# Coinbase Extension® — Getting Started

Learn how Coinbase wallet Extension can simplify digital asset management with convenient browser access, easy navigation, helpful wallet features, and practical everyday tools.

# Coinbase Wallet Extension: Your Browser-Based Crypto Companion

## Bring Wallet Access to Your Computer

The Coinbase Wallet Extension offers a browser-based approach to managing a self-custody crypto wallet. It allows users to access wallet functions while using a desktop browser and can connect with supported blockchain applications. This setup can be helpful for people who prefer a larger computer screen when reviewing wallet information and transaction requests.

## Start With a Secure Setup

Installing the Coinbase Wallet Extension should always be done through an official source. Once installed, users can follow the available setup options to create a new wallet or import a compatible existing wallet. Coinbase's official guide notes that new wallet creation includes a 12-word recovery phrase, which is essential for wallet recovery and must be stored securely.

The recovery phrase should remain private at all times. Users should not type it into random websites or provide it to people offering unsolicited assistance. Losing the recovery phrase can also mean losing the ability to restore access, so secure storage is an important part of wallet preparation.

## Connect With Supported Web3 Apps

A major benefit of a browser wallet is the ability to connect with supported web3 applications directly from a computer. The Coinbase Wallet Extension can act as a wallet interface when compatible websites request access. Users can review connection and transaction prompts before deciding whether to approve them.

The extension also provides ways to work with supported digital assets. Before sending funds, it is important to verify the destination address, network, amount, and other transaction information. Users should also understand that blockchain transactions may involve network fees.

## Build Better Security Habits

A wallet is only as secure as the habits surrounding it. Keep your browser updated, avoid suspicious websites, and download wallet software only from trusted sources. Be especially careful with messages that create urgency or ask for private wallet information.

Coinbase's documentation describes its wallet as self-custody, meaning users maintain responsibility for their recovery information and wallet access.

For users who want desktop access to supported blockchain services, the Coinbase Wallet Extension provides a practical browser-based solution. Learning how wallet recovery works, checking transaction details, and protecting private information can help create a more confident and responsible experience.
