Tether, the world's largest stablecoin issuer, has just announced an open-source wallet development kit (WDK), enabling the integration of non-custodial wallets into apps, websites, and even AI agents.
Tether, the company behind the world's largest stablecoin USDT, officially launched its open-source wallet development kit (WDK) on November 11. This is a modular software development kit designed to simplify the integration of non-custodial wallets for both USDT and Bitcoin into any application, website, and device.
This move is considered an important step by Tether to expand its ecosystem and reach users, especially in the context of fierce competition in the stablecoin market.

WDK is designed not only for individual users but also for “new digital entities” such as AI agents, robots, and autonomous systems. The integration of a non-custodial wallet gives users full control over their digital assets, eliminating the need for third-party custody solutions.
Tether emphasizes the WDK's simple setup process, making integration easier for developers. Tether CEO Paolo Ardoino shared on the X platform that the company's goal is to develop open-source, ultra-modular, highly extensible, and field-tested libraries.
He also affirmed the broad compatibility of the toolkit, from embedded devices, mobile, desktop applications to websites, and even AI agents and robots. Initially, WDK will support Bitcoin and Tether (USDT), but plans to expand to other cryptocurrencies in the future, while providing diverse user interface templates for any platform to build a comprehensive non-custodial user experience.
The launch of WDK comes as Tether dominates the stablecoin market with 124 billion USDT in circulation, accounting for 68% of the market share according to data from CoinGecko. The majority of this USDT is circulating on the Tron and Ethereum networks.
