USDD

Can this project keep operating and funding itself for years?

USDD held a $0.999 peg across 1.78 billion supply on October 19, 2026. Bluechip reports 97% backing excluding endogenous TRX collateral.12

Can outsiders see and check what the team and the protocol do?

USDD publishes vault addresses and five 2025 audits by ChainSecurity and CertiK. However, Aave V3 receipt tokens remain in externally owned accounts.34

Does the protocol earn real fees or income from use?

Not applicable. Weight 0.08 in the stable asset profile, so it neither lifts nor lowers the score.

Is the technology being built and shipped, and does it matter?

USDD v2 combines multi-collateral vaults, Dutch liquidation auctions, a zero-fee Peg Stability Module, Smart Allocator lending yields, and ERC-4626 sUSDD vaults.56

Who uses, builds and holds it, and how durable is that base?

Circulating supply reached 1.78 billion USDD on October 19, 2026. Over 80% of tokens remain concentrated on Tron DeFi pools.78

Do supply, issuance and unlocks protect holders from dilution?

Minting relies on overcollateralized vaults and 1:1 PSM swaps without venture unlock dilution. Six live contracts across three chains fragment supply.98
