Coinbase Extension® — Getting Started

Introduction

The Coinbase Wallet Browser Extension is a secure tool that allows users to manage cryptocurrency directly from their browser. It integrates with decentralized applications (dApps), supports multiple coins and tokens, and keeps private keys encrypted locally. Unlike Coinbase.com, the extension gives users full control over their funds without relying on a centralized exchange.

Key Features

Secure Private Key Storage: Keys remain encrypted on your device, not on a server.
Multi-Coin Support: Manage Ethereum, ERC-20 tokens, and other supported cryptocurrencies.
dApp Access: Connect to decentralized applications seamlessly from your browser.
Transaction Signing: Approve transactions securely without leaving your extension.
Backup & Recovery: Restore your wallet using a 12-word recovery phrase.

Installation Guide

Step 1: Install the Extension

Open your preferred browser (Chrome, Firefox, or Brave).
Go to the official Coinbase Wallet extension page: Coinbase Wallet.
Click “Add to Browser” or “Install”.
Confirm permissions and complete the installation.

Step 2: Set Up Your Wallet

Open the Coinbase Wallet extension icon in your browser.
Choose “Create New Wallet” or “Import Wallet”.
If creating a new wallet, write down your 12-word recovery phrase and store it securely offline.
If importing, enter your recovery phrase to restore your wallet.
Set a secure password for quick access to the extension.

Connecting to dApps

One of the main advantages of the Coinbase Wallet extension is its ability to interact with decentralized applications:

Visit a supported dApp website.
Click “Connect Wallet” and select Coinbase Wallet.
Approve the connection in your extension.
You can now use dApp features, including swaps, NFT marketplaces, and DeFi protocols.

Sending and Receiving Crypto

To send: Open your extension, select the asset, enter the recipient address, and approve the transaction.
To receive: Copy your wallet address from the extension and share it with the sender.
All transactions must be approved within the extension to ensure security.

Note: Always double-check recipient addresses and transaction details before confirming.

Security Best Practices

Never share your 12-word recovery phrase or password.
Install the extension only from official sources.
Keep your browser and extension updated.
Enable two-factor authentication on associated Coinbase accounts.
Consider using a dedicated browser profile for crypto activities.

Troubleshooting

Extension not loading: Clear browser cache or restart the browser.
Wallet not connecting to dApps: Ensure you approve connection in the extension popup.
Lost recovery phrase: You will need it to restore access if the wallet is removed or password is forgotten.

Conclusion

The Coinbase Wallet Browser Extension offers a secure, convenient way to manage cryptocurrency directly from your browser while interacting with decentralized applications. By following installation and security best practices, users can safely store, send, receive, and trade crypto without relying on centralized platforms, keeping full control over their assets.
