合約轉賬/存入乙太幣失敗
我正在嘗試將乙太幣存入智能合約。查看文件，我的方法首先看起來像這樣：
// SPDX-License-Identifier: MIT pragma solidity ^0.0.8; contract SendEther { function deposit(uint256 amount) public payable { require(msg.value == amount); } }但是，失敗並顯示以下錯誤消息：

注意：如果您發送值並且您發送的值應該小於您目前的餘額，則呼叫的函式應該是應付的。
調試事務以獲取更多資訊。
然後我嘗試使用 transfer 或 call 方法發送 Ether。
// SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract SendEther { receive() external payable {} function sendViaTransfer(address payable to, uint256 amount) public payable { to.transfer(amount); } }這導致了這個錯誤：

嘗試使用“呼叫”或“發送”會導致相同的錯誤。
我究竟做錯了什麼？
日誌顯示消息值為 0。請確保在點擊功能之前在 remix 中設置 VALUE，以便發送值
首先，對於第一個範例，我認為您不需要
require(msg.value == amount).msg.value是發送到該合約的 eth 值。該amount參數在那裡沒有做太多。如果msg.value發送的與amount. 但無論如何，這樣做是多餘的。但是要確保如果你發送一個amount參數5，那麼你也應該發送5weis，這樣這個函式就不會失敗。function deposit(uint256 amount) public payable { require(msg.value == amount); }第二個例子看起來不錯。但是你的合約至少需要有
amountbalance 或者你應該發送一個與參數msg.value相同的 balance ( )amount。function sendViaTransfer(address payable to, uint256 amount) public payable { to.transfer(amount); }我用你可以接收和發送乙太的所有方式編寫了一些程式碼，並附上了一些評論，這可能對你有幫助。所有範例工作。請記住，在嘗試將乙太幣發送到另一個地址之前，乙太幣在您的合約中有足夠的餘額
SendEther，或者向該合約發送足夠的乙太幣，以便它可以使用msg.value並發送該金額。//SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract Receiver { receive() external payable {} fallback() external payable {} function receiveBalance() public payable {} function getBalance() public view returns(uint256) { return address(this).balance; } //..
