There are currently 5,175,000 PAR & 111,793 paUSD minted on Ethereum & Polygon PoS. The borrow rates for theses tokens is currently set to 33.00% per year for PAR & 25.20% per year for paUSD. The protocol therefore generates 1,707,756 PAR & 28,171 paUSD in revenues per year, or around 1,860,000 USD per year.
