What happens with my assets if I don't migrate to the new platform?

Any DEX orders will remain open until they are filled or canceled but they will not be visible on the new Galactic Marketplace.

Because of the decentralized nature of the DEX (the original marketplace platform), we cannot cancel orders on your behalf or force you to stop using the old platform. If you wish to delist your orders and migrate to the new platform, please see the article "How to migrate from the DEX to the new Star Atlas Galactic Marketplace?". This can be done even after the old marketplace is retired.
