# Overview

This section covers the SDKs, standalone crates, blockchain interaction, and developer tools for building on the Nym mixnet.

## Start here

If you're new, read **[Choosing an Approach](/developers/integrations)** first. It maps your runtime (native vs browser vs mobile) and your architecture (end-to-end vs proxy) onto the right crate/library.

## Crates/Libraries

| Crate/library | Language | Use it for |
|---|---|---|
| [`nym-sdk`](/developers/rust) | Rust | E2E messaging, `AsyncRead`/`AsyncWrite` streams, client pooling. Start with the [Tour](/developers/rust/tour). |
| [`smolmix`](/developers/smolmix) | Rust | `TcpStream` and `UdpSocket` over the Mixnet via a userspace IP stack. Compatible with `tokio-rustls`, `hyper`, `tungstenite`. |
| [`mix-fetch`](/developers/mix-fetch) | TypeScript | `fetch()`-compatible API for browser HTTP(S) requests over the Mixnet. |
| [TypeScript SDK](/developers/typescript) | TypeScript | Browser-side Mixnet Client (raw messaging) and Nyx Smart Contracts. |
| [Standalone Clients](/developers/clients) | Language-agnostic | SOCKS5 and WebSocket binaries for piping traffic through the Mixnet without an SDK. |

## Other sections

- **[Chain interaction](/developers/chain)**: query Nyx state, submit transactions, and call Nym smart contracts.
- **[APIs](/apis/introduction)**: auto-generated reference for Nym infrastructure HTTP endpoints.
