Coinbase Wallet Extension® — Secure Web3 Wallet for Your Browser

The Coinbase Wallet Extension is a browser-based self-custody cryptocurrency wallet designed for secure access to Web3 applications, decentralized finance (DeFi), NFTs, and blockchain networks. Developed by Coinbase Wallet, the extension gives users full control over their crypto assets, private keys, and recovery phrase.

Unlike centralized exchange wallets, Coinbase Wallet operates as a non-custodial wallet, meaning users maintain ownership and responsibility for wallet security and asset management.

• Store cryptocurrencies securely

How to Install Coinbase Wallet Extension

Step 1 — Visit the Official Coinbase Wallet Website

Open the official Coinbase Wallet website and choose the extension download option for your browser.

Step 2 — Add the Extension to Your Browser

Click the install button and approve the browser extension request.

After installation:

Step 3 — Create a New Wallet

New users can create a Coinbase Wallet directly through the extension setup process.

Anyone with access to the recovery phrase can control the wallet and assets.
