Optimization of gas costs in Metask: Signing events with data with EIP 712
As a developer who works on Ethereum -based projects, you are probably not alien to gas management challenges. A significant assistant of significant gas taxes must send large amounts of data through the Ethereum transaction form. However, there is an alternative approach that can help reduce gases: signing at EIP 712.
In this article, we will take into account how to sign the event in Metask with EIP 712 and its advantages to optimize gas costs.
What is EIP 712?
EIP 712 (Ethereum Improvement 712) was the updated version of the Ethereum Standard Gas ID, which allows developers to define the types of personalized gases that can be used in several intelligent contracts. This feature allows a more efficient and scalable interaction between applications built in different chains.
EIP 712 setting in Metask
If you want to use the EIP 712 on your project, you must first place it in a Metask wallet. Here are the steps:
- Create or import the Ethereum account : Set a new Ethereum account in Metamas in or bring existing.
- Instalați pachetele necesare : Instalați pachetele
eether.jsșiWeb3folosind NPM sau thread:NPM Instalați Ethers@5 Web3
- Bring the EIP 712 Convention: Bring EIP 712 as a file, for example:
const {gastee} = insist ('Ether/types'); Bring 'https: //raw.githubusercontante.com/ethereum/eip-712/master/spec.json';
- Set the type of personalized gas : For example, specify the type of gas you want to use at the event:
Json
{
"Name": "Mycustomgasttepe",
"Description": "The type of personalized gas for my NFT project",
"Data": {
"Value": 100,
"Type": gastee.bytes32
}
}
Signing events with information with EIP 712
Now, when the type of personalized gas has been defined, it is time to sign the event using information instead of sending information normally. Here's an example:
Javascript
Async function setadditionalmetAdata (ntfcardadres) {
Const tx = {
Shipment: « Your Ethereum address »,
NONCE: Web3.eth.GettrasactTioncount (« Ethereum Address »),
Gasprice: Web3.Towei (20, ‘Gwei’), // Set the gas price 20 Gwei (2.5 ETH)
Gas: 2000,
Information: [
{
« Information »: [
{
« Type »: gasteepe.bytes32,
« Value »: New Uint8array ([1, 2, 3, 4])
},
{
« Type »: gasteepe.uint256,
« Value »: ‘1234567890ABCDEF’
}
–
}
],],
at: nftcardaddress
};
Const Signature = Wait Web3.etth.ccount.Signransction (TX);
Return {… tx, signed: signature.rawtrasction};
}
// sign data transaction in EIP 712
Const tx = setadditionalmetAdata (‘0xyournftcarddres’);
Const signnadtx = Wait Metask.Sendrasction (TX);
Console.log (signtx);
`
In this example, we define the new type of personalized gasMycustomgastepe and use it to sign the event with the data. Data contains two values: 4 whole syllables and 256 -bit entire businesses.
In signing EIP 712
events
Signing events with EIP 712 offers a number of benefits:
* Low gas costs : Since you do not send large amounts of information in the form of Ethereum, you can reduce the gas process.
* Improved Scarability : Using EIP 712 personalized gases, you can improve your application scalability.
* Increased flexibility : EIP 712 allows you to determine a wide range of personalized gases in different cases.
Conclusion
Signing events with EIP 712 is an effective way to optimize gas costs, while maintaining the benefits of using Ethereum -based applications.
