Equipment Bridge (LayerZero)

The LayerZero Equipment Bridge processes the cross-chain bridging of Pet and Equipment NFTs. It is available between DFK Chain and Metis, and between Kaia and Metis only.

The Equipment Bridge is built in partnership with Layer Zero using their V2 Messaging protocol. For more information, visit their documentation at: https://layerzero.gitbook.io/docs/.

Use Layer Zero Scan (https://layerzeroscan.com/) to track the progress of bridged items.
