RPC error 32603 by arranging a new ERC20

Agreement

I am sorry to hear that when you arrange a new ERC20 contract using Web3, you are faced with an error in the RPC (remote procedure). In this article, we will go into what the mistake is, why this is happening and how to solve it.

Information on error

The 32603 Error Code is an error that calls for a remote procedure, stating that there is a problem with the RPC protocol used in the Web3. In particular, the implementation of the contract fails due to problems with the ERC20contract with Openzeppelin.



Here are some key details of the error:


Error code: 32603

Name of Agreement:ERC20




Reason: "ERC20: RPC Failed"


 Why is this happening? 

The question here lies in the way web3 and Openzeppelin interpret each other. When implementing a new ERC20 contract, the Web3 uses the RPC protocol to call this contract method. However, Openzeppelin 'ERC20.Sol' contract has special requirements for calling it.

 problem solving

To solve this problem, you must be convinced that the implementation of the contract is correct and compatible with OpenzeppelinERC20. Here are some steps to help you:





۱. Check the implementation of the contract

Make sure the implementation of your contract is correct and adheres to all the rules set out in the ERC20 standard.



۲. Update Openzeppelin ERC20 contract

Update the "ERC20 SOL" file to meet the new ERC20 contract requirements you want to use.

power

Pragma Solidity ^0.8.14;

Import “@Openzeppelin/Agreement/Marker/ERC20/ERC20 SOL”;

// Define a new marker with custom implementation

// New Agreement implementing ERC20 and using Openzeppelin’s ERC20

Custom contract is ERC20 {

// Put your marker logic here …

Function _Beforemint () Inner viaduct {

super._beforemint ();

// Your customized peppermint logic …

ICE

Function _Beforburn () Internal Transfer {

Super._beforburn ();

// Your customized combustion logic …

ICE

۳. Check the contract implementation procedure

After updating the contract, make sure it is properly arranged using Web3.

`power

// distract from Web3 and ERC20 Library Agreement with Openzeppelin

Introduce “@web3 solidity (4.11.0)”);

Import “ERC20 SOL”;

Contract constipation {

// Your custom logic …

The main () Public Payment Function

// Your custom main logic …

ICE

After these steps, you should be able to solve the RPC error of 32603 by arranging a new ERC20 contract using Web3. Remember that you always carefully check your contracts before you arrange them in a manufacturing environment.

If you still have problems or have additional questions about solving this error, be sure to ask and I will do my best to help you!
