Announcement on USDT/TRY Trading Pair Price Abnormality and Resolution

Dear CoinTR Users,

On September 7, 2025, between 23:00 and 23:05 (TRT), our monitoring system detected abnormal price fluctuations on the USDT/TRY trading pair, where some orders were executed at prices significantly deviating from the normal market range. We immediately conducted a thorough investigation, and the issue has since been resolved. Trading has fully returned to normal.

1. Cause of the Abnormality

After urgent investigation by our technical team, the issue was traced to a fault in the core matching engine under specific high-concurrency conditions.
        •        Issue Details: When the primary node of the matching engine went down, a temporary inconsistency occurred in price calculation and order sequencing logic on the backup node. As a result, a very small number of orders were not strictly executed under the “price-time priority” principle, leading to trades at abnormal prices.
        •        Immediate Response: We quickly restored the primary node of the USDTRY matching engine, preventing further impact.
        •        Fixes and Reinforcements:
        •        Enhanced Real-Time Risk Controls: Added an extra layer of price rationality validation in the matching process to ensure multiple checks for every order.
        •        System Capacity Expansion: Urgently scaled up matching engine servers to increase redundancy and prevent latency or downtime under high load.
        •        Data Rollback: All abnormal trade data and candlestick (K-line) data generated between 23:00 and 23:05 will be rolled back to avoid user losses and data distortion.

2. Asset Safety & Compensation Plan

User asset security is our top priority. For all affected orders executed at abnormal prices on the USDTRY pair during the period (23:00–23:05), the following measures will be applied:
        •        Profitable Users: Your profits will remain unaffected.
        •        Full Compensation: Users who fully affected to loss will be fully compensated in USDT for the difference between their executed order price and the fair market price at the time. No action is required from users. We will calculate the compensation for affected orders based on a reference price of 41.30 TRY per USDT. This price was determined by taking the weighted average of the USD/TRY rate across major liquid exchanges at the time the anomaly occurred, ensuring a fair and objective benchmark for all settlements.
        •        Compensation Timeline: All compensations will be automatically calculated and credited to user accounts by September 9, 2025, 24:00 (UTC+3).
        •        Liquidity Reward Activity: CoinTR will additionally launch a reward pool of 13,000 USDT exclusively for affected users. Rewards will be distributed proportionally based on trading volume, with final allocations confirmed and distributed on September 10, 2025.

3. Future Optimizations & Preventive Measures

To prevent similar incidents from recurring, we will implement the following improvements:
        •        System Upgrade: Conduct comprehensive code audits and stress testing of the matching engine under extreme scenarios to ensure stability.
        •        Enhanced Monitoring: Deploy more granular real-time monitoring at the millisecond level for quicker detection and isolation of anomalies.
        •        Architecture Optimization: Advance towards a distributed fault-tolerant matching architecture, ensuring service continuity even in the event of single-node failures.
