# SDKs

Switchboard SDK versions are pinned and validated in one canonical place:

* [SDK Version Matrix](/tooling/sdk-version-matrix.md)
* Machine-readable lock file: [`tooling/sdk-versions.lock.json`](https://github.com/switchboard-xyz/gitbook-on-demand/blob/main/tooling/sdk-versions.lock.json)

Use the matrix for all docs and code snippets to avoid version drift.
