错误发生:EVM已恢复事务：

Question

Intro

我正在签第一份明智的合同。所以请放我一马。基本上，我正在尝试订立一个押注合同，其中我希望能够存放我的USDC，这应该通过使用我在合同中定义的stakeTokens()函数来完成。

我成功地使用松露在雪崩富士测试网上部署了我的合同。

目标

我试图使用合同中定义的stakeTokens(2，_from，_to)函数，从我的0x69e6E27BBA76B8789dB1E0AA0B816bF93570EFdf钱包中发送2个USDC到我的合同0x0B4ae929F3181815bA8Bd9873ED31b4e75e21aFE。更多信息，我有1.9 AVAX和7 USDC都在我的钱包测试网。

误差

现在，当我试图与智能契约交互时，我犯了以下错误：

你把to:字段忘在这里了。

因此，您的审批事务试图创建契约，但失败了。
