It has its own problems (based on a side chain of Ethereum). But it's a nice application of smart contracts. There's a contract with inmutable code that creates the yes and no pair for each bet when 1 USDC is deposited and also allows for redemption.

Since the code can't be changed, the funds are not in the hands of the platform owners at any time and it would take corrupting the Polygon network to do a rug pull.

Using USDC or Ethereum/Polygon is cringe. Hope we find a way to achieve something similar in Bitcoin or upper layers.
