如何將 eth_estimateGas 用於 erc20 代幣？

  • September 10, 2020

我想計算 BNB、PAX、LINK 的估計氣體，我使用了 geth 1.8 和 web3.php

我使用的契約數據（我從 etherscan 找到的）：

<?php
   /**
    * @var array
    */
   public static array $PAX = [
       'abi' => '[{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"assetProtectionRole","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"decimals","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"paused","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"symbol","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"betaDelegateWhitelister","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"proposedOwner","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"EIP712_DOMAIN_HASH","outputs":[{"name":"","type":"bytes32"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"supplyController","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":true,"name":"to","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Transfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"owner","type":"address"},{"indexed":true,"name":"spender","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Approval","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"currentOwner","type":"address"},{"indexed":true,"name":"proposedOwner","type":"address"}],"name":"OwnershipTransferProposed","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"oldProposedOwner","type":"address"}],"name":"OwnershipTransferDisregarded","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"oldOwner","type":"address"},{"indexed":true,"name":"newOwner","type":"address"}],"name":"OwnershipTransferred","type":"event"},{"anonymous":false,"inputs":[],"name":"Pause","type":"event"},{"anonymous":false,"inputs":[],"name":"Unpause","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"addr","type":"address"}],"name":"AddressFrozen","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"addr","type":"address"}],"name":"AddressUnfrozen","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"addr","type":"address"}],"name":"FrozenAddressWiped","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"oldAssetProtectionRole","type":"address"},{"indexed":true,"name":"newAssetProtectionRole","type":"address"}],"name":"AssetProtectionRoleSet","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"to","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"SupplyIncreased","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"SupplyDecreased","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"oldSupplyController","type":"address"},{"indexed":true,"name":"newSupplyController","type":"address"}],"name":"SupplyControllerSet","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":true,"name":"to","type":"address"},{"indexed":false,"name":"value","type":"uint256"},{"indexed":false,"name":"seq","type":"uint256"},{"indexed":false,"name":"fee","type":"uint256"}],"name":"BetaDelegatedTransfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"oldWhitelister","type":"address"},{"indexed":true,"name":"newWhitelister","type":"address"}],"name":"BetaDelegateWhitelisterSet","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"newDelegate","type":"address"}],"name":"BetaDelegateWhitelisted","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"oldDelegate","type":"address"}],"name":"BetaDelegateUnwhitelisted","type":"event"},{"constant":false,"inputs":[],"name":"initialize","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[],"name":"initializeDomainSeparator","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs

我能做些什麼？

from如果帳戶沒有令牌，估計將不起作用，因為呼叫會失敗。您需要將您要購買的代幣estimateGas放入from地址中，或者使用已經有代幣作為from地址的錢包
