Coinbase Extension: Secure Access to Web3 and Your Crypto Wallet
The Coinbase Extension, also known as the Coinbase Wallet browser extension, is a powerful tool that allows users to interact with decentralized applications (dApps), manage digital assets, and explore Web3 directly from their browser. Built by Coinbase, one of the most recognized names in crypto, the extension combines ease of use with strong security standards.
Unlike the Coinbase exchange account, the Coinbase Extension is a self-custody wallet, meaning you control your private keys and funds at all times.
What Is the Coinbase Extension?
The Coinbase Extension is a browser-based crypto wallet designed to connect users to the decentralized web. It supports Ethereum and multiple compatible blockchain networks, allowing users to store tokens, manage NFTs, and interact with DeFi platforms directly from supported browsers.
It operates independently from the Coinbase exchange and does not require a Coinbase.com login to function.

Coinbase Extension vs Coinbase Exchange Account
Many users confuse the extension with the Coinbase exchange. They serve different purposes:
| Feature | Coinbase Extension | Coinbase Exchange |
|---|---|---|
| Custody | Self-custody | Custodial |
| Private keys | You control | Coinbase controls |
| Web3 access | ✅ | ❌ |
| DeFi & NFTs | ✅ | Limited |
| Email/password login | ❌ | ✅ |
The extension is designed for Web3, while the exchange focuses on trading.
Using the Coinbase Extension with dApps
With the extension, users can:
- Connect to decentralized exchanges

Wallet connections can be revoked at any time from the extension settings.
Security Best Practices
To stay safe while using the Coinbase Extension:
