Our verdict on PolkaEx
PolkaEx may interest users looking for a Polkadot-linked exchange and launchpad spanning several networks. Its stated combination of trading and token launches, with Astar identified as its performance layer, is the clearest detail about the product. The main caveat is that current access, supported markets, fees, and launchpad terms are not established. Two audits are listed, but without details that users can assess. Verify the app and contracts before using it.
