Algorand JavaScript SDK

algosdk is the official JavaScript library for interacting with the Algorand blockchain network. It provides comprehensive functionalities for account management, transaction creation, signing, and submission, as well as querying blockchain data. Designed for both Node.js (requiring v18.0.0 or higher) and modern browsers, the SDK is actively maintained by Algorand, with frequent releases addressing bugfixes, enhancements, and API updates to align with the latest Algorand protocol specifications. The current stable version is 3.5.2. Version 3.x introduced significant breaking changes compared to v2.x, notably requiring explicit named imports for all functions and classes instead of a single default export or namespace object. It also ships with first-class TypeScript support, requiring TypeScript version 4.2 or higher for optimal usage.
