Coinbase® Extension® | Getting Started: Wallet Extension for Web3

As the decentralized web continues to grow, browser wallet extensions have become the bridge to blockchain-powered applications. The Coinbase® Extension®, also known as the Coinbase Wallet Extension, is your portal to the world of DeFi, NFTs, and dApps—right from your Chrome browser.

Whether you're minting NFTs on OpenSea, swapping tokens on Uniswap, or exploring Web3 games, the Coinbase Wallet Extension offers a secure and seamless user experience. With its simple interface and direct integration with Coinbase.com, it is designed for both crypto newcomers and experienced users.

✅ What is the Coinbase Wallet Extension?

The Coinbase Wallet Extension is a self-custody crypto wallet that allows you to access Ethereum and other EVM-compatible blockchains through your web browser. Unlike the main Coinbase app (a custodial exchange), the wallet extension gives you full control over your private keys and digital assets.

Once installed, the extension enables you to:

• Connect to decentralized applications (dApps)
• Send and receive cryptocurrencies
• Store NFTs and tokens
• Interact with smart contracts
• Access DeFi tools like swaps, staking, and lending

Unlike centralized exchanges, your private keys are encrypted and stored locally in your browser—giving you complete ownership.
