我正在尝试按照我在此处找到的内容从 bitcoinjs-lib 签署 Psbt 交易：

https://github.com/helperbit/helperbit-wallet/blob/master/app/components/dashboard.wallet/bitcoin.service/ledger.ts

我已经检查过来自分类帐的压缩公钥和来自 bitcoinjsLib 的压缩公钥返回相同的值。

我可以使用 bitcoinjs-lib ECPair 对其进行签名，但是当我尝试使用分类帐对其进行签名时，它总是无效的。

有人可以帮我指出我在哪里犯了错误吗？

这些变量已经在下面的代码中提到过，但为了清楚起见：

abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about

- previousTx:

这是我拥有的最少可重现代码。

鉴于一堂课,

class MyClass
  def index(arg1, arg2="hello")
  end
end

是否可以arg2通过某些方法获取默认值Class#instance_method？
