What this means for the ecosystem
USDD’s multi-vault structure allows participants to choose between:
✔ Higher safety vs higher efficiency
✔ TRX or USDT-backed strategies
✔ Variable collateral ratios based on risk tolerance
✔ Transparent, on-chain stablecoin issuance
This layered approach strengthens USDD’s resilience while giving users flexibility in how they deploy capital.
As these vaults grow, they collectively reinforce USDD’s role as a core stablecoin primitive across DeFi on TRON supporting lending, mining, payments, and yield strategies.
