What is USDD?

Collateral issuance

USDD's vault system lets users deposit accepted assets and create stablecoin debt. TRX is among the collateral assets supported by the protocol. Each collateral category has its own borrowing limits, stability fees, and liquidation parameters. The amount a vault can mint depends on its collateral value and existing debt. Vault transactions require TRX to pay network fees.

Debt and liquidation

A vault owner can repay borrowed USDD and withdraw the associated collateral. Full repayment closes the debt position. If the collateral ratio falls below the required minimum, liquidation can begin. The protocol uses collateral auctions and incentives for liquidation participants to cover undersecured debt. Price feeds supply the valuations used to assess collateral positions.

Peg mechanisms

The Peg Stability Module exchanges USDD with supported stablecoins at a one-to-one reference rate. Available balances limit how much the module can exchange. Its documented swaps carry no protocol service fee, although network charges still apply. Market arbitrage complements this mechanism when USDD trades away from its dollar target. USDD can be transferred and used in DeFi, while its issuance follows collateral and debt activity rather than a preset mining schedule.
