According to Cointelegraph, Tether, the leading stablecoin issuer, has unveiled an open-source Wallet Development Kit (WDK) aimed at facilitating the integration of non-custodial wallets into various platforms. Announced on November 11, the WDK is a modular software development kit designed to empower businesses and developers to seamlessly incorporate non-custodial wallets and user experiences for USDT and Bitcoin across apps, websites, and devices.

The WDK is crafted to accommodate both human users and digital entities such as AI agents, robots, and autonomous systems. Key features include granting users complete control over non-custodial assets, eliminating the need for third-party custody solutions, and offering a simplified setup process. Tether's CEO, Paolo Ardoino, emphasized the focus on creating open-source, highly scalable, and modular development libraries that are easy to integrate across various platforms, ranging from embedded devices to mobile applications, websites, and AI systems.

Initially, the WDK will support Bitcoin (BTC) and Tether (USDT), with plans to expand and provide UI templates for any platform to build diverse non-custodial user experiences. Tether, with a circulation of $124 billion USDT, holds a dominant 68% market share among stablecoins, as reported by CoinGecko. A significant portion of these stablecoins, approximately 120 million, are distributed between the Tron and Ethereum networks. Recently, Tether transferred over 2 billion USDT to Ethereum on behalf of a major exchange transitioning its holdings from cold wallets to Ethereum.

In late October, Ardoino disclosed that Tether's reserves include about $100 billion in US Treasurys, over 82,000 Bitcoin, and 48 tons of gold, backing its stablecoin. Tether's main competitor, Circle, holds a 20% market share with nearly $37 billion in USD Coin (USDC) in circulation.
