Wu learned that according to the Arbiscan browser, the SAPCEX equity token deployed by Robinhood, which had previously added a pool and opened trading on DEX, has been changed to Demo 1 Token and has undergone contract upgrades. The current supply has become zero. It should be noted that although deployed by Robinhood, these same named tokens may still be in the testing phase at present. H/T: @0xblanker
