steal seed phrases and drain wallets. This risk is especially prevalent on lesser‑known extension marketplaces. (TechRadar)

📜 Backup Your Seed Phrase Offline

Write your seed phrase on a secure medium — never in cloud notes or screenshots. This is critical if you ever lose access to your device. (support.rabby.io)

🧠 Enable Hardware Wallet Integration

Pairing Rabby with a hardware wallet keeps your keys offline even while using Rabby’s interface. This is one of the strongest safeguards against hacks. (rabbys.at)

🌐 5. Using Rabby with dApps

Once installed, connecting Rabby Extension to a decentralized application is straightforward:

1. Open any Web3 site like a DEX (e.g., Uniswap), NFT marketplace (e.g., OpenSea), or DeFi platform.
2. Click Connect Wallet.
3. Choose Rabby Wallet in the popup.
4. Rabby will auto‑switch the right blockchain and request connection confirmation. (support.rabby.io)

If a dApp doesn’t list Rabby explicitly, you can often select MetaMask and let Rabby emulate MetaMask for connection if needed. (support.rabby.io)

⚔️ 6. Rabby vs. Other Wallets (e.g., MetaMask)

Rabby is specifically tailored for DeFi and multi‑chain interactions, while MetaMask is a general‑purpose wallet. Many advanced users use Rabby alongside MetaMask for its security and utility advantages. (rabbys.at)
