Coinbase Extension — Starting Up Your Device | Coinbase®

The Coinbase Extension provides a convenient way to access a crypto wallet directly from a compatible web browser. It can be used to interact with decentralized applications (dApps), manage supported digital assets, and connect with onchain services. If you are getting started, it is important to use official Coinbase resources and carefully review every wallet action before confirming it.

Getting Started With Coinbase Extension

To begin, download the official wallet browser extension through Coinbase's supported setup process. Coinbase's current help documentation explains that the browser extension is designed to work with browsers such as Chrome and can connect a wallet to decentralized applications.

After installing the extension, you can create a new wallet or connect an existing wallet, depending on the available setup options. Follow the instructions displayed by the official extension and avoid downloading wallet software from unofficial websites or unknown links.

For current setup information, visit Coinbase's official wallet resources.

Setting Up Your Wallet

The Coinbase Extension setup may involve creating a wallet, establishing access credentials, and securely backing up your recovery information. If you create a self-custody wallet, your recovery phrase is particularly important because it can provide access to the wallet and its associated assets.

Write down your recovery phrase carefully and store it in a secure location. Never share it with another person or enter it into an unsolicited website, form, email, or message. Coinbase notes that it cannot recover a user's 12-word recovery phrase for them.

You can learn more about wallet security through Coinbase's wallet help center.

Connecting to Decentralized Applications

One of the main advantages of the Coinbase Extension is the ability to connect your wallet to supported decentralized applications. For example, a compatible dApp may request permission to connect to your wallet before allowing you to use a particular feature.

Always check the website address and carefully review connection or transaction requests before approving them. A wallet connection can allow a dApp to see publicly available blockchain information associated with your wallet address.

Coinbase also provides information about dApps and wallet connections to help users understand the differences between Coinbase accounts and self-custodied wallets.

Supported Networks and Assets

The Coinbase Extension supports blockchain networks and assets according to the wallet's current capabilities. Coinbase's documentation lists Ethereum and Solana support for its browser-extension experience, while capabilities can vary by network and wallet version.

Before sending or receiving cryptocurrency, verify that the asset and network are supported. Using an incompatible network or incorrect address can result in funds becoming difficult or impossible to recover.

For current information, review Coinbase's supported networks and assets.

Stay Safe While Using Your Wallet

When using the Coinbase Extension, security should remain a priority. Avoid suspicious websites, fake support accounts, and unsolicited wallet links. Never disclose your recovery phrase or private wallet credentials to someone claiming to provide technical support.

Before confirming a transaction, carefully check the recipient address, network, amount, and any requested permissions. Taking a few extra moments to verify these details can help reduce avoidable mistakes.

With the official extension, secure recovery-phrase storage, and careful transaction review, you can create a safer foundation for exploring onchain applications and managing supported digital assets through your browser.
