How to install and set up the Coinbase wallet extension

1. Install the extension: Visit the official browser store, search for the Coinbase wallet extension, and add it to your Chromium-based browser (e.g., Chrome, Brave, Edge, Opera). Always double-check the publisher and reviews.
2. Create or import a wallet: Choose “Create new wallet” for a fresh start, or “Import wallet” with your 12-word or 24-word recovery phrase. Store that phrase offline and never share it.
3. Set a strong password: This encrypts your wallet locally. Use a unique, long password and consider a password manager.
4. Choose your networks: Select Ethereum by default and add popular L2s like Base, Polygon, Arbitrum, and Optimism. You can also add custom RPC networks when needed.
5. Fund your wallet: Receive crypto from another wallet, transfer from an exchange, or use an integrated onramp where available.

Frequently Asked Questions about Coinbase wallet extension

Is the Coinbase wallet extension the same as the Coinbase exchange?

No. The Coinbase wallet extension is a self-custody wallet where you control your private keys. The Coinbase exchange is a centralized platform account. You can optionally connect them for easier funding, but they are separate products with different custody models.

Which browsers support the Coinbase wallet extension?

The Coinbase wallet extension is available for Chromium-based browsers such as Google Chrome, Brave, Microsoft Edge, and Opera. Always install from the official store listing and verify the publisher. Check the latest documentation for any newly supported browsers.

What networks can I use with the Coinbase wallet extension?

It supports major EVM networks including Ethereum, Base, Polygon, Arbitrum, Optimism, BNB Chain, and Avalanche C-Chain. You can also add custom RPC networks. Make sure you select the correct network before sending assets or interacting with dApps.

Are there fees to use the wallet?

The Coinbase wallet extension is free to install. Network transactions (like sends, swaps, or mints) incur blockchain gas fees paid to miners or validators—not to Coinbase. Some in-wallet services may include a clearly displayed fee.

Yes. You can import the same recovery phrase into the Coinbase wallet extension and the mobile app to access the same on-chain accounts across devices. Always verify you’re using official apps and extensions before importing sensitive information.

Is it safe to connect the Coinbase wallet extension to any dApp?

Connect only to trusted dApps. Review permissions, read what you’re signing, and revoke approvals you no longer need. Bookmark official URLs and be cautious of unsolicited links, pop-ups, or urgent messages requesting your recovery phrase.
