South Korean exchanges Upbit and Bithumb will end support for Synthetix (SNX) at 6:00 a.m. UTC on Sept. 28, 2026, equivalent to 3:00 p.m. local time. Upbit will remove the SNX/BTC trading pair under an Aug. 28 notice that converts an Aug. 7 warning-list designation into a firm delisting date. The exchange cited unresolved issues around supply-plan changes, business authenticity, sustainability and project progress, while explanatory materials from the Synthetix foundation did not resolve the investment-warning concerns and a broader review found SNX no longer met continued-trading criteria. Withdrawals remain open for 30 days after the cutoff, through Oct. 28, 2026, with no migration or replacement listing announced.
