USDD Overview
USDD (USDD) is tracked under usdd. The local profile associates it with Stablecoins, USD Stablecoin, BNB Chain Ecosystem, Avalanche Ecosystem. The source profile maps it to tron, bittorrent, ethereum.
Asset Role and Supply
Its core analytical question is peg quality, reserve or collateral design, and redemption access rather than directional momentum. The reviewed record shows circulating supply about 1.50 billion USDD, total supply about 1.50 billion USDD. It records no hard maximum. Supply fields may change through issuance, burns, migrations, or source revisions and should be checked against project records.
Market Structure
At the 2026-09-12 review, the local snapshot placed USDD at market-cap rank #55, with market capitalization about $1.50 billion and reported 24-hour volume of $3.43 million. These values describe observed scale and turnover, not fair value or guaranteed executable liquidity.
YearBull Perspective
YearBull classifies this asset in the stable or pegged bucket. It is excluded from the analytical YearBull Rank, Bull Score, Risk, and Cycle sequence; internal sentinel values are classification markers, not rankings.
Key Risks
Material risks include peg deviation, reserve quality, redemption limits, issuer or governance concentration, and regulatory change. Historical prices, rankings, and classifications do not predict future performance. Verify contract addresses, network support, custody, and venue availability before acting.

USDD: collateralized vaults, conversions and liquidation mechanics
USDD is a collateralized stablecoin system whose documentation connects minting to vault debt, collateral ratios, liquidation rules and a stablecoin conversion module.
Minting begins with a collateralized vault
USDD documentation describes minting through vaults. A user selects an accepted collateral type, deposits collateral and creates USDD as debt against that position. This means newly minted USDD is not documented as appearing independently of the protocol’s collateral system. Its creation is linked to a vault whose health changes with the value of the deposited assets and the amount owed.
The vault structure gives users liquidity without requiring the collateral to be sold, but it also creates obligations. The borrower must monitor the position and its collateral ratio. A stable target price for USDD does not make the collateral static or remove debt risk. The protocol’s design depends on collateral remaining sufficient under its rules while market values can move.
Repayment releases collateral
USDD documentation describes repayment as the route for clearing vault debt and unlocking collateral. The user returns the USDD owed under the vault’s conditions, including any applicable protocol charges, before recovering the collateral that secured the position. Minting and repayment are therefore two sides of one debt lifecycle rather than unrelated token operations.
Repayment does not by itself erase risks that arose while the vault was open. If collateral value falls far enough before the debt is cleared, liquidation rules may intervene. Users also depend on the relevant contracts, price inputs and transaction execution. The documented ability to repay and withdraw should be understood as a protocol mechanism, not a promise that collateral will remain available under every market condition.
The Peg Stability Module
The Peg Stability Module, or PSM, provides a separate conversion route between USDD and USDT. Official material presents this mechanism as part of the system’s effort to support liquidity and the target relationship with the US dollar. It differs from vault minting because it exchanges one supported stablecoin for another rather than creating debt against a volatile collateral position.
A conversion module adds dependencies of its own. Its operation relies on the PSM contracts, available stablecoin liquidity and the assets accepted by the module. USDT also has issuer and market risks outside the USDD protocol. The existence of a documented conversion path should therefore not be read as a guarantee that every amount can always be converted instantly at an unchanged economic cost.
Over-collateralization and liquidation
USDD’s security documentation describes over-collateralization and automatic liquidation of vaults that fall below required thresholds. Over-collateralization is intended to provide a buffer between collateral value and issued debt. Liquidation is the enforcement mechanism intended to recover debt when that buffer becomes inadequate. Together they define a risk-management design, but neither prevents collateral prices from moving abruptly or contracts from failing.
Liquidation protects the wider accounting system by closing unhealthy positions, yet it can impose losses on the vault owner. Auction or sale processes may also behave differently during stressed liquidity. An article about USDD should therefore distinguish system-level stability tools from user-level safety. A mechanism designed to reduce bad debt can still liquidate an individual position when its collateral ratio breaches protocol rules.
Contract identity, risks and unknowns
Official documentation publishes a Tron contract address for USDD, and the corresponding explorer entry provides an independent identity reference. Exact contract verification is essential because USDD documentation lists assets and components across more than one network. A ticker or wallet label alone cannot establish that a token is the intended deployment, particularly when older versions or unrelated copies may remain visible.
USDD remains exposed to collateral volatility, liquidation execution, stablecoin counterparty risk, smart contracts, governance choices, oracles, liquidity and network operation. Current collateral types, ratios, fees, module limits and contract addresses are time-sensitive. The evidence explains how vaults, repayment, the PSM and liquidation are documented to work; it does not establish permanent price stability, guaranteed redemption or immunity from insolvency and technical failure.
Key takeaways
- USDD minting is documented as debt created against collateralized vaults.
- Repaying vault debt unlocks collateral if liquidation has not already intervened.
- The PSM supplies a USDD/USDT conversion mechanism distinct from collateralized minting.
- Over-collateralization and liquidation are risk controls, not guarantees against loss.
- Contract identity and all live vault parameters require current verification.
YearBull Rank context
YearBull Rank data is not available at the moment for usdd.
Rank change (daily snapshots).
Reading rule: lower is better in this ranking.
- 7d window: current rank not available.
- 30d window: current rank not available.
YearBull Rank is a relative ranking on YearBull designed to compare coins on a common scale and time window. Lower rank numbers indicate stronger placement in the current snapshot. Treat it as a directional context tool rather than a standalone verdict.
Rotation context: If the 7d is weak but 30d is strong, it can be a pullback in an up-phase.
Execution context: If rank moves sharply, it may reflect venue mix changes rather than fundamentals.
Risk view: If the last month is chaotic, widen the lookback before concluding.
Turnover context: If the line flatlines, the coin may be moving with its liquidity peers.
Practical note: direction and persistence matter more than the last tick.
