# Submit Signed Orders

> 🚧 We recommend using Reservoir SDK
>
> [Reservoir SDK](https://reservoirprotocol.readme.io/reference/reservoir-sdk-jstsnode) includes helpers that abstract the process of using the Trading API such as iterating through execution steps and returning callbacks that can be used to update your UI. If you are developing in TS/JS we recommend using the ReservoirSDK.
