Coinbase 錢包 SDK

Coinbase Wallet SDK is an open-source software development kit designed to enable decentralized applications (dapps) to connect with Coinbase Wallet users across multiple platforms. It supports mobile wallets on Android and iOS, desktop browser extensions for Chrome and Brave, and QR code scanning for desktop connections. This flexibility allows developers to integrate Coinbase Wallet connectivity into their dapps, providing users with a seamless and secure way to interact with Ethereum-based applications.

The SDK offers a straightforward integration process with a JavaScript API that lets developers initialize the wallet connection, request user accounts, and handle wallet events such as account changes, chain changes, and connection status updates. It supports standard Ethereum JSON-RPC methods, enabling dapps to request signatures, send transactions, and interact with smart contracts through the wallet. The SDK also supports deeplinks for mobile dapps, enhancing user experience on mobile devices.

What sets Coinbase Wallet SDK apart is its comprehensive support for Coinbase's ecosystem, including the Coinbase Smart Wallet, and its multi-platform approach that covers mobile, desktop, and browser extension environments. The SDK is actively maintained with clear versioning and migration guides, ensuring developers can keep up with updates and improvements. It is suitable for developers building DeFi platforms, NFT marketplaces, DAOs, and identity/social dapps who want to leverage Coinbase Wallet's user base and security features.

Getting started involves installing the SDK via npm or yarn, initializing it with your app name, creating a web3 provider, and requesting user accounts. The SDK's GitHub repository includes a test dapp for local development and testing. Comprehensive documentation and community support are available through Coinbase's developer portal and Discord server.
