Title: Metamascus: Metamascus – Rpc Error: Execution Sell, Simple NFT MINING DAP
Introduction
As a programmer that constructs a simple not -bubble token (NFT) DAPP to raise funds, I have encountered an unexpected problem with my deployment. In this article, I will describe the steps I have taken to help and solve the « RPC Error Error: Revenue Execution » that occurred during interaction with my smart contracts on Polygon Testnet and Ethereum testnet.
Problem
While integrating my forehead into my smart contracts, using a metamask as a RPC client, I came across an unexpected mistake. The problem encountered me with an « executed » error, which meant that the execution of the contract function was canceled due to the internal inconsistency or unpaid state.
Solution
To solve this problem, I first examined my code and contracts for any potential mistake or inconsistencies that could contribute to the problem. After questioning my code, I realized that there was a small mistake in my configuration of the contract. More specifically, I set up a simple « mining » function in one of my contracts that was supposed to experience NFT.
In order to solve this problem, I changed the function of the « mining » of my contract to return the NFT created instead of trying to execute it directly. This change allowed me to solve the error « RPC Error: Execution was returned » and successfully implemented DAPP.
Here’s an example of a high -level modified code:
`Strength
Mining Agreement {{
// ...
Mine function () independence of the public {{
// NFT to mint
Mintnft ();
Iche
Mintnft () function of internal return (address) {{
// Return the NFT user
Iche
Iche
'
Introduction and Integration
The problem has been solved, I have arranged two contracts for the Polygon testnet and the Ethereum testnet. On the testnet, I used a metamask as a RPC client to interact with his smart contracts.
Here's an example of how I joined my front with smart contracts using metamask:
Javascript
Import {deployer} from 'ether';
Import * as a web3 from "Web3";
Const improviser = new improviser ();
Const Network = Depluyer.getchainbynumber (2); // 2 represents the Ethereum testnet
// Introducing a Treaty on Polygon Testnet
Depoyer.deploy (mining) .Then ((address) => {
Console.log (address);
});
// Introducing a contract on the Ethereum testnet
Network.connect ('Goerli'). Depluyer.Deploy (mining) .Then ((address) => {
Console.log (address);
});

Conclusion
In this article, I showed how to solve an unexpected error « RPC Error: Execution was » wrong « that occurred during interaction with my intelligent contracts on the Polygon Test and Ethereum testnet. By changing the function » Mining « in one of my contracts and using metamascus as RPC Client, we were able to successfully implement DAPP.
