Create a custom address function
Create a new Solidity file (e.g. addressFunction.sol
) and add the following code:
pragma solidity ^0.8.0;
import "
contract CustomAddress {
function createDeterministicAddress() public returns (address) {
// Generate a random number to ensure uniqueness
uint256 random = uint256(keccak256(abi.encodePacked(block.timestamp)));
// Create a custom prefix
address newPrefix = 0x...; // Replace with the desired prefix
// Return the generated address
return keccak256(abi.encodePacked(newPrefix, random));
}
}
Use the custom address function
Now you can call the createDeterministicAddress
function to generate a custom deterministic address:
CustomAddress memory address = CustomAddress(addressFunction);
addressAddress = address.createDeterministicAddress();
In this example, we define a custom contract called `CustomAddress'. The
createDeterministicAddressfunction generates a random number and uses it as the starting point for a custom prefix. This ensures that all generated addresses will be unique.
Conclusion
While usingcreate2can simplify your workflow in some cases, there are scenarios where creating deterministic addresses without it is necessary. By following this guide, you have learned how to create custom deterministic addresses in Solidity without relying on the
create2function. Be sure to choose a library like
ethers-polyfill-accountsor
truffle-ethers` to work with Ethereum accounts and generate custom prefixes.
