Coinbase Wallet® Extension® — Secure Crypto Access

What is Coinbase Wallet Extension?

The Coinbase Wallet Extension is a browser-based crypto wallet that allows users to manage their digital assets directly from their preferred browser. Unlike exchange wallets, it gives users full control of private keys, enabling secure interaction with decentralized applications (dApps), DeFi platforms, and NFT marketplaces.

Note: The extension works in tandem with the Coinbase Wallet mobile app but is fully functional as a standalone desktop wallet.

The extension supports multiple cryptocurrencies, ERC-20 tokens, and cross-chain interactions, all while keeping private keys encrypted in your browser storage. Coinbase Wallet Extension offers both convenience and security for everyday crypto transactions.
