Futures V3 & Futures Testnet — Guarded Cancel Endpoints

  • Added two new TRADE endpoints to Futures V3 and Futures Testnet (EN & ZH), intended for orders placed or authorized on-chain. The on-chain nonce associated with each order is used to guard against duplicate or out-of-order cancellation:
  • DELETE /fapi/v3/guardedCancelOrder (weight 1) — Cancel a single active order. Requires signer, nonce (the nonce used when placing the order, not a fresh timestamp), and signature. Other parameters and response identical to DELETE /fapi/v3/order.
  • DELETE /fapi/v3/guardedBatchOrders (weight 1) — Cancel multiple active orders (up to 10). Requires signer, nonce (the nonce used when placing the batch, not a fresh timestamp), and signature. Other parameters and response identical to DELETE /fapi/v3/batchOrders.
