LayerZero Protocol is an open-source cross-chain communication protocol that enables multiple blockchains to communicate and share information seamlessly. It provides a new way of interacting across chains without requiring a third party to intermediate.

LayerZero mainly makes revenue through transaction fees: LayerZero charges a small fee for each transaction that is processed on its network. This fee is paid by the user who is sending the transaction.

All the fees sent to The Ultra Light Node (v2) [0x4d73adb72bc3dd368966edd0f0b2148401a178e2] is what is counted as revenue.
