Coinbase® Extension | Official Browser Wallet & Web3 Portal

As the world of decentralized finance (DeFi), NFTs, and Web3 applications expands rapidly, having a secure and convenient browser-based wallet is more important than ever. The Coinbase® Extension offers a seamless way to access the decentralized web, manage crypto assets, and interact with dApps — all from your browser.

Built by Coinbase, one of the most trusted names in the crypto space, the Coinbase Wallet Extension allows users to fully control their crypto while exploring the Web3 ecosystem in a safe and user-friendly environment.

🌐 What Is the Coinbase® Extension?

The Coinbase Wallet Extension is a non-custodial browser wallet designed for Chrome, Brave, and other Chromium-based browsers. Unlike the Coinbase exchange, which holds your assets for you (custodial), the extension gives you full control of your private keys and funds.

It enables secure access to thousands of decentralized apps (dApps), NFT marketplaces, blockchain games, and decentralized exchanges directly from your browser, with no intermediaries.
