Coinbase Wallet Extension: Your Easy Access to Web3 and DeFi
As the world of decentralized applications (dApps), NFTs, and DeFi continues to grow, so does the need for user-friendly, secure crypto wallets. While Coinbase is best known as a centralized exchange, its self-custody wallet — the Coinbase Wallet Extension — offers a gateway to the decentralized web right from your browser.
In this post, we’ll explore what the Coinbase Wallet Extension is, how it works, and why it's a powerful tool for navigating the world of Web3.
What is the Coinbase Wallet Extension?
The Coinbase Wallet Extension is a self-custody crypto wallet that allows users to interact directly with blockchain applications from their browser. Unlike your Coinbase account (which is custodial), the wallet extension gives you full control over your crypto assets, including private keys.
Built to support the growing Web3 ecosystem, it allows users to manage Ethereum, Polygon, Solana, and other EVM-compatible tokens, as well as access NFTs and DeFi protocols — all without relying on an exchange or third party.
The extension is available for Google Chrome and Brave browsers.
