It turns out that OKX's Xlayer and @ katana are both technically supported by @ 0xPolygon! Xlayer was built using Polygon's chain development toolkit CDK and is now running on a CDK-OP Geth compatible with OP Stack Simply put, Xlayer has upgraded to a more flexible and secure architecture, making future interactions smoother and cross chain more convenient Not only OKX, but also many L2 are built using Polygon's CDK OP Stack, such as Katana, Forknet... The latest addition is Xlayer Therefore, mortgaging pol can obtain airdrops of @ 0xMiden @ katana @ Talus_Labs Because Polygon supports multiple technology stacks and can automatically integrate with Aggrayer (Polygon's aggregation layer) to achieve unified liquidity, it has attracted more and more developers to use Polygon's CDK tool After the next upgrade, these chains will all use Polygon's unified cross chain solution. The cross chain transaction fee was directly used to empower Pol tokens, rather than being earned by third-party cross chain bridges
