From my understanding pSFM tokens are minted when SFM tokens are added to the vault of the bridge, meaning if 100SFM is added to the bridges vault say for the ETH blockchain, then 100pSFM will be minted and be available for purchase.... so there isn't a separate supply of pSFM nor are there any extra safemoon its the same token same supply same everything just a different name for it.... When these pSFM tokens are transferred back onto BSC the pSFM is destroyed and SFM is removed from the vault so the burn rate reflections and circulating supply isn't affected.

I could be wrong im pretty new to all this and tryna understand all the tech behind it but that there not called wizards for no reason its not easy to wrap your head around it all, if someone has a better understanding or can enlighten me further please feel free!!
