On Day 1, you purchase 2 ETH at a price of 3000, and the last price is 3500. Average cost price Average cost price = (0 + 3000 * 2) / 2 = 3000 PnL = (3500-3000)*2 = 1000 PnL Ratio = (3500 - 3000)/3000 * 100% = 16.67% Cumulative Cost Price Cumulative Cost Price = (3000 * 2 - 0)/2 = 3000 PnL = 3500 * 2 - 3000 * 2 + 0 = 1000 PnL Ratio = 1000 / (3000 * 2 - 0) * 100% = 16.67% Scenario 2: On Day 2, you sell 1 ETH at a price of 3500, and the last price is now 4000.

For example, with a safety order amount = 100 USDT, multiplier = 2. Safety orders will be placed: 100 = (2^0 × 100) 200 = (2^1 × 100) 400 = (2^2 × 100), et cetera Price steps multiplier: Applied to the price step for placing the next safety order. It increases or decreases the price gap between safety orders. For example, with a price step = 1%, multiplier = 2.

Example: If the USDT-USD hedging volume is 10,000,000 USD, and USDT/USD = 0.985 (falling under tier 3), then MR9 is calculated as follows: Tier 1 factor value: 0.5% + (0.99 – 0.985) / 1% × (1% – 0.5%) = 0.75% Tier 2 factor value: 1.5% + (0.99 – 0.985)/ 1% × (2% – 1.5%) = 1.75% Tier 3 factor value: 2% + (0.99 – 0.985) / 1% × (3% – 2%) = 2.5% MR9 = 1,000,000 (max amount considered in tier 1) × 0.75% + 4,000,000 (max amount considered in tier 2) × 1.75% + 5,000,000 × 2.5% = 202,500 USDNote: For each

As specified in number 2, the times of sampling inspections will affect the chance of tampering or manipulation succeeding. 5. Generating low-degree proof: we can control the probability of tampering or manipulation success through sampling inspection. However, there is a condition as mentioned in number 2 that we need to ensure the polynomial degree being verified is not more than the degree of a valid polynomial.
