KuCoin Futures Will Delist the B3USDT, BOBBOBUSDT & DEGENUSDT Perpetual Contracts (2026-04-28)

• Starting from 6:50 on April 28, 2026 (UTC), opening new positions in the above contracts will be suspended, while closing positions will remain unaffected.
• The above contracts will be delisted at 7:00 on April 28, 2026 (UTC).
• Upon delisting, all open orders will be canceled, and positions will be settled based on the average index price over the last 30 minutes prior to delisting. Users are advised to close their positions in advance to avoid potential losses.
• In case of abnormal market volatility or confirmed price manipulation of the index, KuCoin Futures may take additional protective measures without further notice. These may include adjusting the maximum leverage per tier, position value, maintenance margin requirements, updating funding rates (including interest, premium, and capped rates), or modifying the index components.
• Please note that there may be significant price fluctuations prior to the contract delisting. We strongly recommend that users reduce leverage or close positions in advance to manage risk.

Updated Mark Price Mechanism Before Delisting

To enhance fairness and stability during the delisting process, KuCoin Futures has updated the mark price mechanism for the final 30 minutes prior to delisting:

• Mark Price = Average Index Price (calculated every second)
  • Example for a 7:00 delisting:
    • 6:35 mark price = average index price from 6:30 to 6:35
    • 6:59 mark price = average index price from 6:30 to 6:59

• 180-Second Smooth Transition Mechanism

  • Starting from 6:30, the system will smoothly transition from the original mark price formula to the new average-based mark price over a 180-second window to avoid sudden mark price jumps.
    • Mark Price = β * (New Mark Price Formula) + (1 − β) * (Old Mark Price Formula)
