Coinbase Extension®® — Getting Started | Coinbase Wallet®®
The Coinbase Wallet browser extension is a secure self-custody crypto wallet that allows users to store digital assets, connect to decentralized applications (dApps), trade tokens, and explore Web3 directly from their browser. Unlike a centralized exchange account, Coinbase Wallet gives users full control over their private keys and recovery phrase.
The extension is designed for popular browsers such as Google Chrome, Brave, Edge, and other Chromium-based platforms. It supports Ethereum, Bitcoin, Solana, Polygon, Base, and many additional blockchain networks. Users can interact with NFTs, decentralized finance (DeFi) platforms, and Web3 applications while maintaining ownership of their crypto assets.
What Is Coinbase Wallet Extension?
Coinbase Wallet Extension is a browser-based crypto wallet developed by Coinbase for Web3 access and self-custody asset management. It works independently from a standard Coinbase exchange account, although users can optionally connect both services for easier transfers.
The extension allows users to:
Store cryptocurrencies securely
Manage NFTs
Connect to decentralized apps
Swap supported tokens
Access DeFi protocols
Explore blockchain networks
Sign Web3 transactions directly in the browser
Because it is a self-custody wallet, users remain responsible for protecting their recovery phrase and wallet credentials.
Supported Browsers
The Coinbase Wallet extension is compatible with several desktop browsers, including:
Google Chrome
Brave Browser
Microsoft Edge
Opera Browser
Users should always download the extension from the official Coinbase website or verified browser stores to avoid fake wallet software.

How to Install Coinbase Wallet Extension

Creating a New Coinbase Wallet
When setting up a new wallet, the extension guides users through several security steps.
Generate a Recovery Phrase
The wallet generates a unique recovery phrase, usually consisting of 12 words.
This phrase is extremely important because it:
Restores wallet access
Recovers funds if the device is lost
Provides full control over the wallet
Users should:
Write the phrase on paper
Store it offline securely
Never share it online
Never upload screenshots of it
Anyone with access to the recovery phrase can control the wallet funds.
Create a Password
Users also create a local browser password that helps protect the wallet on that device.
This password does not replace the recovery phrase.
Importing an Existing Wallet
Users who already have a compatible wallet can import it using:
A 12-word recovery phrase
A private key (when supported)
Imported wallets automatically sync balances and supported assets.
