Setting the required gas fee to zero in Metamask on Localhost
As you embark on your solidity lesson, ensuring that the ETHEREUM gas transactions are set to be properly set into a decisive step. In this article, we will direct you by setting the required gas fee to zero using Localhost Metamask.
What is a gas fee?
Before you immerse yourself in the decision, it is essential to find out what gas fees are. Gas fees represent the cost of carrying out a transaction on the Ethereum blockchain. The higher the price of gas, the longer they need to process and verify transactions from nodes such as Mainnet or Local node operating with Metamask.
Why did the gas fee needed to zero?
In your solidity lesson, determining the required zero gas fee may seem contrasting at the beginning. However, there is a specific scenario where you would like to set it to zero:
- When using Localhost Local Node.js (Metamask).
- For certain types of transactions or intelligent contractual functions.
Method 1: setting the required gas fee to zero
To achieve this, follow these steps:
- Open your Metamask portfolio and open the
Settings tab .
- Click
transaction settings on the left menu.
- Scroll down to the
gas section .
- Select
set a gas limit .
- Enter a value for
gas limit , which is usually set to a minimum of 20,000 (0.020).
- For most cases, it is recommended to maintain this value at or below 10,000 (0.010). This will ensure that the required gas fee is zero.
Method 2: Using eth-accounts module
If you use the ETH-Acuts' module in your solidity contract, determining the required gas fee at zero may not be possible. In this case, you can use the following code fragment as a guide:
Solidness
Pragma Solidity ^0.8.0;
Contract MyContract {
UINT256 Public Balance;
Function Deposit () Public Pay {
Balance += Msg.Value;
// Set a gas limit using the ETH-Acuts' module (commented)
// Requires (msg.Value> 1, "insufficient funds");
// require (ouralsupply ()> = msg.Value, "the amount of the transaction exceeds total delivery");
}
}
In this example, the required gas fee is determined at zero, requiring at least 10 units of ether for the Function Deposit. Please note that setting the required gas fee to zero may not be possible for all cases of use.
Conclusion
Setting the required gas fee to zero in Localhost Metamask can be a useful optimization technique, especially when using a local node.js (Metamask) and some types of transactions or intelligent contract functions. Following these steps, you will be able to set the required gas fee to zero and ensure that transactions are further fired.
