eTether, the world’s largest stablecoin issuer, has introduced a new open-source Wallet Development Kit (WDK), aimed at enabling businesses and developers to seamlessly integrate non-custodial wallet functionality into various platforms. Announced on November 11, the WDK provides a streamlined approach for adding USDT and Bitcoin wallets to websites, apps, and even AI-driven systems.
According to Tether, this modular toolkit empowers users by allowing full control over their assets without relying on third-party custodial services. The WDK is designed to support a broad range of applications, from embedded devices to mobile platforms, and can also integrate with emerging technologies, including AI agents and robotics.
Paolo Ardoino, Tether’s CEO, emphasized the toolkit’s versatility on social media, highlighting its “super-modular, highly scalable, and battle-tested development libraries” which can be adapted to numerous platforms. Initially, the toolkit will support Bitcoin and Tether’s USDT, with future updates planned to include customizable user interface templates to build diverse non-custodial wallet experiences across all devices.
Tether currently leads the stablecoin market with a substantial $124 billion USDT in circulation, commanding a 68% share among stablecoins, as per CoinGecko data. A significant portion of Tether’s stablecoins circulates across the Tron and Ethereum networks, with recent transactions moving billions of USDT to Ethereum on behalf of major exchanges.
As the stablecoin market evolves, Tether is also investing in its reserves. In October, Ardoino disclosed that Tether holds around $100 billion in U.S. Treasuries, over 82,000 Bitcoin, and 48 tons of gold, strengthening the backing for its vast USDT supply. This move bolsters Tether’s position against competitors, particularly Circle’s USD Coin (USDC), which holds a 20% market share with $37 billion in circulation.
With the WDK release, Tether is doubling down on innovation, focusing on empowering both individual and institutional users with secure, versatile, and adaptable tools to support digital asset management across platforms. This launch could be a significant step in redefining non-custodial wallet technology and broadening digital asset accessibility worldwide.
