# SDKs


The SDK section is split into three categories:

- [Contract SDKs](https://developers.stellar.org/docs/tools/sdks/contract-sdks.md) that are used to build smart contracts that will be deployed to the Stellar network;
- [Client & XDR SDKs](https://developers.stellar.org/docs/tools/sdks/client-sdks.md) that are used by applications to interact with the network;
- [Build your own SDK](https://developers.stellar.org/docs/tools/sdks/build-your-own.md) that details the minimum requirements for building your own SDK.
