Metamask: Can’t figure out how I should optimize gas because it keeps saying gas fees are too high and they will probably go out of business. How can I fix this?

Understanding the Metamask Problem: Gas and Fee Optimization

As a user of the popular blockchain platform Metamask, you may be struggling with gas and fee optimization. In this article, we’ll dive deeper into the issue and provide steps to resolve it.

The Problem: High Gas Fees and Potential Failure

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

The Problem: Not Enough Gas

When you use Metamask to interact with a blockchain, it requires gas to perform smart contract execution. 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 the solutions, it is 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: Make sure there is enough 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:

۱. Check your gas 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 value
vrfConsumerBaseV2Plus(vrfTokenAddress).call(gasLimit * 10 ether, msg.sender);
// Update the Ether balance in the contract mapping
etherBalance[msg.sender] += gasLimit;
}
}

۲. Ensure Sufficient Funds

Make sure there is enough Ether (ETH) balance in your Metamask account to cover the 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 enough Ether balance
require(etherBalance[msg.sender] >= 0.۱ 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);
}
}

۳. Check network fees

Make sure the blockchain network fees are reasonable:
