What is the Coinbase Wallet Extension?
The Coinbase Wallet Extension is a browser-based self-custody wallet that allows users to interact with the decentralized web (Web3) directly from their browser. It acts as your portal to access decentralized applications (dApps), store crypto assets, send transactions, and collect NFTs — all without giving up control of your private keys.
Built by Coinbase, the extension is available for Chrome, Brave, and other Chromium-based browsers.

Key Features of the Coinbase Wallet Extension
1. Multi-Chain Support
The extension supports Ethereum and EVM-compatible chains like Polygon, Avalanche, Arbitrum, Base, Optimism, and BNB Chain. You can add custom networks manually as well.

4. dApp Integration

5. Sync with Mobile

Coinbase Wallet Extension vs Coinbase Exchange
It’s important to understand that the Coinbase Wallet Extension is not the same as your Coinbase.com account. Here's how they differ:
- Coinbase Wallet: Self-custody wallet – you own your keys
- Coinbase Exchange: Centralized platform – Coinbase holds your keys
Using the wallet extension gives you full control and direct access to the decentralized web.
