What is the Coinbase Wallet Extension?

The **Coinbase Wallet Extension** is a browser add‑on that turns your Chrome (or compatible) browser into a Web3-enabled wallet. Unlike the Coinbase Exchange (a custodial platform), the extension is **non‑custodial**, which means *you* retain control of your private keys and funds.

Through the extension, you can send & receive crypto, connect to decentralized apps (dApps), swap tokens, manage NFTs, and explore DeFi — all without leaving your browser.

Key Features

Self‑Custody & Control

Only you hold your private keys. No third party can access your funds without your authorization.

Multi‑Chain Support

Supports Ethereum, Polygon, Solana, Avalanche, BNB Chain, and other EVM‑compatible networks.

dApp Connectivity

Connect seamlessly to decentralized exchanges (DEXs), NFT marketplaces, and Web3 apps.

Token Swaps

Swap between tokens directly in the extension using built‑in aggregation and liquidity sources.

NFT Management

View, trade, and manage your NFT collections from within the browser.

Ledger & Hardware Wallet Integration

Connect your Ledger device to the extension for enhanced security. :contentReference[oaicite:0]{index=0}
