Understanding the Metamask Issue: Gas Optimization and Fees

As a user of the popular blockchain platform Metamask, you may be experiencing difficulties with gas optimization and fees. In this article, we will delve into the issue and provide steps to resolve it.

The Problem: High Gas Fees and Potential Failure

Metamask is an open-source browser-based wallet that allows users to interact with various Ethereum-compatible blockchains. However, one of its core features is the ability to execute smart contracts on these chains using the VRF (Virtual Random Function) decentralized random number generator. This feature relies heavily on gas optimization to ensure that the transaction is executed efficiently and reliably.

The Issue: Insufficient Gas

When you use Metamask to interact with a blockchain, it requires gas to execute the execution of smart contracts. However, if the gas fee is too high, it can lead to several issues:

  • Transaction failure: If the gas fee is too low, the transaction may fail or be rejected by the blockchain.

  • Slowness: A high gas fee can result in slow processing times for your transactions.

  • Increased risk of errors: High gas fees can also increase the likelihood of errors and rejections during the transaction process.

Possible Causes:

Before diving into solutions, it’s essential to identify the possible causes of the issue:

  • Incorrect gas settings: Make sure you have set the correct gas limit for your transaction.

  • Insufficient funds: Ensure that there is sufficient Ether (ETH) balance in your Metamask account to cover the gas costs.

  • High network fees: The gas fee on the blockchain can be high, especially when executing complex transactions.

Solutions:

To resolve the issue, follow these steps:

1. Check Throttle Settings

Make sure you have set the correct gas limit for your transaction:

pragma solidity ^0.8.20;




import "./Errors.sol";


import "@openzeppelin/contracts/token/ERC20/IERC20.sol";


import "@chainlink/contracts/src/v0.8/vrf/dev/VRFConsumerBaseV2Plus....";


import "metamask-sdk.sol"




contract MySmartContract { {


    mapping ( uint256 => Ether ) public etherBalance ;


    


    function sendEther() public {


        // Set the correct gas limit


        uint256 gasLimit = 1000000; // Set a minimum of 1,000,000 gas units


        


        // Call the VRFConsumerBaseV2Plus contract with the specified gas and execution amount


        vrfConsumerBaseV2Plus(vrfTokenAddress).call(gasLimit * 10 ether, msg.sender);


        


        // Update the Ether balance in the contract's mapping


        etherBalance[msg.sender] += gasLimit;


    } }


} }

2. Ensure Sufficient Funds

Make sure you have enough Ether (ETH) balance in your Metamask account to cover your gas costs:

pragma solidity ^0.8.20;




import "./Errors.sol";


import "@openzeppelin/contracts/token/ERC20/IERC20.sol";


import "@chainlink/contracts/src/v0.8/vrf/dev/VRFConsumerBaseV2Plus....";


import "metamask-sdk.sol"




contract MySmartContract { {


    mapping ( uint256 => Ether ) public etherBalance ;


    


    function sendEther() public {


        // Check if there is sufficient Ether balance


        require (etherBalance [msg. sender] >= 0.1 ether, "Insufficient funds");


        


        // Set the correct gas limit and execute the transaction


        uint256 gasLimit = 1000000; // Set a minimum of 1,000,000 gas units


        vrfConsumerBaseV2Plus(vrfTokenAddress).call(gasLimit * 10 ether, msg.sender);


    } }


} }

3. Check Network Fees

Make sure that the blockchain network fees are reasonable:
