Coinbase Wallet Browser Extension

Presentation / Getting Started Guide

1. Introduction

The Coinbase Wallet browser extension is a powerful tool that brings self‑custody wallet functionality directly into your web browser. Unlike centralized exchange wallets, this extension empowers you to manage your crypto assets, interact with decentralized applications (dApps), and control your private keys locally — all without leaving your browser window.

In this presentation, we’ll explore what the extension is, how to get started, its main features, security practices, and practical tips for daily use. Whether you’re just beginning with crypto or already familiar with decentralized finance (DeFi), this guide will help you confidently navigate the Coinbase Wallet extension.

2. What Is Coinbase Wallet Extension?

The Coinbase Wallet extension is a browser‑based cryptocurrency wallet that lets you:

  • Store and manage crypto assets
  • Interact with Web3 applications (dApps) such as DeFi platforms, NFT marketplaces, DAO governance, and more
  • Sign transactions directly in your browser
  • Keep full control over your private keys and recovery phrase

Unlike custodial wallets on exchanges (where an institution holds your keys), this extension makes you the sole owner of your private keys, keeping them encrypted and locally stored.

This self‑custody model ensures that your crypto is yours alone — with responsibility for secure backups and safe usage.

3. Why Use the Coinbase Wallet Extension?

A. Full Control of Your Assets

With the Coinbase Wallet extension, private keys are stored locally on your device — not on Coinbase servers — giving you direct control over your funds and security.

B. Seamless Web3 Interaction

The extension enables one‑click connection to thousands of decentralized applications (dApps) — including DeFi, NFT platforms, and more — from within your browser.

C. Multi‑Chain & Multi‑Asset Support

Manage a wide range of assets, including Ethereum, ERC‑20 tokens, and other blockchain networks supported by the wallet.

D. Built‑In Features

The wallet includes built‑in controls for sending/receiving crypto, swapping tokens, and viewing NFT collections — all without switching interfaces.

E. Hardware Wallet Integration (Optional)

For additional security, you can connect hardware wallets like Ledger to the extension for offline key storage and transaction signing.

4. Supported Browsers and Platforms

The Coinbase Wallet extension is compatible with Chromium‑based browsers, including:

  • Google Chrome
  • Brave
  • Microsoft Edge
  • Other Chromium variants
    (Firefox support is limited and may expose users to unofficial versions or scams, so always verify you are installing the official extension.)

5. Installation & Setup (Step by Step)

  1. Visit the official Coinbase Wallet website or your browser’s extension store.
  2. Search for “Coinbase Wallet Extension”.

  5. Confirm backup and proceed. Coinbase
Note: Coinbase cannot recover your recovery phrase, so write it down offline and keep it secure. Coinbase

C. Import an Existing Wallet

If you already have a self‑custody wallet (e.g., MetaMask, another Coinbase Wallet), you can import it by entering your recovery phrase during setup. Coinbase

6. Daily Use and Features

Once set up, you can:

A. Manage Crypto

Send, receive, and view your assets conveniently from the extension interface.

B. Swap Tokens

Many users can perform on‑chain token swaps directly within the wallet, aggregating liquidity across networks.

C. Connect to dApps

Visit Web3 sites and click Connect Wallet to interact with decentralized finance platforms, NFT marketplaces, etc. All actions require your approval.

D. NFT Management

View and manage NFTs directly in the extension, including sending and receiving compatible tokens.

E. Network Switching

7. Security Considerations

The security of your crypto assets depends on safe practices:

A. Local Key Encryption

The extension stores keys locally in encrypted form. Coinbase cannot access your private keys unless you export them.

B. Recovery Phrase Responsibility

Your recovery phrase is the critical safety net. Losing it means losing access to your wallet forever. Always keep multiple backups in secure off‑line locations. Coinbase

C. Beware of Fake Extensions

Fraudulent extensions (especially on less popular browsers) can steal your keys. Only install from trusted sources.

D. Approve Only Trusted Permissions

When connecting to dApps, review permission requests carefully. Only approve actions you trust.

8. Advanced Tips

  • Enable hardware wallet integration for large balances.
  • Sync the extension with your Coinbase Wallet mobile app for biometric security and cross‑device access.
