Ethereum’s implementation issues: Luo2
Restore zero address
In the Kingdom of Intelligent Smart Agreements, the introduction and implementation of operations is an important part of the construction of decentralized applications. One common problem that can arise when using the Create2
utilization function is the restoration of the zero address.
Recently, we met this problem in trying to enable our NFT implementation agreement using the “Luoli2” method. Our implementation was simple: it just implemented the ERC721 agreement in addition to another intelligent agreement.
In this article, we deepen the questions that led us to this problem and explore solutions to overcome them.
Problem: Luo2
returns the zero address
When you use the Create2
, the deployment feature tries to create a new contract atmosphere from the supplied arguments. However, if there is a question, such as an intelligent contract that is not used properly or incorrect memory setting, “Luoli2function returns the zero address.
In our case, the question was that we conveyed the wrong claims to the ERC721 builder, which led to the damage to the memory setting. As a result, when "Luoli2 tried to create a contract, it returned the zero address, which led to a return error.
troubleshooting stages
The troubleshooting of this problem follows these steps:
- Confirm the contract arguments : Double-accurate that you pass the right arguments to the ERC721 builder. In our case, we lacked the required “Count” argument.
- Use error correction tools : Use error correction tools such as truffle console or web3.js error correction
- Check intelligent contract deployment errors : Use intelligent contract deployment tools, such as a truffle package or hardhat, to check the metadata of the contract, such as its syllable code, source code and other relevant details.
Solutions
Try the following solutions to solve the reset of zero address with Create2
:
Solution 1: Ensure contract arguments
If you suspect that the contract arguments are incorrect, check them by transferring the same arguments to the ERC721 builder. You can do this with Tryffle console or web3.js debugger.
`Javascript
// in ERC721
Const nftimplementation = Artifacts.require (“nftimplementation”);
Function to use () {
Const nfttimplementationaddress = Wait nftimplementation.Deployed ();
// make sure that contract arguments are correct
assert.equal (nfttimplementationaddress, “0x …”); // replace with real value
Return to nfttimplementationaddress;
}
`
Solution 2: Use error correction tools
If you use truffle or web3.js to enable and interact with contracts, use error correction tools such as a console or error correction. These tools can help you identify problems that may cause the Create2 to return the zero address.
Solution 3: Check intelligent contracts to set up the intelligent contracts
Use intelligent contract deployment tools to check the metadata of the contract implemented, such as its byte code, source code and other relevant details. You may need to perform additional steps or configurations to solve the problems that lead to a return error.
By following these solutions and stages of failure, you should be able to resolve the "Luo2" question to return the zero address and successfully NFT implementation agreement.
Example of use
Here's an example of how to edit your deployment command series to include certification and error correction:
Javascript
Const {etheres} = demand (“ethers”);
ASYNC FUNCTION OFFER () {
Try {
Const nfttimplementationaddress = Wait nftimplementation.Deployed ();
// make sure that contract arguments are correct
assert.equal (nfttimplementationaddress, “0x …
