Programming of Ethereum’s address: Simple Wizard
When working with a blockchain ethereum, it may be decisive for various applications to have access to the user of the user. In this article,
** Why is this needed?
Interaction or services of third parties that transmit to Ethereum. This may include:
- Web3 -based applications (eg DAPPS)
- Metamask integration
- Apisation that participates
The best procedures: Use web3.js and the method “Et.Sendtransaction
Web3.JS, popular library for interaction with blockchain ethereum. Specifically, theet.sendtransaction ‘method is the best practice to get the user’s Ethereum address.
Here is an example of how to use it:
`Javascript
Const Web3 = Require (‘Web3’);
// Set your instance Web3
Const Web3 = New Web3 (New Web3.Providers.httpprovider (‘
// Get user Ethereum Ethr.Sendtransaction address
Async function Getuseraddress () {
Const transaction = acait web3.eth.gettransaction ({from: ‘your_user_address’});
return transaction.from;
}
Costautdress = expects Getuseraddress ();
Console.log (UseraddrDress); // output: your_user_address
`

Alternative options
While “Ethr.sendtransaction” is the most direct approach, you can encounter problems with:
* Cost and gas limits : The cost of the gas and the limit of your network can affect the result. Consider the use of a library such as @metamask/web3.js or ‘Ethereumjs-Wallet`, which provides greater flexibility in the management of costs and gas limits.
* API third parties

Conclusion
Programming Ethereum’s proven procedures and understanding with key food, you will be able to easily load the user’s Ethereum addresses and send them to API or third -party services as needed.
