TRC10 下单

步骤说明

步骤一：通过 TronGrid 提供的接口服务触发智能合约创建订单事务（获取 ID）

步骤二：对事务进行签名

步骤三：广播事务

详细文档见 触发合约 和 API签名和广播流程。

合约地址

基础币种为TRC10且报价币种为TRX：4155ac3875ceaf0dfe45fe3ee7312b0994a8894097

合约方法

买入：buyOrder(trcToken,uint256,uint256,uint256)

卖出：sellOrder(trcToken,uint256,uint256,uint256)

参数说明

以下只对调用合约时部分参数进行说明。

call_value

消耗的 TRX 数量，单位：sun。当订单需要消耗 TRX 时必须填入，若数值不正确则可能导致下单失败。

例如：用户希望以10 TRX 每个的价格买入10个 BTT，则此处应该填入100000000。注：1 TRX 等于1000000 sun。

parameter

该字段为合约方法 buyOrder / sellOrder 需要传入的参数。

buyOrder 合约方法共有4个参数需要传入，每个参数都是一个长度为64的字符串，将这四个字符串首尾相连组成该parameter字段。

参数1：所要购买的 tokenID；将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐。

参数2：购买数量；需要补齐精度，将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐

参数3：消耗 TRX 数量；与 call_value 参数取值一致，将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐。

参数4：购买价格；单位 sun，将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐。

sellOrder 合约方法共有4个参数需要传入，每个参数都是一个长度为64的字符串，将这四个字符串首尾相连组成该 parameter 字段。

参数1：所要卖出 tokenID；将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐

参数2：卖出数量；需要补齐精度，将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐。

参数3：收入 TRX 数量；该值必须等于卖出价格乘卖出数量，否则挂单不会成功，单位 sun，将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐。注：1 TRX 等于1000000 sun。

参数4：卖出价格；单位 sun，将该值转换为16进制的数字字符串后，把该字符串之前不足64位字符的部分用0补齐。

call_token_value

消耗 TRC10 token 数量；需要补齐精度。当订单需要消耗 TRC10 token时必须填入，若数值不正确则可能导致下单失败。

例如：用户希望以10 TRX 每个的价格卖出10个 BTT，则此处应该填入100000000。

token_id

需要消耗的 TRC10 token ID。

例如：用户希望以10 TRX 每个的价格卖出10个BTT，则此处应该填入1002000。

示例

用户 TLva2m6sx2Ya44kHUN2GZUF2PT5KcCNNUQ 提交一笔价格为0.54 TRX，数量为20的 TSY 买单
