The most notable feature of the Caldera (ERA) project—and one that gives it significant significance in the Web3 world—is that the ERA token is used as a unified fee currency across all rollup chains within the Caldera network, making it easy for users and developers to pay fees regardless of the chain on which they run their applications or assets.
Any interaction or transaction across the Caldera rollup network requires a fee, and this is automatically processed using the ERA token, making the system simpler and more efficient than using separate tokens for each chain.
