RPC Error 32603 when deploying new ERC20 contracts
We are sorry to hear that you are experiencing an error while deploying new ERC20 contracts via Web3. In this article, we will go over what the error means, why it occurs, and how to fix it.
Error Details
Error code 32603 is a remote procedure call error that indicates that there is a problem with the RPC protocol used by Web3. Specifically, the contract deployment process is failing due to an issue with the OpenZeppelin “erc20” contract.
Here is some basic error information:
- Error Code: 32603
- Contract Name: “ERC20”.
- Reason: “ERC20: RPC Failed”
Why is this happening?
The issue is with how Web3 and OpenZeppelin interact. When you implement a new ERC20 contract, Web3 uses the RPC protocol to call the methods of that contract. However, the OpenZeppelin ERC20.sol contract has specific requirements for how it should be called.
Troubleshooting
To resolve this issue, you need to make sure that your contract implementation is correct and compatible with the OpenZeppelin ERC20 contract. Here are some steps to help you:
1. Check your contract implementation
Make sure that your contract implementation is fair and follows all the rules set out in the ERC20 standard.
2. Update the OpenZeppelin ERC20 contract
Update the erc20.sol file in OpenZeppelin to match the requirements of the new ERC20 contract you want to use.
`robustness
pragma robustness ^0.8.14;
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
// Define a new token with a custom implementation
// A new contract that implements ERC20 and uses ERC20 from OpenZeppelin
The "CustomToken" contract is ERC20 {
// Implement your token logic here...
function _beforeMint() inner override {
super._beforeMint();
// Your logic is applied...
}
function _beforeBurn() inner override {
super._beforeBurn();
// Custom burn logic...
}
}
`solidity3. Verify the contract implementation process
After updating the contract, verify that it is implemented correctly using Web3.
// Import the Web3 library and ERC20 contract from OpenZeppelin
import "@web3 solidity (4.11.0)");
import "erc20.sol";
contract CustomToken {
// Your logic is custom...
function main() public public {
// Your logic is custom main...
}
}
Following these steps should resolve the RPC error 32603 when deploying new ERC20 contracts via Web3. Remember to always test your contracts thoroughly before deploying them in production.
