3. USTD - Definition, concept & Vision
3.1. USTD definition
3.1.1. What USTD is
USTD is a utility token.
Used for on‑chain yield:
• Holding USTD unlocks automated yield airdrops and lets users move value inside Terra Classic without touching banks or brokers.
Fully collateral‑backed:
• Each USTD is minted only when a user deposits 1 USD‑worth of USDC/USDT, so the token’s value comes from transparent smart‑contract vaults.
Decentralised governance:
• All parameters (collateral pools, yield split, upgrades) are set by open on‑chain votes of Terra Classic validators. No board, no CEO, no corporate treasury.
Why these points matter:
• USTD’s primary function is to give users a self‑custodied, interest‑earning dollar proxy they can spend, trade or collateralise inside DeFi.
• Access to those utilities does not depend on a central manager; it is baked into code that anyone can audit.
• Because the token’s value comes from collateral and smart-contract rules—not from a promoter’s future efforts—USTD fits the legal category the SEC, FinCEN and many state regulators call a utility token.
3.1.2. What USTD is not
USTD is not a security token (Not an “investment contract” under the Howey test).
The U.S. Supreme Court’s Howey test asks four questions. If a token fails any of them it is not a security; USTD fails in at least two:
• Investment of money – The mere act of swapping USDC/USDT for USTD is an “investment of money,” so prong is technically satisfied.
• Common enterprise – Each deposit is isolated and fully collateralised on‑chain. No profit‑sharing pool. Holders do not share in each other’s gains or losses, nor in a central balance sheet. Prong is not satisfied.
• Expectation of profit – Yield is generated by utilizing stablecoin-to-stablecoin liquidity pools. UST Protocol / USTD is not a profit vehicle. Yield is variable and expressly not promised. This prong / question is open for debate but at best is not satisfied,
• Reliance on the efforts of others – After deployment all parameters are governed by validator votes; no central team’s future work is essential to the token’s value. Prong is not satisfied.
Not a “note” under the Reves family‑resemblance test:
• USTD is redeemable on demand for the underlying stablecoin collateral, much like a cashier’s check or stored‑value card—both instruments that U.S. courts have excluded from the definition of a security. USTD therefore sits within the consumer‐payment exception of Reves, not in the “security note” category.
Not a payment stablecoin under the GENIUS & STABLE Acts:
USTD does track the dollar, but:
• It is marketed as a yield‑bearing store of value, not as everyday tender.
• Redemption returns USDC/USDT whose market price can drift off $1.
• There is no legally accountable issuer able to obtain the banking‑style licence the Acts demand.
For these reasons USTD would be classed—if at all—as a non‑payment stablecoin, outside the Acts’ stringent regime.

3.2. Core Principles
Decentralization:
• USTD leverages Terra Classic L1’s decentralized infrastructure. All protocol parameters and upgrades are managed via the Terra Classic on-chain governance process.
Transparency:
• All transactions, collateral management, yield generation, and supply control operations are executed on-chain and are fully auditable.
Automation:
• Smart contracts autonomously manage yield harvesting, distribution, and buyback/burn operations, ensuring continuous optimization without manual intervention.
3.3. How USTD Works
Minting Process:
• Users deposit fiat-backed stablecoins (USDC/USDT) into the UST Protocol integrated within Terra Classic L1. In return, they receive USTD tokens at a 1:1 ratio.
Yield Generation:
• The protocol automatically allocates deposited collateral into stablecoin-to-stablecoin liquidity pools on decentralized exchanges (DEXs) to generate yield from transaction fees and optimized liquidity strategies.
Yield Distribution:
• Automatic Rewards: Once you acquire USTD, you become eligible to receive yield.
• Periodic Airdrops: Approximately 50% of the yield generated is distributed directly to USTD holders as regular on-chain airdrops. This means that USTD holders earn yield simply by holding USTD in their wallets—no additional staking or lock-up is required.

• Reinvestment Mechanism: The remaining yield is used for buyback and burn operations, reducing supply, supporting the peg and building a decentralised collateral reserve.
Redemption:
• USTD tokens can be redeemed at any time by converting them back into their underlying collateral (USDC/USDT) through a fully transparent on-chain process.

3.3. Long-Term Objectives
Scalability:
• Achieve broad adoption by leveraging Terra Classic’s high throughput, low fees, and cross-chain interoperability.
Sustainability:
• Maintain the US Dollar peg and provide consistent yields by dynamically balancing minting/redemption, yield distribution, and supply control mechanisms.
• Expansion of reserves into decentralised assets as we overcollateralise.
Seamless Integration:
• Operate as an integral part of the Terra Classic ecosystem—fully governed by Terra Classic’s decentralized governance—ensuring alignment with the broader community’s interests.
