Open a market on any token
You post the liquidity and keep the edge: traders win and lose against the pool you funded, and you can top it up whenever you like.
Balance-
Any token with a live pool can become a market, on Robinhood Chain or on Solana. The fee is 0.05 ETH and you post at least 0.05 ETH of liquidity, which is what pays traders who win against your pair.
