Fleet SDK

Fleet SDK is the premier JavaScript/TypeScript library for building Ergo applications. Designed for both browser and Node.js environments, Fleet provides developers with intuitive APIs for constructing transactions, interacting with smart contracts, and integrating Ergo functionality into web applications.

The SDK abstracts the complexity of the eUTXO model, offering high-level builders for common transaction patterns while still exposing low-level primitives for advanced use cases. Developers can create multi-asset transactions, interact with dApps, and sign transactions using various wallet integrations. TypeScript support provides excellent IDE integration and compile-time type checking.

Fleet powers many Ergo web applications and dApps, serving as foundational infrastructure for frontend development. The library integrates seamlessly with popular wallet connectors like Nautilus and includes utilities for address validation, token handling, and box selection. Comprehensive documentation and active maintenance make Fleet the recommended choice for JavaScript developers building on Ergo.
