Coinbase Wallet Extension

What is the Coinbase Wallet Extension?

The Coinbase Wallet Extension is a non-custodial crypto wallet that lives directly in your web browser. Designed for the decentralized web (Web3), it allows you to store your digital assets, interact with decentralized apps (dApps), manage NFTs, and more—all without leaving your browser.

It’s part of the Coinbase Wallet ecosystem, which also includes a mobile app. With the browser extension, users get an easy, secure, and fast way to access Ethereum-based apps, send tokens, and manage their digital identity across the blockchain.

Key Features

• Self-Custody: You own your private keys. Coinbase never has access to your funds.
• Connect to dApps: Instantly link with popular dApps like Uniswap, OpenSea, Compound, and more.
• Secure Storage: Store ETH, ERC-20 tokens, and NFTs safely in your browser wallet.
• Cross-Device Sync: Connect your mobile Coinbase Wallet to the extension for seamless experience.
• Private and Encrypted: Your seed phrase is encrypted and stored locally in your browser.
• Gas Fee Customization: Set gas prices manually or use default settings for fast confirmations.

How to Install the Coinbase Wallet Extension

1. Visit the official site: coinbase.com/wallet
2. Click “Download Extension” and choose your browser (Chrome, Brave, Edge).
3. Click “Add to Chrome” or “Install” from the browser’s extension store.
4. Open the extension and either create a new wallet or import using a recovery phrase.
5. Back up your 12-word recovery phrase securely (offline only).
6. Set a strong password and start using your wallet!

Security Tips

With great control comes great responsibility. Here are some security best practices:

• Never share your recovery phrase with anyone—even Coinbase support.
• Backup your seed phrase on paper or a hardware backup device.
• Use a strong and unique password for the extension.
• Enable biometric security (if available on mobile wallet sync).
• Always double-check the URL of dApps you connect with to avoid phishing.

Troubleshooting Login and Sync Issues

• Extension not opening: Make sure it's enabled in your browser's extension settings.
• Forgot password: You’ll need to reset the extension and restore it using your recovery phrase.
• Mobile not syncing: Ensure both devices are on the same Wi-Fi and the latest app version is installed.
• Network not showing: Manually add the network using RPC settings.
