This smart contract manages arbitrators in the NFT Protect system. It is responsible for adding, deleting, and managing arbitrators.

Arbitrator Registry

{% hint style="info" %} The contract code can be found here. {% endhint %}

Variables

  • counter
    This variable keeps track of the total number of arbitrators added to the registry.
  • arbitrators
    This is a mapping from an arbitrator's ID (a uint256) to an Arbitrator structure, which contains information about the arbitrator.

Arbitrator

The Arbitrator structure contains the following fields:

  • name: The name of the arbitrator.
  • arbitrator: An instance of the IArbitrableProxy interface representing the arbitrator.
  • extraData: Additional data associated with the arbitrator, stored as bytes.

Events

  • Deployed()

This event is emitted when the contract is deployed.

  • ArbitratorAdded(uint256 indexed id, string name, IArbitrableProxy arbitratorProxy, bytes extraData)

This event is emitted when a new arbitrator is added. It includes the ID, name, IArbitrableProxy instance, and extra data associated with the new arbitrator.

  • ExtraDataChanged(uint256 indexed id, bytes extraData)

This event is emitted when the extra data of an arbitrator is changed. It includes the ID of the arbitrator and the new extra data.

  • ArbitratorDeleted(uint256 indexed id)

This event is emitted when an arbitrator is deleted. It includes the ID of the deleted arbitrator.
