/**
 * @title    State Chain Utils Contract
 * @notice   Contract that allows users to deposit assets into Chainflip contracts (Vault,
 *           State Chain Gateway or other) and perform arbitrary calls to the State Chain
 *           in a single transaction. The arbitrary call to the State Chain is a `bytes`
 *           parameter that will be interpreted by the State Chain.
 * @dev      There is a function for each contract (Vault, State Chain Gateway) to make
 *           the engine's witnessing and parsing of events easier and less prone to error.
 *           Also to guarantee that FLIP is transferred to the SCGateway contract.
 *           We emit both the msg.sender and tx.origin to give the maximum amount of
 *           flexibility to the State Chain to execute the call.
