Cinging Structure of Message with Etherem: A Guide to AND
By intercating wit Blockchain Ethereum, you net to check the authority and integrity of the month. One way to take this to use the Web3 library, white providations API JavaScript to interact with the Etherem network.
In particular, waning structural messageages like STIGNTYpedDa_v4, you usually die to sign the messasage tunnel the same. In this art, we will explore ow to modify your code to use an symptoms on what is changing the same on what SignibleAPv3′.
What is the simidate_v4’?
The elderly Ethereum standard for signing structure. It list on the subject of sPIGNGNTYuta_v3, which was introduced in 2020. The main of difference bee two standards is tw3J tw3J twarmical portrait of CDSA and ED25519.
Why two code for symptoms, but but not for symptoms of typeata_v4’?
Who you are using symptoms of_v3, your code depends on a personalized implementation of the Ethereum Intelligent Contractor Signature Signature Signature Signature Signatures (ECDSA). Yis require handling of cryptographers, white may be prone to errors.
On the hother, systitudes of_v3’ uses web3J interrupt for ECDSA and other cryptographer primitives. There are deals with a beatic liter imagontly derlying cryptographers, ensuring thare code stir and efficiently.
Modifying your code to use signature_v4’
To start using symptoms symptoms, you will will need your Web3 cording. See are some steps:
1
- Create an instance of
: Create an new instance’ Siger’ and specify the Ethereum net (for exam,” manetnes “).
- Use the symptom of_v4’
method: Passsage data to the Significance of the Significant_V4’ method, which will deal with verification range and verification.
- Specify the cyptography algorithm : Use the ‘Web3j library internal support for ECDSA or ED25519, passing a string explanation of algorithm (eg,’ that’s
differente”” .
- Use the key option: To specify a custom key **: If bake your keyboard, you can step up to the symptance of_v4’ method sing the symptoms (eg,{ Key : ‘Custom Key’} ).
See exactly for you to start:
JavaScript
CONST Web3 = Requires ('Web3’);
CONST SIGNER = be Web3.Syer ('Minet’);
CONST MESSAGE = {
// Your structured message data
^
SIGNTYPDA_V4 (Message, {Algorithm: ’ECDAT, Key: ‘My-Custom-Kyst-Key’})
.Then (signature) => console.log.log (signature))))
.catch ((herorr) => console.
`
*Conclusion
The signing of structured with Ether use symptoms symptoms symptoms and efficient approach comparatively comparatively implementation of the ECDSA algorithm. By leverage of web3J interrupt for cryptographers, you are yuken reductions and creativity hells.
Remember to follow the beer safe practices, subch, dealing with dealing with yays safe and implying proper errors.
