The Coinbase Wallet Extension is a browser‑based cryptocurrency wallet designed to give users direct, self‑custody control over their digital assets and seamless access to the decentralized web (Web3). Unlike a custodial wallet tied to Coinbase.com where Coinbase controls private keys, the Wallet Extension stores your encrypted keys locally in your browser, ensuring you alone control your crypto funds and access.

🛠️ What It Is

The Coinbase Wallet Extension is a lightweight browser add‑on (primarily for Chrome, Brave, and Edge browsers) that lets you:

  • Manage crypto assets
  • Connect directly to decentralized apps (dApps)
  • Trade tokens using decentralized exchanges (DEXes)
  • Buy, sell, and view NFTs
    … all without leaving your browser window.

It acts as a bridge between your browser and Web3 applications, making it easy to interact with smart contracts, finance protocols (DeFi), blockchain gaming, and NFT marketplaces.

🔑 Key Features

✅ Self‑Custody Wallet

You have full control of your private keys and recovery phrase — Coinbase doesn’t hold your keys or access your funds. This ensures maximum ownership and privacy, but also means you are responsible for your recovery phrase.

🌐 dApp & Web3 Access

Once installed, the extension enables instant connection to decentralized apps. When a dApp asks to “Connect Wallet”, selecting Coinbase Wallet will let you interact directly with the service — no additional plugins or mobile confirmations needed.

📊 Multi‑Chain Support

Supports major EVM‑compatible networks such as:

  • Ethereum
  • Polygon
  • Avalanche
  • Arbitrum
  • Optimism
    … and others, so you can explore various ecosystems.

🪪 Token & NFT Management

View, receive, send, and manage:

  • ERC‑20 tokens
  • NFTs from supported chains
  • Transaction history across networks
    … all within the same interface.

🔐 Security & Encryption

  • Private keys are encrypted and stored locally
  • Optional connection to hardware wallets like Ledger or Trezor for enhanced security
  • Built‑in transaction previews to help prevent malicious activity.

🔄 Import Existing Wallets

If you previously used another wallet (e.g., MetaMask, Trust Wallet), you can import it into Coinbase Wallet using its 12‑word recovery phrase to manage assets from one place.

🚀 How to Install & Set Up

📥 1. Install Extension

Go to the Chrome Web Store (or supported browser store) and add the Coinbase Wallet Extension to your browser toolbar.
👉 Use official links — don’t trust random search results to avoid scams.

🆕 2. Create a New Wallet

  • Choose Create new wallet
  • Securely back up your 12‑word recovery phrase
  • Confirm the phrase
  • Set a strong wallet password
    This lets you begin using your wallet immediately.

🔁 3. Import Existing Wallet

Instead of creating a new wallet, you can import one using a recovery phrase. This is useful if you already use wallets like MetaMask or Trust Wallet.

🔐 4. Secure Your Wallet

Always store your recovery phrase offline (e.g., on paper or secured note) and never share it.
