您好，我正在尝试使用 Polygon 铸造一个 NFT，它在孟买运行得很好，但是一旦我切换到主网，交易就不会通过，而是在 5 秒内通过孟买。即使我使用的是刚刚部署在主网上而不是孟买的完全相同的合约，并且代码也是相同的。我所做的只是切换合约地址和 rpc url，但由于某种原因，它在 Polygon 主网上不起作用，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);
也试过这个签名
// 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,
);

主网上使用 30 gwei 的气体：
有人知道为什么会这样吗？另外，是的，我确实知道快速的气体确实有 2 个额外的 gwei，但即使手动设置它仍然需要很长时间，根据https://polygonscan.com/gastracker，即使有 1 个 gwei，它也应该在 30 秒内处理. 即使使用 50 Gwei，它似乎也需要几个小时来处理，或者它可能被丢弃了？交易似乎甚至没有进入合同，它们只是卡在链中的某个地方。合约地址：0xa915E82285e6F82eD10b0579511F48fD716a2043
