According to Paolo Ardoino, the upcoming version of Tether's Wallet Development Kit (WDK) will enable developers to build wallets supporting Bitcoin, USDt, XAUt, and USDT0 across all major blockchain networks. The WDK will feature integrated swaps, bridging, DeFi lending, and enhanced multi-device compatibility, all within a fully non-custodial framework. This could significantly lower development barriers and expand trading and DeFi participation, offering traders seamless access to multiple assets and decentralized services in one application (source: Paolo Ardoino via Twitter, April 26, 2025).
