Coinbase Wallet Chrome Extension: Your Browser-Based Web3 Key

The Coinbase Wallet Chrome Extension is a non‑custodial plugin that turns your Chrome (or other Chromium‑based) browser into a secure gateway for Ethereum, EVM‑compatible chains, and decentralized applications (dApps). Unlike the custodial Coinbase.com platform, this extension keeps your private keys encrypted in your browser’s local storage—only you control them.

🛠️ Installation & Setup

1. Official Source Visit wallet.coinbase.com/extension and click “Add to Chrome” (works on Edge, Brave, Opera as well).
2. Create or Import Wallet
   • New Wallet: Follow the prompts to generate a fresh account and set a strong local password.
   • Import Wallet: Enter your existing 12‑ or 24‑word recovery phrase, then choose a new password.
3. Backup Reminder Securely write down your recovery phrase on paper. Coinbase never has access to it.

🔑 Key Features

• Multi‑Chain Support Built‑in networks include Ethereum, Polygon, BSC, Avalanche, Fantom, and more. You can also add custom RPC endpoints for less common chains.
• dApp Integration Injects a window.ethereum provider so sites like Uniswap, Aave, and OpenSea detect and connect seamlessly.
• Send & Receive Quick transfer interface with QR‑code support, address book, and transaction history.
• On‑Chain Swaps Swap tokens in‑extension via aggregated liquidity (powered by 0x), all signed locally.
• NFT Gallery View, send, and receive ERC‑721/ERC‑1155 collectibles directly from the extension.
• WalletConnect Connect to thousands of mobile‑only dApps by generating pairing QR codes.

🔒 Security Best Practices

• Never share your recovery phrase or enter it on any website.
• Use a unique, strong password to encrypt your extension data.
• Lock the extension when idle (click the profile icon → Lock).
• Verify dApp URLs before approving connections or transactions.

With the Coinbase Wallet Chrome Extension, you gain full custody of your keys alongside the convenience of a browser‑based wallet—empowering you to explore DeFi, NFTs, and the wider Web3 ecosystem without compromising security.
