Title: Metamask: MetaMask – RPC Error: execution reverted, Simple NFT Mintinging Dapp
Introduction*
As a developer building a systemple no-fungible token (NFT) minting for fundraising, I’ve encountered an unexploy issuit. In this article, I’ll outline the steps I too to troubleshoot and resolve oth Polygon testnet and Ethereum testnet.
The Problem
While integrating my fox wth my smart contractions, using MetaMask as a RPC clinic, I encuntered an unexped error. The issue was causing an “execution of reverted” error, it that the consion of the contraction’s had to the inner. stency or condition not met.
The Solution
To resolve this issue, I foirst revised my code and contraction for any potential errors or inconsistents that cold be contribuling. After reviewing my code, I realized that theee the small mistake in my constractor setup. Specifically, I have a set up up a simple mining function in on my contractions that was supposed to supposed to NFT.
To fix this issue, I modacti’s mining to return the minted NFT instead of instaem, to to iktly. This Change allowed me to resolve
Here is a it high-level example of the modified code:
contracts Mining {
// ...
Function mine() проблик nonReentrant {
// Mint NFT
mintNFT();
}
Function mintNFT() internal returns (address) {
// Return NFT tor
}
}
Deployment and Integration
With the issue resolved, I deployed both contractions on Polygon testnet and Ethereum. On testnet, I use MetaMask as a RPC click cliient to interact with my smart contractors.
Here’s an example of house I integrateed my front-end whe smart contractions using MetaMask:
`javascript
import { Deployer } from 'eters';
import * as web3 from 'web3';
const deployer = new Deployer();
const network = deployer.getChainByNumber(2); // 2 represents Ethereum testnet
// Deploy contact on Polygon testnet
deployer.deploy(Mining).then((address) => {
console.log(address);
});
// Deploy contact on Ethereum testnet
network.connect('goerli').deployer.deploy(Mining).then((address) => {
console.log(address);
});
`
Conclusion*
In this article, I demonstrated how an unexpected "RPC Error: reverted" error, that occurred itacting iticacting wthic contacts on and Ethereum testnet. By modifying themining` function inone of my contractions and using MetaMask as a RPC clieent, were to successful the dapp. This experience it imports of double-checking code and contract for errors that can be not be bear immediate apparent.
I hope that article helps from who are building similar projects!
