Coinbase Extension® — Getting Started

A complete beginner-friendly presentation guide to installing, setting up, and safely using the Coinbase Extension® for seamless crypto management, Web3 access, and decentralized finance interaction.

Installing the Coinbase Extension®

The Coinbase Extension® is a browser-based crypto wallet designed to simplify access to digital assets, decentralized applications, and blockchain networks directly from your browser. Unlike traditional web logins, this extension allows users to interact securely with Web3 platforms while maintaining full control over private keys.

To begin, users must install the extension on a compatible browser such as Google Chrome, Microsoft Edge, or Brave. Once installed, the extension becomes a powerful gateway to the crypto ecosystem, enabling secure authentication without exposing sensitive data.

Supported Browsers

Coinbase Extension® works best on Chromium-based browsers. This ensures optimal performance, smooth transaction approvals, and seamless dApp connectivity.

After installation, a wallet icon appears in your browser toolbar, giving instant access to your crypto assets anytime you browse.

Setting Up Your Wallet

Once installed, the Coinbase Extension® guides users through a straightforward setup process. You can either create a new wallet or import an existing one using a recovery phrase.

Creating a new wallet generates a unique set of cryptographic keys stored locally on your device. These keys grant ownership of your digital assets and must never be shared with anyone.

Recovery Phrase Importance

During setup, you will receive a recovery phrase consisting of multiple words. This phrase is the only way to restore access if your device is lost or replaced.

Write it down offline and store it securely. Coinbase Extension® never stores or transmits your recovery phrase.

After setup, users can instantly receive, send, and manage crypto assets while connecting to decentralized applications with just one click.

Using the Coinbase Extension®

The Coinbase Extension® functions as a bridge between your browser and the blockchain. It allows users to interact with decentralized finance platforms, NFT marketplaces, and Web3 services without relying on centralized logins.

When visiting a supported dApp, the extension prompts you to connect your wallet. Once approved, you can sign transactions securely without revealing private information.

Transaction Confirmation

Every transaction requires manual confirmation within the extension. This ensures transparency and prevents unauthorized activity.

Users can review gas fees, token amounts, and destination addresses before approving transactions.

Security & Best Practices

Security is a cornerstone of the Coinbase Extension®. The wallet operates with a non-custodial design, meaning users maintain full ownership of their funds at all times.

To enhance protection, always lock your wallet when not in use and enable strong device-level security such as PINs or biometrics.

Phishing Awareness

Only connect the extension to trusted websites. Malicious dApps may attempt to trick users into signing harmful transactions.

Avoid clicking unknown links, and never enter your recovery phrase on any website or form claiming to offer support or rewards.

Keeping your browser and extension updated ensures access to the latest security improvements and performance enhancements.
