The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain
The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. The launch tax hook's current buy and sell rates, its decay schedule, and a projection of where the rate is headed. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.
