XEN token has been the highest gas consumer on ETH since past few days causing net deflation for the ETH supply. 

Quick thread on how it works 🧵

Its basically an arbitrage between tx cost to mint+claim vs the amount you tokens you get. 
You can go to their website and mint XEN tokens for free, you have to specify after how many days you want to receive those tokens

- You make one tx which gives u a rank, you specify when you want your free tokens (starting from 1d delay to anything).

- Then after 1d or the time period you entered you can do another tx to claim

The amt of tokens you get is directly proportional to 
- the no of days you are waiting for 
- and a delta, delta being difference between your rank and global rank

Daily token supply has a decay over time. And there's a staking feature as well where you get 20% fixed yield

Basically when you did the first claimRank tx your rank is the global rank then after 1d when you claim your tokens it checks the global rank and if more people tried to mint after you the higher the global rank hence the more tokens you get
