# SDKs

**Who this is for:** developers looking for an installable package. Lumia does not currently publish a general-purpose "Lumia SDK." What exists is a set of reference smart-contract implementations and the underlying Polygon CDK repos Lumia is built on: listed below, nothing implied beyond it.

### What exists today

| Item                         | Status                                                                            | Notes                                                                                                                                                                                                                             |
| ---------------------------- | --------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Tokenization SDK             | Does not exist.                                                                   | Named in Lumia's public materials as a future item, not a shipped product.                                                                                                                                                        |
| LumiaPaymaster               | Foundry-based reference implementation, not a published npm/package SDK.          | ERC-4337 paymaster reference contract; deployed per-integrator via a Foundry script, no single canonical instance. See [Contract Addresses](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/reference/contract-addresses).         |
| LumiaAccountFactory          | Same as above: reference contract, deploy-via-script model, not a package.        | Account-abstraction smart-account factory.                                                                                                                                                                                        |
| Particle Connect integration | Third-party wallet/AA SDK integration guide exists                                | See [`/build/account-abstraction/particle-connect`](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/build-on-lumia/account-abstraction/connect-wallets-with-particle-connect): that page owns the integration steps, not this one. |
| Underlying Polygon CDK repos | Exist and are public, but are Polygon/CDK infrastructure repos, not a "Lumia SDK" | Full list and links: [`/build/cdk-repos`](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/build-on-lumia/cdk-repositories), which owns that content, not duplicated here.                                                          |

No dedicated Lumia client library (JS/TS/Python/Go) is published on docs.lumia.org. If one exists, it belongs on this page.
