Coinbase Wallet Extension

Your self‑custody browser wallet for Web3 and dApp access

What Is Coinbase Wallet Extension?

The **Coinbase Wallet Extension** is a browser‑based, non‑custodial wallet that allows you to manage crypto assets, NFTs, and interact with decentralized applications (dApps) directly from your browser. You retain full control of your private keys—Coinbase never has access to them. :contentReference[oaicite:0]{index=0}

Unlike Coinbase (the exchange), which is custodial, the extension is designed for Web3 users who want autonomy, security, and direct interaction with decentralized protocols. :contentReference[oaicite:1]{index=1}

The extension supports Ethereum and other EVM-compatible chains, NFT integration, token swap, and synchronization with the Coinbase Wallet mobile app. :contentReference[oaicite:2]{index=2}
