The current OasisDEX contract (0x794e6e91555438aFc3ccF1c5076A74F42133d08D) expires and will automatically shut down on 04-February-2021 at 12:00 AM UTC (2021-02-04 T12:00:00+00:00).
An upgraded version of OasisDEX – OasisDEX 1.1 – will be deployed prior to the old contract’s expiration date. OasisDEX 1.1 implements minimal changes that remove any remaining “admin” functions, including the expiration date.
For the details, please refer to Announcement on OasisDex.com.
