Equipment Bridge

The Equipment Bridge (formerly the Pet Bridge) processes the cross-chain bridging of all Pet and Equipment NFTs.

Chain ID

Bridging Pets is not available directly between Harmony and Klaytn and must go through DFK Chain first. Pets cannot be sent to Harmony. Any Pets sent incorrectly may be permanently lost.

Use the following destination Chain IDs for the Equipment Bridge:

• DFK Chain: 53935

• Klaytn: 8217

Fees

Bridging has a fee associated with each transaction. This fee must be included in the value field of the transaction. The fees for bridging Pets/Equipment are as follows:

• Harmony to DFK Chain: 0.016 ONE

• DFK Chain to Klaytn: 0.03 JEWEL

• Klaytn to DFK Chain: 0.0018 KLAY

Equipment Contract Mapping

Use the following mappings for the _equipmentCore input on the sendEquipment function:

• Weapon: 1

• Armor: 2

• Accessory/Offhand: 3
