多边形事务在孟买上运行良好，但在主网上运行不佳 [英] Polygon transaction working just fine on Mumbai but not on Mainnet

问题描述
你好，我正在尝试使用Polygon创建一个NFT，它在孟买运行得很好，但一旦我切换到主网，交易就不会进行，而是在孟买在5秒内完成。尽管我使用的是完全相同的合同，只是部署在主机上，而不是孟买，代码也是相同的。我所做的只是切换合同地址和RPC URL，但由于某种原因，它在Polygon Mainnet上不起作用。下面是我使用的代码。
// Init contract
const contractABI = require('../../contract-abi.json');
const contractAddress = config.mintingContractAddress;
const contract = await new this.web3.eth.Contract(contractABI, contractAddress);
// Mint NFT
const nft = contract.methods.mintNFT(user.walletAddress, metadataUploadURL, user.paymentAddress).encodeABI();
// Get gas pricing
const priorityFees = await axios.get('https://gasstation-mainnet.matic.network');
const estBaseGas = await this.web3.eth.estimateGas({
data: nft,
to: contractAddress,
});
console.log('USING GAS: ' + estBaseGas);
// Sign NFT minting transaction
const totalGas = estBaseGas + priorityFees.data.standard;
console.log('TOTALGAS: ', Math.round(totalGas).toString());
const transaction = await this.web3.eth.accounts.signTransaction(
{
from: user.walletAddress,
to: contractAddress,
nonce: await this.web3.eth.getTransactionCount(user.walletAddress, 'pending'), // Get count of all transactions sent to the contract from this address including pending ones
data: nft,
// maxPriorityFee: priorityFees.data.average, Not supported on Polygon MATIC yet
gas: Math.round(totalGas).toString(),
gasPrice: await this.web3.eth.getGasPrice(),
},
wallet.privateKey,
);
this.logger.silly('Finished signing NFT transaction');
// Send the transaction that we signed
const mintT = await this.web3.eth.sendSignedTransaction(transaction.rawTransaction);
this.logger.silly('Sent transaction');
console.log(mintT);
我还尝试了此签名
// Get gas pricing
const priorityFees = await axios.get('https://gasstation-mainnet.matic.network');
const estBaseGas = await this.web3.eth.estimateGas({
data: nft,
to: contractAddress,
});
console.log('USING GAS: ' + estBaseGas);
// Sign NFT minting transaction
const totalGas = estBaseGas + priorityFees.data.standard;
console.log('TOTALGAS: ', Math.round(totalGas).toString());
console.log('P', priorityFees.data.standard);
const gp = this.web3.utils.toWei(priorityFees.data.standard.toString(), 'Gwei').toString();
console.log('GP', gp);
const transaction = await this.web3.eth.accounts.signTransaction(
{
from: user.walletAddress,
to: contractAddress,
nonce: await this.web3.eth.getTransactionCount(user.walletAddress, 'pending'), // Get count of all transactions sent to the contract from this address including pending ones
data: nft,
// maxPriorityFee: priorityFees.data.average, Not supported on Polygon MATIC yet
gas: '1000000',
gasPrice: gp,
},
wallet.privateKey,
);
Mempool Explorer for Transaction，耗时永远不变，几乎是瞬间完成。 永远： 即时： 主网上的一个使用了30吉瓦的天然气： 有人知道为什么会发生这种事吗？ 此外，是的，我知道快速的有两个额外的GWI的气体，但即使手动设置，它仍然需要永远，根据https://polygonscan.com/gastracker，即使有一个GWI，它应该在30秒内处理。即使使用50Gwei，似乎也要花几个小时才能处理，或者它可能正在被丢弃？交易似乎甚至没有达成合同，它们只是卡在了链条上的某个地方。 联系地址：0xa915E82285e6F82eD10b0579511F48fD716a2043

}
推荐答案
您可以使用简单的代码进行测试，只需生成一个NFT。将gas Price和gas Limit参数直接添加到minting函数可以帮助
const hre = require("hardhat");
async function main() {
const NFT = await hre.ethers.getContractFactory("NFTNAME");
const WALLET_ADDRESS = "0xxxxxxxxxxxxxx"
const CONTRACT_ADDRESS = "0xa915E82285e6F82eD10b0579511F48fD716a2043"
const contract = NFT.attach(CONTRACT_ADDRESS);
mintedNFT = await contract.mintNFT(WALLET_ADDRESS,{ gasLimit: 285000, gasPrice: ethers.utils.parseUnits('30', 'gwei')});
console.log("NFT minted:", mintedNFT);
}
main().then(() => process.exit(0)).catch(error => {
console.error(error);
process.exit(1);
});
