Coinbase® Extension® | Getting Started: Wallet Extension

The Coinbase Wallet Extension is a browser-based, self-custody cryptocurrency wallet developed by Coinbase, one of the world’s most trusted and regulated crypto platforms. Unlike the centralized Coinbase exchange, Coinbase Wallet gives users full control over their crypto and private keys, making it an ideal tool for accessing decentralized applications (dApps), managing digital assets, and interacting with Web3 securely and conveniently.

🌐 What is the Coinbase Wallet Extension?

The Coinbase Wallet Extension is available for Google Chrome and other Chromium-based browsers like Brave and Edge. It acts as a non-custodial Web3 wallet that lets users:

  • Store cryptocurrencies and NFTs
  • Connect to decentralized apps (DeFi, gaming, NFTs)
  • Swap tokens directly
  • Interact with Ethereum and other supported networks

Because it's a browser extension, the Coinbase Wallet enables instant, secure access to dApps without needing to leave the browser or use a mobile app. It's designed for both beginners and experienced users exploring the decentralized internet.

🛠️ Key Features

🔐 Self-Custody & Security

  • Your wallet, your keys. The extension gives you complete control over your private keys.
  • During setup, you'll receive a 12-word recovery phrase—the only way to restore your wallet. This phrase must be kept offline and private.
  • Coinbase does not store your recovery phrase, making your wallet truly yours.

🔗 Seamless dApp Access

  • Connect instantly to dApps like Uniswap, Aave, Compound, OpenSea, and more.
  • Sign and confirm transactions directly in the extension window.
  • No need to copy/paste addresses or use third-party bridges.

💱 Token Swaps

  • Built-in swap functionality lets you exchange tokens across supported networks without leaving your browser.
  • Powered by decentralized liquidity sources for better pricing and lower slippage.

🌉 Multi-Chain Support

  • Native support for Ethereum (ETH) and EVM-compatible chains such as:
  • Polygon (MATIC)
  • Avalanche
  • BNB Smart Chain (BSC)
  • Arbitrum, Optimism, and more

Users can manually add custom networks using RPC settings, similar to MetaMask.

🖼️ NFT Support

  • View and manage ERC-721 and ERC-1155 NFTs directly in your wallet.
  • Easily connect to NFT marketplaces and games from your browser.

🔗 Mobile Sync Option

  • If you already use the Coinbase Wallet mobile app, you can sync it with the extension using a QR code.
  • This makes it easy to manage the same wallet across devices.
