# Welcome

The **Wallet Development Kit *****by Tether***** (WDK)** is Tether's open-source toolkit that empowers humans, machines and AI agents alike to build, deploy and use secure, multi-chain, self-custodial wallets that can be integrated anywhere from the smallest embedded device to any mobile, desktop and server operating system. WDK enables trillions of self-custodial wallets.

WDK provides a set of core libraries that give you the highest level of control and a wide range of user-interface templates and widgets to maximize your development and deployment speed.
