What Is Coinbase Extension?

Coinbase Extension (also called Coinbase Wallet Extension) is a non‑custodial browser wallet that lives inside your toolbar and turns your browser into a Web3 gateway. Instead of logging into an exchange every time, you can send, receive, and store crypto, NFTs, and tokens in a few clicks while you browse. Because it is self‑custody, you keep full control of your private keys and recovery phrase at all times.

Key Features of Coinbase Extension Multi‑chain support: Manage Ethereum, EVM‑compatible networks like Polygon and BNB Chain, and even Solana and SPL tokens from one interface.

Web3 and dApp access: Connect to decentralized exchanges, NFT marketplaces, DeFi platforms, and Web3 games without leaving your browser.

NFT management: View, store, and send NFTs directly in the extension, making it easier to build and manage your collection.

Built‑in swaps: Swap thousands of tokens on DEXes with competitive rates while your keys stay local and encrypted.

Portfolio and analytics: Track balances, recent transactions, and basic performance metrics with a clean, dashboard‑style interface.

Security and Self‑Custody Benefits Coinbase Extension is designed as a self‑custody wallet, so your private keys are generated and stored locally on your device, not on centralized servers. The extension uses encrypted key storage, password protection, and optional biometric support on compatible systems to help protect access to your wallet. Every transaction and dApp connection requires explicit approval, and you can review or revoke site permissions at any time for extra protection against phishing and malicious sites.

How to Get Started With Coinbase Extension To start using Coinbase Extension, install it from the official browser store (such as the Chrome Web Store) and pin it to your toolbar. You can then create a new wallet with a recovery phrase or connect an existing Coinbase Wallet account, after which you’ll set a strong password and configure basic security settings. Once set up, you can fund the wallet, connect to dApps in one click, and sync activity across desktop and mobile for a smoother Web3 experience.

Why Use Coinbase Extension for Web3 Coinbase Extension is ideal for users who want fast, secure access to DeFi, NFTs, and Web3 tools without constantly switching devices or logging into centralized exchanges. Its mix of multi‑chain support, NFT tools, dApp connectivity, and user‑friendly interface makes it a strong choice for both beginners and experienced crypto users who value control over their keys.
