最近几天在对接USDT钱包，遇到一个问题就是根本没办法通过omni 钱包提供的API来实现钱包归集，因为API提供的接口都需要发送USDT的地址有一定的BTC数量才可以发送交易，所以没办只能找其他方案替代，请教了其他人后才知道只能通过创建BTC的原生交易才能达到这个效果，折腾了好几天，终于把这个流程给整理通顺了，估计还有很多人会遇到这个问题，所以记录下来为后面的人节省一些时间。
1、准备两个地址
首先两个地址, 发送USDT（地址里面要有USDT，这里通常可能是交易所用户的USDT钱包地址）地址和付手续费的地址（地址里面要有足够的BTC，这里通常可能是热钱包地址）
本次案例中
发送USDT地址为： mn7w1M4fwJzRr4zYy5dMSSfBg1ZC9e4xH4
付手续费地址为： muPuXyRqLBRf8Xyj28d2As8ya4iaw8XWGe
接收USDT地址为：muPuXyRqLBRf8Xyj28d2As8ya4iaw8XWGe
2、分别找到发送地址 和热钱包地址的一笔UXTO 作为发送USDT交易的载体
指令：listunspent 0 999999 '["mn7w1M4fwJzRr4zYy5dMSSfBg1ZC9e4xH4"]'
得到UXTO:
{
"txid": "7ef4ca48422fbd055eb7375145cb59bdadaba13caf29b4279c506a7ba846a33e",
"vout": 0,
"address": "mn7w1M4fwJzRr4zYy5dMSSfBg1ZC9e4xH4",
"scriptPubKey": "76a914486e3cf761cc47642135140da02669c04dd2451088ac",
"amount": 0.00081189,
"confirmations": 31103,
"spendable": true,
"solvable": true
}
指令：listunspent 0 999999 '["muPuXyRqLBRf8Xyj28d2As8ya4iaw8XWGe"]'
得到UXTO:
{
"txid": "0b381b15082156911ca8db2761910fe9545356778d70dd09be30fc0bece9ed9d",
"vout": 1,
"address": "muPuXyRqLBRf8Xyj28d2As8ya4iaw8XWGe",
"account": "sys",
"scriptPubKey": "76a914983c8b990aef5747bdef1f2bf3a49d29b19ae15788ac",
"amount": 0.00992750,

}
