Reactor Gateway

The Gateway is the public on-chain message submission interface. Normal integrations use two functions:

interface IReactorGateway {
    function feeManager() external view returns (address);
 
    function send(
        address _paymentToken,
        string calldata _destinationName,
        string calldata _destinationAddress,
        string calldata _action,
        bytes calldata _payload,
        bool _waitForFinality
    ) external payable;
}

feeManager() returns the current pricing contract. send(...) accepts a supported payment token (address(0) for native gas), destination, action, ABI payload, and finality preference. When paying with native gas, attach at least the value returned by getSendFee; token payments require the appropriate allowance.

The public Solidity SDK intentionally omits execution, retry, pause, configuration, role, and other protocol-operator functions. Application contracts should not depend on those administrative surfaces.
