Even Blockfolio has not added SOV yet but I have sent a request to them.
I urge the community to do the same, please. If more people request it then it will be added soon.
I have been giving my vote for sovryn to be listed on blockfolio but it seems like we must encourage more users to create a request to the blockfolios. Some people in the trading group of sovryn have been doing the same like me to submit their request to the blockfolio for sure.
