HOP is a precision prediction market on Robinhood Chain, an EVM L2 with chain id 4663. You forecast the exact price of a stock, a crypto asset or a chain meme, you stake USDG on it, and your share of the pot depends on how close you land.
Nobody is simply right or wrong here. A forecast that misses by a little earns a little less, and a forecast that misses by a lot earns a lot less, on a smooth curve with no cliff anywhere on it. That is the whole difference from a yes or no market: the answer is a number, so the payout is a distance.
Every pool names one symbol and one close time. You commit before the close, you can change your mind at a cost, and at the close the pool settles and pays out on its own.
