Omni链USDT交易全流程

# Omni链 USDT 交易全流程

目标:

使用命令行, 构造一笔USDT原始交易转账1个USDT, 并使用第3个地址来支付BTC矿工费。

准备如下:

地址	描述	余额
1Ggbcnw6uo45zBMP1AZVYkLStzwcajSwfq	从该地址转出USDT	9 USDT & 0.00000546 BTC
1P9oRFKX6StetGwDnQ5oAYA7HACFfruQXP	使用该地址接收USDT	--
19gcfLWRcLHpsnR4bJzhUDhBm4FYNdZ5eZ	使用该地址支付手续费	0.00089454 BTC

# 交易形态

目标的交易将会有 2个交易输入，3个交易输出。

# 交易输入

序号	金额	描述
0	0.00000546	转出USDT的地址的一笔unspent
1	0.00089454	用于支付BTC矿工费的unspent

注意这里的交易输入, 第一笔用来标记USDT转出方, 所以第一笔必须是USDT转出方的unspent
后面的unspent不受限制

# 交易输出

序号	地址	金额	描述
0	支付BTC矿工费的地址	待计算	得到交易的找零
1	(可选)特殊的: 转出USDT的地址	0.00000546	转出地址仍有USDT余额，为方便以后继续转出，所以这里为它添加一笔UTXO
2	接受USDT的地址	0.00000546	得到最小交易额的BTC
3	--	0	Omni交易的payload

交易输出同样有顺序要求, 除开payload, 最后一个地址代表转入方

# 准备unspent

https://bitcoincore.org/en/doc/0.18.0/rpc/wallet/listunspent/

按照交易输入的规划，先列出计划的2笔unspent

[root@d0ea558e20d3 bin]# ./omnicore-cli "listunspent" 1 9999999 "[\"1Ggbcnw6uo45zBMP1AZVYkLStzwcajSwfq\",\"19gcfLWRcLHpsnR4bJzhUDhBm4FYNdZ5eZ\"]"

# 准备payload

https://github.com/OmniLayer/omnicore/blob/master/src/omnicore/doc/rpc-api.md#omni_createpayload_simplesend

这里希望转账1个USDT, USDT在omni中的代号是31 所以生成payload如下:

[root@d0ea558e20d3 bin]# ./omnicore-cli "omni_createpayload_simplesend" 31 "1"
000000000000001f0000000005f5e100

# 计算手续费

# 计算size

2笔输入，4笔输出，那么按照通常的size计算公式就是

size = from * 148 + to * 34 + 10
     = 2 * 148 + 4 * 34 + 10
     = 442

# 获取千字节费率

https://bitcoincore.org/en/doc/0.18.0/rpc/util/estimatesmartfee/

第2个参数代表我们希望 2个块内被确认，可以用它来控制交易速度

[root@d0ea558e20d3 bin]# ./omnicore-cli estimatesmartfee 2
{
  "feerate": 0.00024419,
  "blocks": 2
}

# 矿工费和找零金额

那么最终的矿工费就是

>>> 442 * 0.00024419 / 1000
0.00010793198

1
2

为了演示方便，这里就取个整: 0.0001

所以找零金额为

>>> (0.00089454 + 0.00000546) - (0.00000546 + 0.00000546) - 0.0001
0.00078908
