0x を動かしてみた　(その5)

0x Protocol の内部データなどを記載してみました

0x order format

address makerAddress;           // Address that created the order.      
address takerAddress;           // Address that is allowed to fill the order. If set to 0, any address is allowed to fill the order.          
address feeRecipientAddress;    // Address that will recieve fees when order is filled.      
address senderAddress;          // Address that is allowed to call Exchange contract methods that affect this order. If set to 0, any address is allowed to call these methods.
uint256 makerAssetAmount;       // Amount of makerAsset being offered by maker. Must be greater than 0.        
uint256 takerAssetAmount;       // Amount of takerAsset being bid on by maker. Must be greater than 0.        
uint256 makerFee;               // Amount of ZRX paid to feeRecipient by maker when order is filled. If set to 0, no transfer of ZRX from maker to feeRecipient will be attempted.
uint256 takerFee;               // Amount of ZRX paid to feeRecipient by taker when order is filled. If set to 0, no transfer of ZRX from taker to feeRecipient will be attempted.
uint256 expirationTimeSeconds;  // Timestamp in seconds at which order expires.          
uint256 salt;                   // Arbitrary number to facilitate uniqueness of the order's hash.     
bytes   makerAssetData;         // Encoded data that can be decoded by a specified proxy contract when transferring makerAsset. The last byte references the id of this proxy.
bytes   takerAssetData;         // Encoded data that can be decoded by a specified proxy contract when transferring takerAsset. The last byte references the id of this proxy.

0x Order Status

INVALID                     // Default value
INVALID_MAKER_ASSET_AMOUNT  // Order does not have a valid maker asset amount
INVALID_TAKER_ASSET_AMOUNT  // Order does not have a valid taker asset amount
FULLY_FILLED                // Order is fully filled
EXPIRED                     // Order has already expired
CANCELLED                   // Order has been cancelled
FILLABLE                    // Order is fillable

0x Order Info

uint8   orderStatus;                  // Status that describes order's validity and fillability.
bytes32 orderHash;                    // EIP712 hash of the order
uint256 orderTakerAssetFilledAmount;  // Amount of order that has already been filled.
