Frequently Asked Questions
Is Coinbase Extension® free to use?
Yes, Coinbase Extension® is completely free to download and use. There are no subscription fees or hidden charges. Standard blockchain network fees (gas fees) apply for transactions, and the built-in swap feature may include small exchange fees that are clearly displayed before confirmation.
How is the extension different from Coinbase.com?
Coinbase Extension® is a self-custody wallet where you control your private keys, while Coinbase.com is a custodial exchange service. The extension focuses on Web3 interactions, dApp connectivity, and decentralized finance, whereas the main website is for trading and investment services with Coinbase holding your assets.
Can I use the extension without the mobile app?
Yes, the Coinbase Extension® functions independently and doesn't require the mobile app. However, using both provides enhanced features like cross-device synchronization, mobile backup options, and the ability to approve transactions from your phone for added security.
Is my recovery phrase stored by Coinbase?
No, Coinbase never has access to your recovery phrase or private keys. All sensitive information is encrypted and stored locally on your device. This ensures you maintain complete control and ownership of your assets while using the extension.
What happens if I uninstall the extension?
If you uninstall the extension without backing up your recovery phrase, you will permanently lose access to your funds. Always ensure you have securely stored your 12-word recovery phrase before uninstalling. With the recovery phrase, you can restore your wallet on any compatible device or extension installation.
Which blockchain networks are supported?
Coinbase Extension® supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche, and other EVM-compatible networks. The extension automatically detects supported networks when connecting to dApps and allows you to easily switch between networks for different applications and services.
