Bitcoin collateralized lending platform Ledn has expanded its offerings by integrating Tether's gold-backed token, XAUT, as a new form of loan collateral. This addition allows users to secure loans using gold, similar to existing options with Bitcoin. Each XAUT token is backed by one troy ounce of fine gold, stored in a Swiss vault, with Tether holding approximately $23 billion in physical gold reserves. The platform now supports XAUT, USDT, and USAT among other assets. Tether's strategic investment in Ledn in November 2025 underscores the growing collaboration between the two entities.
