Coinbase Extension — Manage Crypto in Your Browser

A lightweight, secure browser wallet that lets you store, send, and interact with decentralized apps without leaving your browser. Built for convenience and security, the Coinbase Extension simplifies daily crypto tasks while keeping you in control.

What is Coinbase Extension?

The Coinbase Extension is a browser-based wallet that connects your browser to the wider Web3 ecosystem. It lets you securely hold multiple cryptocurrencies, authorise transactions, and interact with dApps and smart contracts. Keys are encrypted locally — giving you control while providing an easy-to-use interface for everyday crypto needs.

Getting Started — Step-by-Step

Install the extension: Find the Coinbase Extension on the official Coinbase website or your browser’s extension store and add it to your browser.
Create or import a wallet: Open the extension and choose to create a new wallet or import an existing one using your recovery phrase.
Set a secure password: Create a strong password to encrypt your local wallet data.
Backup your recovery phrase: You’ll receive a recovery phrase — write it down and store it offline in a safe place.
Fund your wallet: Receive crypto from another address or transfer from your Coinbase account if supported.
Connect to dApps: When you visit a supported dApp, select "Connect Wallet" and approve the request inside the extension.

Trust & Security

Coinbase emphasises transparency and user protection. The extension stores encrypted keys locally and includes clear prompts to prevent accidental approvals.

Always verify extension sources and keep your recovery phrase private.
