Introduction

As decentralized finance (DeFi), NFTs, and Web3 applications continue to grow, having a secure and flexible crypto wallet is essential. The Coinbase Wallet Extension is a browser-based crypto wallet that allows users to interact directly with decentralized apps (dApps), manage digital assets, and control private keys — all from their browser.

Unlike custodial exchange wallets, Coinbase Wallet Extension is a self-custody wallet, meaning you control your private keys and recovery phrase. It provides the freedom to explore DeFi platforms, NFT marketplaces, and blockchain networks while maintaining ownership of your crypto assets.

Designed for ease of use and strong security, the extension works seamlessly with popular browsers and supports multiple blockchain networks.
