Title: Metask: Metask – RPC Error: Execution is sold, DAP Simple NFT MINING
Introduction
As a developer who builds a simple non -bubble (NFT) DAPP to raise funds, I have encountered an unexpected problem with my implementation. In this article, I will describe the steps I have taken to help and solve the error “RPC error: income execution” that took place during interaction with my smart contracts on Polygon Teston and Ethereum Testin.
problem
While I integrated my forehead into my smart contracts, using Metask as a RPC customer, I met an unexpected error. The problem made me encounter an error “executed by execution”, which meant that the execution of the contract functions was canceled due to an internal inconsistency or an unpaid condition.
Solution
To solve this problem, I first examined my code and contracts for any potential error or inconsistencies that could contribute to the problem. After examining my code, I realized that there is a small error in the configuration of my contract. Specifically, I set up a simple “mining” function in a contracts, which had to experience an NFT.
To solve this problem, I changed the “mini” function 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: the execution was returned” and has successfully implemented DAPP.
Here is a high -level example of the modified code:
`Solidity
Mining contract {
// ...
Me function () public us -resenting {
// nft to mint
Mintnft ();
}
Mintnft () Internal return (address) function {
// returns NFT to the user
}
}
”
unfolding and integration
The problem solved, we implemented the two contracts on Poligon Testnet and Ethereum Testnet. On the test, I used Metask as a RPC customer to interact with my smart contracts.
Here is an example of how I joined the front-end with smart contracts using Metask:
`JavaScript
Import {imployer} from "Ethers";
Import * as web3 from "Web3";
Consist implyer = new deployer ();
Const Network = Implui.Getchainbynumber (2); // 2 represents Ethereum Testnet
// Implementation of the contract on Polygon Testnet
DEPOYER.PULY (MINING) .Then ((address) => {
console.log (address);
});
// Implementation of contract on Ethereum Testnet
Network.connect ('Goerli'). FLUYER.PULY (MINING) .Sen ((address) => {
console.log (address);
});
”
Conclusion
In this article, I have shown how to solve an unexpected error “RPC error: the execution was” wrong “that took place during interaction with my intelligent contracts on Polygon Teston and Ethereum Testnet. By modifying the “minie” function in a contracts and using Metamk as a RPC customer, I could successfully implement DAPP.
I hope this article helps others to build similar projects!
