WEB3JS事务裁剪

Question

我想通过WEB3JS与我的智能合同进行交互。目前，我面临的问题是，在铸造令牌，它失败了。

块资源管理器上的示例：https://mumbai.polygonscan.com/tx/0x5c51ea9807abb2b99e20ca6905d4039f7f8f9ccd4c0945b17f0b4b1623273f5f

这是当前的代码：

        //Adding QuickNodeAPI
        var web3 = new Web3('https://restless-warmhearted-tent.matic-testnet.discover.quiknode.pro/XXXXXXXXX/%27);

        // Setting wallet variables
        const privateKey = 'XXXXXXX';
        var WalletID = '0xc7deAF4E3C5900a725c1d5D076859c9606395620';
        web3.eth.accounts.wallet.add(privateKey);

        // Use the web3 instance to create the contract instance
        const Contract = new web3.eth.Contract(, '')

        // Creating the transaction
        const tx = {
          gasLimit: 500000, // Use the minimum gas limit
          gasPrice: web3.utils.toWei('20', 'gwei'), // Set the gas price to 20 gwei
          nonce: web3.eth.getTransactionCount(WalletID),
          data: Contract.methods.mint('0xc7deAF4E3C5900a725c1d5D076859c9606395620', web3.utils.toWei('3', 'ether')).encodeABI(),
        };

        //Signing transaction and error handeling
        web3.eth.accounts.signTransaction(tx, privateKey).then(signed => {
          web3.eth.sendSignedTransaction(signed.rawTransaction).on('transactionHash', txHash => {
            web3.eth.getTransactionReceipt(txHash).then(receipt => {
              if (receipt) {
                console.log('Transaction confirmed')
              } else {
                console.log('Transaction pending')
              }
            });
          });
        }) 

非常感谢你抽出时间。

您需要将契约的地址(目的地)添加到您的事务中。

可能在这里

      const tx = {
          to: 'the-address-of-the-contract'
          gasLimit: 500000, // Use the minimum gas limit
          gasPrice: web3.utils.toWei('20', 'gwei'), // Set the gas price to 20 gwei
          nonce: web3.eth.getTransactionCount(WalletID),
          data: Contract.methods.mint('0xc7deAF4E3C5900a725c1d5D076859c9606395620', web3.utils.toWei('3', 'ether')).encodeABI(),
        };

如果没有正确的to，evm认为您正在尝试创建一个契约。你可以在多边形扫描仪上看到它写着“创建了合同0x022da72497c5e5f4476e6ca3123ae48a52a0e0”并失败了。
