[DigitalToday reporter Yoonseo Lee] Cryptocurrency exchange Binance will end trading for four spot pairs — QNT/BTC, RPL/USDC, SIGN/BNB and SKL/USDC — on Aug. 7 local time.

Blockchain media outlet U.Today reported that Binance decided to delist the pairs based on the results of a recent review.

The move will take effect at 0300 UTC on Aug. 7. Binance also plans to stop spot trading bot services for the pairs at the same time, and users must update or cancel bots before the service ends.

The company cited user protection and maintaining market quality as reasons for the delisting. The exchange said it regularly reviews all listed spot pairs and removes some based on factors including insufficient liquidity and declining trading volume.

Separately, Binance plans to halt trading for all spot pairs of six tokens — Across Protocol (ACX), Hashflow (HFT), PIVX (PIVX), Vulcan Forged (PYR), Vanar (VANRY) and Viction (VIC) — at 0300 UTC on Aug. 17. Vanar was included because Binance decided not to support its contract conversion plan. Token holders should check not only the trading end schedule but also when deposit and withdrawal support will end.

The schedule will proceed in stages. Deposits of ACX, HFT, PIVX, PYR, VANRY and VIC will no longer be credited to user accounts from 0300 UTC on Aug. 18. Withdrawal support will end at 0300 UTC on Oct. 17. In spot copy trading, spot pairs related to these tokens will be removed earlier at 0300 UTC on Aug. 10.

The impact will also extend to the derivatives market. Binance plans to end futures contract trading for the six tokens at 0900 UTC on Aug. 8, automatically settle open positions and then delist the contracts.

The move is seen as part of a process in which Binance reorganises listed assets across spot trading, automated trading, copy trading and futures, beyond a simple reduction in trading pairs. Users should respond by distinguishing between the trading end date and the time when deposit and withdrawal support stops. In particular, those using automated trading or holding futures positions need to close out in advance of the end dates.

Binance's overhaul appears to be aimed at improving operational efficiency by selecting assets with low trading volume and liquidity. But users are urged to exercise special caution because the end schedules differ across spot trading, futures and automated trading services.
