EigenLayer allows ERA staking to "enhance security", and ERA can also bring users to EigenLayer - helping each other out, creating a lively atmosphere.
With the Caldera chain connected to EigenLayer, the security level is higher, making users more willing to deposit assets; ERA can earn interest in EigenLayer, and holders are also happy to participate. This kind of "mutual assistance" is stronger than going it alone, with ERA acting like a thread that connects both sides together.
