1. Core risk classification and response measures

1. Price decoupling risk (the most critical)

- Risk points: Severe market fluctuations causing USDD price to deviate from 1 dollar, triggering panic selling/run

- Official response:

- PSM module: USDD and USDT/USDC 1:1 lossless zero slippage exchange, automatic arbitrage correction

- Dynamic collateral rate: Maintaining a collateral rate of ≥120% in the long term, reserving ample safety margin

- Multi-chain deployment: Dual-chain operation on Tron + Ethereum, expanding arbitrage liquidity

- User operation: Profit through PSM arbitrage when prices deviate, while helping to stabilize prices

2. Collateral risk (systemic risk)

- Risk points: Collateral assets (TRX/BTC/USDT) depreciate sharply, causing collateral ratios to fall below safety thresholds

- Official response:

- Automatic liquidation mechanism: Collateral ratio <**110%** triggers liquidation, auctioning assets to ensure debt repayment

- Asset diversification: Collateral combinations include stablecoins + mainstream crypto assets to reduce correlation risk

- Smart allocator: Reserve funds directed towards low-risk DeFi protocols to enhance safety margins

- User operations:

- Maintain collateral ratio >130% (20% above liquidation line)

- Timely supplement collateral or repay debt to avoid passive liquidation

3. Liquidity risk

- Risk points: Under extreme market conditions, PSM or trading market liquidity may dry up, making normal arbitrage/redeem impossible

- Official response:

- TRON DAO Reserve: Establish a large emergency reserve to respond to liquidity shocks

- Multi-platform access: Full deployment on mainstream exchanges + DeFi protocols to diversify liquidity risks

- Tiered liquidity management: PSM prioritizes small transactions, large transactions enable dynamic fee rate mechanisms

- User operations: Avoid large single transactions, split into smaller operations; prioritize using PSM rather than DEX for pegging trades

4. Smart contract and security risks

- Risk points: Contract vulnerabilities, hacker attacks, and failure of permission management leading to fund loss

- Official response:

- Third-party audits: Institutions like ChainSecurity conduct comprehensive audits of USDD 2.0 contracts, with high security ratings

- Multi-signature management: Core operations require ≥2/3 signatures, no single entity controls funds

- Emergency suspension mechanism: In extreme situations, contracts can be temporarily frozen to prevent losses from expanding

- User operations: Use the official recommended wallet; for large funds, use hardware wallets + multi-signature protection

5. Governance and decentralization risks

- Risk points: DAO governance failure, centralized decision-making, improper parameter adjustments

- Official response:

- Decentralized governance: TRON DAO token holders vote to determine core parameters (collateral ratio/liquidation threshold)

- Transparent mechanism: All reserves, transactions, and voting records are fully on-chain, publicly verifiable

- Governance incentives: Participate in governance to receive additional rewards, enhancing community engagement

- User operations: Actively participate in governance voting, pay attention to parameter adjustment proposals

6. Regulatory and compliance risks

- Risk points: Regulatory policy changes affect stablecoin operations and even ban trading

- Official response:

- Compliance framework: Follow relevant regulations on crypto assets in various regions and actively communicate with regulatory agencies

- Non-custodial design: Users have complete control over assets, with no freezing authority, reducing compliance risks

- Cross-chain compatibility: Ethereum deployment expands compliance coverage

- User operations: Monitor regulatory dynamics, reasonably diversify asset allocation, and avoid excessive concentration of a single asset

7. Liquidation risk (user level)

- Risk points: Market flash crashes lead to user CDPs being liquidated, causing losses of collateral assets

- Official response:

- Liquidation protection: Set a liquidation buffer period to give users time to provide additional collateral

- Minimum liquidation amount: Avoid frequent liquidations of small CDPs, reduce system burden

- Liquidation rewards: Incentivize liquidators to participate and improve liquidation efficiency

- User operations:

- Set price alerts; handle promptly when collateral ratio approaches 120%

- Adopt hedging strategies (such as shorting collateral asset futures) to reduce liquidation probability

II. Key upgrades to enhance USDD 2.0 stability

1. Over-collateralization reinforcement: Increase from a base of 110% to ≥120%, thickening the safety cushion

2. PSM 2.0: Supports USDT + USDC dual stablecoin swaps, liquidity doubled

3. Smart allocator: 50% of the profits generated from reserves will supplement reserves, 50% will be user dividends, forming a positive cycle

4. Multi-chain collaboration: Ethereum + TRON cross-chain bridge optimization to reduce cross-chain risks and costs

5. Risk reserve: Independently set a **5%** issuance volume risk reserve to respond to extreme situations

III. User stability self-checklist ✅

Check items safety threshold operation suggestions

Collateral ratio >130% supplement collateral or repay debt

Asset allocation USDD ≤ 30% of total crypto assets to diversify risks and avoid over-concentration

Trading channels prioritize PSM to avoid high slippage trading on DEX

Wallet security hardware wallet + multi-factor verification to prevent private key leakage

Market monitoring price deviation >0.5% triggers attention prepare to stabilize through PSM arbitrage

IV. Emergency plans for extreme situations

1. Mild depegging (0.98-1.02 USD): Conduct 1:1 swap arbitrage through PSM while helping to stabilize prices

2. Moderate depegging (0.95-0.98 or 1.02-1.05 USD):

- Hold USDD: Wait for PSM liquidity to recover or directly exchange for USDT

- Hold collateral: Increase collateral ratio to over 150% to avoid liquidation

3. Severe depegging (<0.95 or >1.05 USD):

- Prioritize ensuring fund safety; convert some assets into other stablecoins

- Closely monitor TRON DAO announcements and participate in community governance to stabilize the market

V. Summary of stability guarantees

The stability of USDD is built on a triple guarantee of mechanism + market + community:

1. Mechanism guarantees: Over-collateralization + PSM arbitrage + liquidation risk control, building a mathematical stability foundation

2. Market guarantees: Multi-chain liquidity + arbitrage participation to form a self-repairing ecosystem

3. Community guarantee: DAO governance + transparent mechanism to establish a foundation of trust.
