Coinbase Extension – Explore the Power of Web3

The Coinbase Wallet Extension is a powerful browser-based crypto wallet that allows users to access decentralized applications (dApps) and manage digital assets directly from their desktop browser. Created by Coinbase, a leading name in the cryptocurrency industry, this extension bridges the gap between your wallet and the decentralized web — securely and conveniently.

What Is the Coinbase Extension?

The Coinbase Wallet Extension is a browser plugin designed to let users store, send, receive, and swap crypto assets while interacting with decentralized applications. It serves as a secure gateway to the Web3 ecosystem, enabling users to participate in DeFi, NFT marketplaces, and other blockchain-based services without giving up control of their private keys.

Unlike the Coinbase exchange app, which is custodial, the Coinbase Wallet Extension is a **non-custodial** wallet. This means you — and only you — control your private keys and funds. Your assets are stored locally on your device, ensuring complete ownership of your digital identity and crypto holdings.

Key Features of Coinbase Wallet Extension

• Full control of your crypto: A non-custodial wallet where you manage your private keys.
• Multi-network support: Works with Ethereum, Polygon, Base, and other EVM-compatible blockchains.
• dApp connectivity: Easily connect to Web3 apps, DeFi protocols, and NFT platforms.
• Secure design: Encrypted storage and backup through recovery phrases.
• Token swaps: Exchange cryptocurrencies directly within the extension.
• Cross-device sync: Pair with the Coinbase Wallet mobile app for seamless portfolio management.
