struct OffchainData {
    address wrapper; // dfs wrapper address for the aggregator (must be in WrapperExchangeRegistry)
    address exchangeAddr; // exchange address we are calling to execute the order (must be in ExchangeAggregatorRegistry)
    address allowanceTarget; // exchange aggregator contract we give allowance to
    uint256 price; // expected price that the aggregator sent us
    uint256 protocolFee; // deprecated (used as a separate fee amount for 0x v1)

}

struct ExchangeData {
    address srcAddr; // source token address (which we're selling)
    address destAddr; // destination token address (which we're buying)
    uint256 srcAmount; // amount of source token in token decimals
    uint256 destAmount; // amount of bought token in token decimals
    uint256 minPrice; // minPrice we are expecting (checked in DFSExchangeCore)

    address user; // user to check if custom fee is set for the user
