Coinbase Wallet Extension — Manage Your Crypto Directly from
Coinbase Wallet Extension: A Secure Self-Custody Wallet for Web3
The Coinbase Wallet Extension is a powerful browser-based crypto wallet designed to give users full control over their digital assets while providing seamless access to the decentralized web. Built by Coinbase, the wallet extension allows users to store cryptocurrencies, manage NFTs, and interact with Web3 applications directly from their browser—without relying on centralized custody.
Unlike the Coinbase exchange account, the Coinbase Wallet Extension is self-custodial, meaning only you control your private keys and funds.
What Is the Coinbase Wallet Extension?
The Coinbase Wallet Extension is a non-custodial browser wallet that connects your browser to blockchain networks such as Ethereum and other EVM-compatible chains. It enables users to safely interact with decentralized applications (dApps), sign transactions, and manage on-chain assets.
Because it is self-custody, Coinbase does not have access to your wallet, private keys, or recovery phrase.

How the Coinbase Wallet Extension Works
The extension acts as a secure bridge between your browser and blockchain networks:

- You review and approve the connection
- Transactions are shown clearly before execution
- You manually confirm every action
No transaction can occur without your explicit approval, ensuring transparency and security.
