# Development status
The SDK is still somewhat a work in progress: interfaces are fairly stable but still may change in subsequent releases.

In the future the SDK will be made up of several modules, each of which will allow developers to interact with different parts of Nym infrastructure.

| Module    | Functionality                                                                         | Released |
|-----------|---------------------------------------------------------------------------------------|----------|
| Mixnet    | Create / load clients & keypairs, subscribe to Mixnet events, send & receive messages | ✔️        |
| TcpProxy  | Utilise the TcpProxyClient and TcpProxyServer abstractions for streaming              | ✔️        |
| ClientPool| Create a pool of quickly useable Mixnet clients                                       | ✔️        |
| Ecash     | Create & verify Ecash credentials                                                     | ❌        |
| Validator | Sign & broadcast Nyx blockchain transactions, query the blockchain                    | ❌        |

The `Mixnet` module currently exposes the logic of two clients: the [websocket client](../clients/websocket), and the [socks client](../clients/socks5).

The `TcpProxy` module exposes functionality to set up client/server instances that expose a localhost TcpSocket to read/write to.

The `ClientPool` is a configurable pool of ephemeral clients which can be created as a background process and quickly grabbed.
