Kadena Pact创建账户失败求助：使用sender00密钥对创建账户报错

问题情况 #

我按照官方指引创建coin账户，调用getBalance("sender00")能正常获取余额，但使用sender00的密钥对创建新账户testaccount时操作失败。

正常的getBalance返回结果 #

问题原因与修复方案 #

报错提示找不到对应公钥的行，核心问题是交易meta中的sender字段填错了：Kadena要求sender填写的是账户名称（比如sender00），而不是账户对应的公钥。因为购买gas时需要从指定账户扣除余额，账户是通过名称而非公钥来识别的。

修改后的代码部分 #

需要将getBalance和createAccount函数中meta.sender的值改为账户名sender00：

修改getBalance函数的meta部分

meta: {
  creationTime: creationTime(),
  ttl: 28000,
  gasLimit: 600,
  chainId: CHAIN_ID,
  gasPrice: 0.0000001,
  sender: "sender00" // 替换为账户名，而非公钥
}

修改createAccount函数的meta部分

meta: {
  creationTime: creationTime(),
  ttl: 28000,
  gasLimit: 600,
  chainId: CHAIN_ID,
  gasPrice: 0.0000001,
  sender: "sender00" // 替换为账户名，而非公钥
}

修改后重新执行脚本，即可正常创建新账户。
