# SDK

### <mark style="color:blue;">Overview</mark>

The Premia SDK is available in Typescript and is the codebase can be used to query data stored in smart contracts or to modify data on-chain by signing and executing transactions on-chain.

The SDK is separated into three main groups, for simple understanding:

* **Types & Entities**
* **Queries (Reads)**

  Queries only read state from contracts on-chain or subgraphs, never update state.
* **Mutations (Writes)**

  Mutations update the state of a contract on-chain.
