# WDK Overview

> Overview of the Utexo Wallet Development Kit — WDK abstractions over RGB asset management and RGB Lightning for wallet builders.

The Wallet Development Kit (WDK) is a set of packages that expose RGB capabilities through standardised wallet abstraction interfaces. Where the `@utexo/rgb-sdk` family targets application developers building end-to-end flows, the WDK targets **wallet infrastructure builders** who already use WDK-compatible account and signing abstractions and want to add RGB support without reimplementing the protocol layer.

## WDK Packages

| Package                    | Platform       | Description                                                   | Status |
| -------------------------- | -------------- | ------------------------------------------------------------- | ------ |
| `@utexo/wdk-wallet-rgb`    | Node.js & Bare | RGB asset management — issuance, transfers, inventory, backup | Stable |
| `@utexo/wdk-rgb-lightning` | Node.js & Bare | RGB Lightning node — channels, invoices, payments             | Alpha  |

Both packages are built on `rgb-lib`, so the on-chain experience — UTXO management, asset state, and RGB operations — is consistent between them.

The packages are currently separate because LDK's `KeysManager` owns its own seed, which conflicts with WDK's convention where the secret manager holds the seed. Consolidation is planned once the required upstream LDK changes land.

## When to Use the WDK

Use the WDK packages when:

* Your application already builds on WDK-style account and manager abstractions
* You want to plug RGB or RGB Lightning into an existing wallet architecture without adopting the full `UTEXOWallet` lifecycle
* You need lower-level control over account management, signing policy, and key derivation

If you are building from scratch, the `@utexo/rgb-sdk` family (`rgb-sdk`, `rgb-sdk-web`, `rgb-sdk-rn`) provides a higher-level API and is easier to integrate end-to-end.
