We’ve been busy since Christmas, and we have done a lot since the new year has begun! We mostly focused on the Cardano side, but there were also some improvements to the Ergo side as well. Enjoy the update!

User interface


  • Added all protocol pool positions view;
  • Fixed bugs with fees in all forms;
  • Added a new structure called Currency (on the background, you will not see it in the user interface). It will enable the front-end team to adapt any SDK for the UI development. Swap and Deposit forms now work much faster;
  • Added Token input fractions limitation depending on asset info;
  • Improved internal hook performance;
  • Fixed bugs with form input/output/deposit calculations;
  • Added slick animation to Swap form.



  • Added some use-cases of how to troubleshoot Yoroi Nightly issues.
