Introduction to the TypeScript SDK

Getting Started

This page covers the TypeScript / JavaScript version of the ULedger SDK.

The ULedger SDK is a framework for building blockchain applications. Written in TypeScript, this SDK is used to develop applications within the ULedger ecosystem and serves as a powerful tool for interacting with a ULedger blockchain network. It lets you create and manage wallets, as well as sign, submit, and query transactions, blocks, and wallet activity.

By integrating the SDK into your TypeScript or JavaScript applications (for example, in Node.js services or backend APIs), you tap into ULedger’s cryptographic and privacy features. This includes strong encryption with post-quantum–ready primitives, zero-knowledge proof support, and Cross-Merkleization for tamper-evident data anchoring.
