## Rude:

As the oldest currency in the CroSkull ecosystem, $RUDE has managed to retain its oldest function: to be used as a trading currency. In addition to this, $RUDE will have a lot more use cases, it will be required for leveling together with [$S](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls)[LS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls) and will be essential to grow our [pets](https://croskulls-organization.gitbook.io/croskull/ecosystem/pets) and [EvoSkulls](https://croskulls-organization.gitbook.io/croskull/croskull/what-are-evoskulls) stronger.
