IReactorGateway Interface

Overview

The IReactorGateway interface defines a set of functions designed for managing cross-chain communication, fee handling, and contract state (pause/unpause). It enables sending messages, executing actions from other sources, retrying failed messages, and configuring fee management.

Interface

interface IReactorGateway {
    function execute(bytes32 _id, address _destinationAddress, string calldata _sourceName, string calldata _sourceAddress, string calldata _action, bytes calldata _payload) external;
    function feeManager() external returns (address);
    function pause() external;
    function retry(bytes32 _id, address _destinationAddress, string calldata _sourceName, string calldata _sourceAddress, string calldata _action, bytes calldata _payload) external;
    function send(address _paymentToken, string calldata _destinationName, string calldata _destinationAddress, string calldata _action, bytes calldata _payload, bool _waitForFinality) external payable;
    function setFeeHolder(address _feeHolder) external;
    function setFeeManager(address _feeManager) external;
    function unpause() external;
}

Function Details

execute

function execute(
    bytes32 _id,
    address _destinationAddress,
    string calldata _sourceName,
    string calldata _sourceAddress,
    string calldata _action,
    bytes calldata _payload
) external;

Executes an action received from another chain.

  • _id: Unique identifier for the message.
  • _destinationAddress: Contract address to execute the payload.
  • _sourceName: Name of the originating blockchain.
  • _sourceAddress: Address of the caller on the source.
  • _action: Action to be performed.
  • _payload: Encoded data required to perform the action.

feeManager

function feeManager() external returns (address);

Returns the current address of the fee manager responsible for fee logic.

pause

function pause() external;

Pauses contract operations. Typically used during upgrades or incident response.

retry

function retry(
    bytes32 _id,
    address _destinationAddress,
    string calldata _sourceName,
    string calldata _sourceAddress,
    string calldata _action,
    bytes calldata _payload
) external;

Retries a previously failed message delivery or execution.

  • Same parameters as execute.

send

function send(
    address _paymentToken,
    string calldata _destinationName,
    string calldata _destinationAddress,
    string calldata _action,
    bytes calldata _payload,
    bool _waitForFinality
) external payable;

Sends a message or initiates an action on a destination.

  • _paymentToken: Token used to pay for cross-chain messaging.
  • _destinationName: Target blockchain name.
  • _destinationAddress: Address to invoke on the destination.
  • _action: Action name to be invoked.
  • _payload: Encoded action-specific data.
  • _waitForFinality: Whether to wait for finality before proceeding.

setFeeHolder

function setFeeHolder(address _feeHolder) external;

Sets the address to receive collected fees.

setFeeManager

function setFeeManager(address _feeManager) external;

Updates the address responsible for fee logic.

unpause

function unpause() external;

Resumes normal contract operations after a pause.
