Creation of deterministic addresses Ethereum without Create2
In solidity, the creation of a deterministic address (i.e. a single) is crucial to face the keys and private accounts. However, the “Create2” function in the truffle is an alternative way to create addresses, especially when you do not intend to implement new contracts. In this article, we will examine how to create Ethereum deterministic addresses without the use of “Cre2”.
Understanding of deterministic addresses
In solidity, the deterministic address is one that always produces the same result, taking into account the same input (private key). This guarantees that users can trust their private keys and reduce the risk of compromise of the account.
Create functionality
The "Create2" function in the truffle allows you to create addresses with a fixed set of prefixes, such as 0x, 0xa or 0xb. However, when usingCreate2, you are limited to the available prefixes and it is not possible to generate non -standard combinations of prefixes.
Creation of deterministic addresses without Create2
To create deterministic addresses withoutCreate2 ‘, it is necessary to use a different approach. One of the solutions is the use of a library such as “Ethers-Polishfill-Aaktoouns” or “Tarche -Ters”. These libraries provide how to work with Ethereum accounts and generate personalized prefixes.
Here is an example of how it is possible to create a deterministic address without the use of “create2”:
Install the required library
Install the requested library first:
`Bash
NPM Instalne Ethers-Polishfill-Comice
Create a non -standard address
Create a new reliability file (eg "administration.sol) and add the following code:
`Solidity
Pragma solidity ^0.8.0;
Import "
Personalized contract {
Function created by
// generates a random number to ensure uniqueness
Uint256 Casual = Uint256 (Keccak256 (abi.encodepacked (block.timestamp)));
// Create a personalized prefix
Address Newprefix = 0x ...; // Replace the desired prefix
// returns the generated address
Return Kecak256 (abi.encodepacked (NewPrefix, casual));
}
}
Use a non -standard address
Now you can call the "CreateSteministicAddress" function to generate a personalized decisive address:
Solidity
Customaddress Memory Address = Customaddress;
Addaddress = address.coreTetedetermereministicaDdress ();
In this example, we define a non -standard contract called "customaddress". The "CreateEdeteristicAddress" function generates a random number and uses it as a wheat for non -standard prefix. This guarantees that all the addresses generated are unique.
Application
When using "Cre2", it can simplify its workflow in some cases, there are scenarios in which the creation of deterministic addresses is necessary without it. Following this guide, you learned to create non -standard deterministic addresses in solidity without relying on the "Crea2" function. Remember to choose a library as` Ethers-Polishfill-Counts’ or “Truffle-Esteri” to work with Ethereum accounts and generate a non-standard prefix.
