Odaily Planet Daily News: On-chain perpetual contract platform D8X has launched five leveraged order book markets based on Polymarket data on Polygon zkEVM, X Layer and Arbitrum networks. The new markets include predictions such as the results of the US election, the Democratic vice presidential nomination, the Super Bowl champion and the highest-grossing movie in 2024. As a white label engine, D8X provides technical and liquidity support to other developers. To control risks, the platform dynamically adjusts leverage, fees and slippage based on the Polymarket status. (Blockworks)
