The latest USDD Vault Weekly Report gives a clear snapshot of how collateral is positioned across different vault types and the structure tells an interesting story about risk balance and capital efficiency.
TRX-backed vaults continue to dominate overall collateral. TRX-A leads with over $186M in collateral and more than 80M USDD minted, reinforcing its role as the primary engine within the vault system. TRX-B and TRX-C also maintain strong positions, each supporting tens of millions in minted USDD, showing diversified participation across collateral tiers.
One key distinction lies in collateral ratios. TRX-B operates with a lower minimum collateral ratio of 120%, making it more capital efficient, while TRX-C requires 150%, offering a more conservative buffer. These structural differences allow users to choose between efficiency and additional safety margins depending on their strategy.
On the stablecoin side, USDT-A stands out with a 105% minimum collateral ratio reflecting the relatively stable nature of USDT-backed positions. Meanwhile, sTRX-A maintains a higher 150% requirement with a 1% stability fee, positioning it as a more conservative collateral option.
Stability fees across vaults range between 0.5% and 1%, creating predictable borrowing costs while maintaining system sustainability.
Overall, the vault distribution shows a well-layered collateral framework combining scale, diversification, and controlled risk parameters. Overcollateralization remains the backbone of USDD’s stability model, and this week’s figures highlight steady structural balance across the ecosystem.
