I really love the way you made it simple to see the burn proof, and how much is burned in USD and XEN amount. But if I understood correctly the Proof of Burn, it is not the total burn, rather the actual value of the burn on the day.
It would be incredibly helpful to be able to see the total amount, and at the same time, to be able to see the value of the burn based on the day it was burned rather its price today.
If I did not understood the proof of burn wrong, then I would suggest the following improvements:
1- When calculating the proof of burn, check the burned XEN and get a reference of the Price on the day of burn, to calculate the price more accurately. This will be a change from currently showing X amount is burned and displaying the price for today.
2- keep the current UI as is, but add like a collapsable menu for each burn record.
3- when the user collapse a XEN burn record, ie: ethereum burn, polygon burn, etc... The user will be able to see the date of all burns and the price at the time for a better data visualisation of their actions
4- fix the price of burn to show the actual price due to the logic above, instead of the price today (maybe keep the price today and add the burn price, then we can compare between the amount we burned and the burn value vs holding that XEN till today)
