Ethereum: Deploying contract through create2 is returning a zero address

Ethereum contract implementation questions: Create2 returns the zero address
In the field of Ethereum’s intelligent contracts, the implementation and execution of functions is a crucial part of the construction of decentralized applications. A common problem that can arise when using the Create2 Implementation function is returning a zero address.
We recently found this problem when trying to implement our NFT implementation contract through the Create2 method. Our implementation was simple: an ERC721 contract has just executed, as well as another intelligent contract.
In this article, we will delve into the problems that led us to this problem and explore solutions to overcome them.
The problem: Create2 returns the zero address
When using Create2, the deployment function tries to create a new contract instance from the arguments provided. However, if a problem arises during the contract creation, such as an intelligent contract that is not being implemented correctly or an invalid memory layout, the Create2 function will return a zero address.
In our case, the point was that we were passing incorrect arguments to builder ERC721, which resulted in the corrupted layout of the memory of the contract. As a result, when Create2 tried to create the contract instance, he returned a zero address, leading to a reversal error.
Step problem solving
To solve this problem, follow these steps:
- Check contract arguments : Make sure you are passing the correct arguments to the ERC721 builder. In our case, we were losing a necessary argument.
- Use clearance tools : Use clearance tools such as truffle console or web3.js to inspect the memory layout of the contract instance and check your condition.
- Check intelligent contract deployment errors : Use smart contract deployment tools such as Truffle Suite or Hardhat to inspect the metadata of the implanted contract, such as your bytecode, source code and other relevant details.
Solutions
To overcome the issue of returning a zero address with Create2, try the following solutions:
Solution 1: Check the contract arguments
If you suspect that your contracted arguments are incorrect, check them the same arguments to the ERC721 builder. You can do this using the web3.js console or purifier of the Truffle.
`JavaScript
// in its ERC721 function
Consta nftimplementation = artefacts.require (“nftimplementation”);
Implant function () {
Consta nftimplementationddress = Wait nftimplementation.deplayed ();
// Check the contract arguments are correct
assert.equal (nftimplementationddress, “0x …”); // Replace with real value
Return nftimplementationddress;
}
`
Solution 2: Use debugging tools
If you are using truffles or web3.js to deploy and interact with contracts, use debugging tools such as the console or a caution. These tools can help you identify problems that may be causing Create2 to return a zero address.
Solution 3: Make sure there are intelligent contract implementation errors
Use intelligent contract implementation tools to inspect the metadata of the implanted contract, such as your bytecode, source code and other relevant details. Additional steps or settings may be required to solve any problems that lead to a reversal error.
Following these solutions and problem solving steps, you can solve the Create2 ‘problem return a zero address and successfully deploy your NFT implementation contract.
Example of case use
Here is an example of how you can modify your deployment script to include verification and clearance:
`JavaScript
Consta {ether} = requires (“ethers”);
asynchronous function deploy () {
to try {
Consta nftimplementationddress = Wait nftimplementation.deplayed ();
// Check contract arguments are correct
Assert.equal (nftimplementationddress, “0x …
