示例代码

首先获取锚定地址：

~$ elements-cli getpeginaddress
{
  "mainchain_address": "2ND8PB9RrfCaAcjfjP1Y6nAgFd9zWHYX4DN",
  "sidechain_address": "2dhKcR3YFm2kwRQtqtvwbpdpeuXcTv4JJyh"
}

然后在主链向锚定地址充值：

~$ bitcoin-cli sendtoaddress 2ND8PB9RrfCaAcjfjP1Y6nAgFd9zWHYX4DN 10.0

获取主链交易的序列化表示：

~$ bitcoin-cli getrawtransaction f7c750007586f68c6d0b1a85680ef5662561612b9497128d8a8913e9587878b4
