HTX to Update Assessment and Elimination Rules for USDT-M Futures Market Makers

Dear HTX Market Makers, To optimize platform liquidity and enhance the robustness and sustainability of our assessment framework, HTX will implement a comprehensive upgrade to the assessment and elimination rules for USDT-M Futures market makers, effective May 31, 2026, at 16:00 (UTC). This upgrade introduces a Trading Pair Grouping Management System and a Comprehensive Liquidity Score mechanism. These enhancements are designed to more accurately measure liquidity contributions, incentivize market makers to provide deep and stable liquidity, and ensure a fair and transparent partnership ecosystem. I. Key Updates 1.1 Updated Elimination Rules (USDT-M Futures): Once revoked, users will be ineligible to re-apply for market maker status for three months. This rule will take effect on May 31, 2026, at 16:00 (UTC) and will be reviewed on a monthly basis. 1.2 Assessment Rule Optimization Assets are categorized into four independent groups using a “Level-Up” mechanism. Each group has its own tier structure and maker fee schedule. Qualification for a specific tier is achieved by meeting any one of the criteria within that group. Qualification for a specific tier is achieved by meeting any one of the metrics within that group. USDT-M Futures Group Tier Level-Up Maker Volume Relative to the Platform's Total Maker Volume Weighted Maker Trading Volume Ranking Monthly Composite Liquidity Score Core Tier S ≥ 3% / / Tier 1 [1%, 3%) / / Tier 2 [0.1%, 1%) / / Growth Tier S ≥5% [0, 10%] ≥75 Tier 1 [1%, 5%） (10%, 40%] [45, 75) Tier 2 [0.2%, 1%） (40%, 80%] [15, 45) Watchlist Tier S / [0, 15%] ≥70 Tier 1 / (15%, 45%] [50, 70) Tier 2 / (45%, 80%] [20, 50) Notes: 1.3 Maker Fee Rates (Unchanged) Tier USDT-M Futures Maker Fee Rate (bps) Tier S -1.40 Tier 1 -1.25 Tier 2 -1.00 Notes: 1 bps = 0.01% Market Makers will receive their negative Maker rebates immediately after each trade is completed. Their Taker fee rate is determined by their Prime level on the HTX platform. II.

Cumulative Pending Orders = (Bid + Ask) / 2 within the tier (denominated in USDT). Calculation Examples Example 1 (Final Individual Asset Score within Group): Growth Group — XRP The thresholds for the Growth Group are 300 / 1,000 / 2,000 USDT. Assume that after one month of activity, the market maker’s snapshot data is as follows: Item Data Points per Asset Total Monthly Snapshots (N) 8,640 (5 min intervals × 30 days) 10 0.01% Tier Successes 2,592 (30% success rate) 5 0.05% Tier Successes 4,320 (50% success rate) 3 0.10% Tier Successes 1,728 (20% success rate) 2 Points Calculation: Total Snapshot Points for a Single Asset = 2,592 × 5 + 4,320 × 3 + 1,728 × 2 = 12,960 + 12,960 + 3,456 = 29,376 points Theoretical Maximum Points = 8,640 × 10 = 86,400 points Final Score for a Single Asset = 29,376 ÷ 86,400 × 100 = 34 Example 2: Monthly Composite Liquidity Score There are a total of 6 trading pairs in the Growth Group. The Market Maker (MM) covers 5 of these pairs with exceptionally high quality; each monthly individual asset score is 90 (approaching Tier S standards). Traded Assets = 5; Total Assets in Group = 6; Coverage Rate = 5/6 = 83.3% → Coverage Coefficient = 1.0 Average Individual Asset Score within Group = (90+90+90+90+90)/5 = 90 Monthly Composite Liquidity Score= 90 × 1.0 = 90. → According to the assessment rules, the Market Maker’s result for this level up is Tier S.
