# Introduction

Welcome to the documentation for Nym's TypeScript SDK! <br/>

This guide contains valuable information about the various TypeScript SDK modules that facilitate interaction with different components of the Nym stack, including the mixnet, Nyx chain, and Coconut credentials.


### Our other developer guides

If you're new to the Nym ecosystem and aiming to understand the mixnet concept, explore kickstart options and demos, learn network integration, or follow developer tutorials, the [Developer Portal](https://nymtech.net/developers/) is your go-to resource.

For a more in-depth exploration of Nym's architecture, clients, nodes, and SDK examples, we recommend referring to the [Technical Documentation](https://nymtech.net/docs/) section.

If you're looking for information and setup guides for the various pieces of Nym mixnet infrastructure (mix nodes, gateways, network requesters) and Nyx blockchain validators, then have a look at our [Operators Guide](https://nymtech.net/operators/introduction.html).


### What is Nym?
Nym is a **privacy infrastructure that secures user data and protects against surveillance at the network level**.
The platform does so by  leveraging different technological components:
 - **A Mixnet**, a type of overlay network that makes both content and metadata of transactions private through network-level obfuscation and incentivisation (using [Sphinx](https://blog.nymtech.net/sphinx-tl-dr-the-data-packet-that-can-anonymize-bitcoin-and-the-internet-18d152c6e4dc));
- **A blockchain,  [Nyx](https://blog.nymtech.net/nym-is-not-a-blockchain-but-it-is-powered-by-one-4bb16ef16587)**, our Cosmos SDK blockchain, to allow for us to use payment tokens in the form of NYM, as well as smart contracts, in order to create a robust, decentralized, and secure environment incentives for the mixnet;
- **Coconut, a signature scheme** that creates an application-level private access control layer to power [Zk-Nyms](https://blog.nymtech.net/zk-nyms-are-here-a-major-milestone-towards-a-market-ready-mixnet-a3470c9ab10a);
- **A utility token, [NYM](https://blog.nymtech.net/nym-tokens-where-do-they-live-and-how-are-they-distributed-cross-chain-8d134bf9c41f)**, to pay for usage, measure reputation and serve as rewards for the privacy infrastructure.

Simply put, the Nym network ("Nym") is a decentralized and incentivized infrastructure to provision privacy to a broad range of message-based applications and services.

[The Nym network ("Nym")](https://www.feat-nym-update-nym-web.websites.dev.nymte.ch/nym-whitepaper.pdf) is a privacy infrastructure that, simply put, can be seen as a ["Layer 0" privacy infrastructure](https://blog.nymtech.net/nym-layer-0-privacy-infrastructure-for-the-whole-internet-e53238f9b8e7) for the entire internet.
