What is the Coinbase Extension?

The Coinbase Extension is a browser extension that adds a lightweight wallet and interface for interacting with decentralized applications (dApps), signing transactions, and managing crypto assets. It is intended for users who want quick access to assets from their browser while maintaining control over transaction approvals.

Before you begin — quick safety checklist

Only install the extension from an official source. This guide does not provide external links.
Never enter or store your full recovery phrase in a browser or online document.
Use a strong, unique password for your browser profile and system account.
Enable two-factor authentication (2FA) for accounts that support it—but do not store 2FA codes in the browser extension itself.

Step-by-step — Install and set up

1. Install the extension

Find the Coinbase Extension in your browser’s official extension store or from Coinbase's verified resources. Confirm the publisher and reviews before installing. This guide avoids providing direct links.

2. Create or restore a wallet

On first run, choose whether to create a new wallet or restore an existing one using your recovery phrase. If creating a new wallet, write down the generated recovery phrase on paper and store it offline. If restoring, enter the recovery phrase only when you are certain you are using the correct, secure environment.

3. Choose a secure password (extension vault)

The extension will ask you to create a local password to encrypt the extension vault on your device. Choose a strong, unique password you can remember—do not reuse passwords from other services. This guide does not include any login/password links.

4. Backup and confirm

Follow the backup prompts to confirm your recovery phrase. Verify each word in order and keep the written backup in a secure location (e.g., safe or metal backup plate).

Using the extension — send, receive, and sign

Use the extension to view balances, request receive addresses, and sign outgoing transactions. The extension will display transaction details—amount, destination, and gas/fees—before requiring confirmation. Always verify these details carefully on-screen before approving.

Best practices for security

Verify addresses: always double-check the receiving address by comparing it to trusted records or device outputs when possible.
Keep recovery phrases offline: never type your recovery phrase into the browser or any website.
Limit extension permissions: grant the extension only the permissions it needs; avoid granting broad site access unless necessary.
Lock your extension when idle: close the extension or lock it when not actively using it to prevent unauthorized access.
Use hardware wallets for large balances: consider pairing the extension with a hardware wallet (if supported) for higher-value holdings so private keys are stored offline.
Use a dedicated browser profile: create a browser profile used only for crypto activity to reduce exposure.

Privacy considerations

Browser extensions can expose metadata like which sites you visit or dApp interactions. If privacy is a priority, use a separate browser profile and avoid exposing personal accounts while using crypto extensions.

Troubleshooting common issues

Extension not connecting: restart the browser, disable conflicting extensions, or try reinstalling the extension.
Missing funds: ensure you are viewing the correct network (e.g., Ethereum vs. other chains) and double-check the account address.
Restore failed: make sure the recovery phrase is entered correctly; check for extra spaces or incorrect word order.
Transaction pending: you may need to increase gas/fees or wait for network congestion to clear; check network explorers when necessary.

When to avoid using the extension

Avoid using the extension on public or shared computers, or on any device where you suspect malware. For large transfers or long-term storage, prefer hardware wallets or cold-storage solutions.
