Sea Forged Universe collection on opensea.io.
Each planet of the collection can be available in quantities from one to nine. If a planet is generated in the high resolution with a large land area, then most likely there will be only one instance (due to the longer duration of the calculation process).
The unlockable content of each token contains a link to the package with detailed maps of the token’s planet. The package content is subject to MIT License. Therefore, when you resold a token, you can continue to use its unlockable content.
The example planets of this site are also presented in the collection as nine identical copies.
Possible resolution signatures of maps: (7,8), (7,7), (6,7).
Here are mini-samples of all available tokens.
