区块燃气管理指南

// 获取区块燃气限制
const getBlockGasLimit = async () => {
	const block = await web3.eth.getBlock('latest');
	return block.gasLimit;
};

// 估算最佳燃气价格
const getOptimalGasPrice = async () => {
	const blockCount = 10;
	const latest = await web3.eth.getBlockNumber();
	const blocks = await Promise.all([...Array(blockCount)].map((_, i) => web3.eth.getBlock(latest - i)));

	const gasPrices = blocks.map((block) => block.baseFeePerGas);
	return Math.floor(gasPrices.reduce((a, b) => a + b) / blockCount);
};
