JPYC EX temporarily suspends Ethereum and Polygon issuance reservations
JPYC Inc. temporarily suspended JPYC issuance reservations on Ethereum at 20:34 JST and on Polygon at 22:19 JST while investigating the cause. Ethereum reservations were restored at 23:43 JST and Polygon reservations at 00:22 JST on 2026-09-18. The incident occurred on the day Upbit began JPYC trading, but the reviewed evidence does not establish that the reservation interruption caused the venue-specific price dislocation.
