This official-style guide helps you install and set up the Coinbase Extension, create or import your wallet, manage digital assets, and connect safely to Web3 applications — all with essential security practices.
The Coinbase Extension is a browser-based crypto wallet that lets you manage tokens, NFTs, and DeFi assets directly in your browser. It integrates seamlessly with your Coinbase account and the Coinbase Wallet mobile app to enable fast transactions, decentralized trading, and app connectivity across Ethereum and supported networks.
Download the Coinbase Extension only from the official Chrome Web Store or supported browser marketplaces. Avoid third-party websites or unofficial links. After installation, click the Coinbase icon in your browser’s toolbar to open the extension interface.
New users can choose “Create new wallet” and follow on-screen instructions to generate a recovery phrase (also known as a seed phrase). If you already have a Coinbase Wallet, select “Import existing wallet” and input your 12-word recovery phrase securely. Never share your recovery phrase with anyone — it grants full access to your assets.
Set a complex password that is unique to your Coinbase Extension. Use a mix of characters, numbers, and symbols. Store it in a trusted password manager. This password only unlocks your wallet locally on your computer and does not recover it if lost — your recovery phrase remains the ultimate backup.
Write down your recovery phrase on paper or store it on a metal plate. Keep it in a safe, offline location away from digital devices. Never upload it to cloud storage or email. This is your only method of restoring wallet access if your device is lost, damaged, or reset.
Once installed, you can use the Coinbase Extension to connect to supported dApps such as Uniswap, OpenSea, or Aave. When prompted, select “Connect Wallet” and choose Coinbase Wallet. Review permissions before granting access to ensure the dApp is legitimate.
Access your token balances, NFTs, and transaction history directly from the extension. You can send or receive crypto by clicking “Send” or “Receive” within the wallet interface. Always double-check wallet addresses and network selections before confirming transactions.
Use the Coinbase Extension on personal, secure devices only. Keep your browser, operating system, and wallet updated. Consider pairing your Coinbase Wallet with a hardware wallet like Ledger for extra protection of your private keys.
If you can’t access your Coinbase Extension, ensure your browser is up to date and disable conflicting extensions. If your wallet won’t unlock, try re-entering your password or reimporting with your recovery phrase. For persistent issues, consult Coinbase’s official Help Center for verified support articles.
