South Korean cryptocurrency exchange Upbit announced that it will terminate trading support for SOPH starting at 3:00 PM KST on November 16, 2026, due to issues with SOPH's information disclosure and circulating supply management. Upbit stated that SOPH failed to timely disclose important information through appropriate electronic mediums and exhibited multiple deficiencies in the transparency and reasonableness of changes to its circulating supply plan, which could potentially harm users. After the termination of trading support, Upbit will continue to support withdrawals for 30 days, until December 16, 2026.
