Upbit has announced it will end trading support for Oasys (OAS). According to the exchange’s statement, the decision was made in line with the assessment of platforms that are members of the Digital Asset Exchanges Joint Advisory Board (DAXA).
The official announcement states that OAS will cease trading on Upbit on March 13, 2026, at 3:00 PM. This will completely end support for OAS/BTC and OAS/USDT pairs. Upon termination of support, all previously placed but unexecuted buy and sell orders for these pairs will be automatically cancelled.
Following this announcement, Upbit emphasized that additional services such as airdrops, wallet upgrades, and hard forks for OAS would also no longer be supported. The exchange reminded users that OAS was previously placed on a “trading alert list” on January 26, 2026, and stated that after review, it was concluded that the risks that led to this alert had not been addressed.
The reasons for the decision included significant shortcomings in Oasys’s roaming plan changes, the procedure for these changes, their transparency, and the level of public disclosure. Upbit stated that this situation could create a risk of harm for users.
On the other hand, Upbit announced that even if support for OAS transactions ends, it will support withdrawals until April 13, 2026 (31 days) to prevent users from being disadvantaged. Users were warned to withdraw their assets from the exchange before the withdrawal period expires.
