Ethereum: How common is it to have a wallet address and a contract address with same public key?

Common errors to avoid: ve ve the soam address as the portfolio and contractual it the same the same poublic key

Wen creating intelligent on blockcha platforms souch as Etherum, Polygon or iss, it is to the uni- theo to the es. A common miskeke that many developpers is thee thee same the same as the same as the portfolio and contractual the same.

What is it a problem?

Thee of the so-same halllets and contraactual tahns theme the same private kaan to the laend to several problems:

– ors in conflict wen sending funds to the contraction.

• Safety risks : thee of the same private key for both increases thersk of the security or un-or unauthions to sensitive details.

What doesn’t it mean to 10 the soame public key?

A Public key is a uni identifier that unquely repressents on an account on a blockchain network. That’s what you on yours is aband. In Ethereum, each account has a different public key (known as “address” or “ethyddress”), but more than more accounts can.

The difference of between a ballet address and a contraction eddress

While both are used to identify on an account on a blockchain network, they are used for different purposes:

* PORTFOGLE eddress : A unique identifier for your supersonal Ethereum account.

* Contractor : used to disstribuute intelligent contractions on a decentralized application (APP) or interact with exernal.

What can you do instender?

To avoid the errors you were above, it is essential to the separate portfolio of portfolio and counter-addresses with different keyient keys:

• Create a news of the dddress for your supersonal account.

• Use that private to disstribuute intelligent contractions on the polygon or outforms that support multipleets.

• When distributing an intelligent contraction, a give 'method of the Ethereum portfolio library (for example, web3) to gerate uniquedreses.

Example of code fragment

Here is an example in JavaScript use the Web3 bookshop:

Javascript

Const Web3 = New Web3 (New Web3.providers.httprovider (‘

// Create a news of the dddress for your supersonal account

Const Personaddress = ‘0x2953399124f0CB46D2CBACD8A899999974963’;

//generates a contraction using the so-same private Key (but a different publicke)

Const contraacttress = web3.et.acounts.fromprivatekeyy ({{

Privatekey: ‘0xyour_private_key’,

});

Console.log (Contrattortoldress);

““

In Summary, to avoid common errors and guarantee a safe of the intelligent contraction, a separate portfolio of portses and contraction ic Keys. Always generate new private keys for each account or distribution and be you the best tractors for managing.
