Creating Deterministic Ethereum addresses without Create2
In thoroughness, creating a deterministic (ie unique) address is crucial when dealing with private keys and accounts. However, in Truffel, the Create2 function provides an alternative way to create addresses, especially when you do not intend to introduce new contracts. In this article, we will look at how to create deterministic Ethereum addresses without using Create2.
Understanding of deterministic addresses
In firmness, the deterministic address that always produces is the same departure because of the same income (private key). This ensures that users can rely on their private keys and reduce the risk of accounting.
Luo2functionality
In the truffle, "Luo2, lets you create addresses with a fixed prefix, such as 0x, 0xa or 0xb. When using theCreate2, you are limited to available prefixes and cannot create customized prefix combinations.
Creating Deterministic addresses without Luo2
In order to create deterministic addresses without “Luo2”, you need to use a different approach. One solution is to use a library, such as the ‘ether polyfill accounts’ or ‘truffle ethics’. These libraries offer a way to work on Ethereum accounts and create customized prefixes.
Here is an example of how you can create a deterministic address without using create2 ::
Install the required library
First install the required library:
`Bash
NPM Install Ethers-Polyfill Accounts
Create a custom address function
Create a new solid file (eg “address function.sol) and add the following code:
Severity
Pragman solidity ^0.8.0;
Import " contracts/src/v4/abstraccteumtoken.sol";
Convention CustomAddress {
Function ConetterMinistDDRESS () Public return (address) {
// creates a random number to ensure uniqueness
UINT256 Occasional = UINT256 (KECCAK256 (abi.codepacked (block.itimestamp)));
// Create a custom prefix
Address NewPrefix = 0x ...; // Replace the prefix you want
// Return the address created
Return Keccak256 (abi.enencodepacked (NewPrefix, random));
}
}
Use custom address function
Now you can call the Conetterministdress function to create a customized deterministic address:
`Severity
CustomAddress address = CustomAddress (address function);
AddressDdress = Address.CreatederministAstress ();
In this example, we define a custom agreement called ‘CustomAddress’. The “conetterministdress” function produces a random number and uses it as a seed for a custom prefix. This ensures that all addresses created are unique.
conclusion
Although the Creat2 use can simplify the workflow in some cases, there are scenarios in which the creation of deterministic addresses without it is necessary. By following this guide, you have learned how to create customterministic addresses with a steady relying on the Create2 function. Remember to choose a library such as `Ether Polyfill Accounts ‘or Tryffel Eters’ to work on Ethereum accounts and create custom prefixes.
