Metamask RPC Error: Execution Revoked – Next.js Function Call Troubleshooting Guide

As a Next.js developer, you are no stranger to dealing with complex API calls and asynchronous workflows. However, when it comes to interacting with decentralized applications (dApps) like MetaMask on the Ethereum blockchain, things can get a little more complicated. Specifically, you have encountered an error message that looks like this: “RPC Error: Execution Revoked”.

At first glance, this may seem like a simple issue related to contract addresses or ABI versions. However, before we jump to conclusions, let’s dive deeper into the events and explore possible solutions.

What is RPC Error: Execution Revoked?

In Ethereum blockchain transactions, the executionRevoked error occurs when the execution of an Ethereum transaction fails for some reason. This can be caused by a number of factors, including:

• Smart contract logic errors

• Transaction validation issues

• Interoperability issues with other blockchains

When a smart contract execution is canceled, it means that the blockchain rejected the transaction or function call due to an internal conflict or error.

Why might this error occur?

To better understand what is happening, let’s take a closer look at the code. Assuming you have configured your Next.js project with MetaMask integration, here are some possible causes:

• Contract address mismatch: If the contract address provided in the useMetaMask hook does not match the actual contract address used on the blockchain, it can result in a cancellation error.

• ABI Version Mismatch: Even if you are using the correct contract ABI, there may be a conflict between the ABI version required by MetaMask and the ABI version used by your code. Make sure you import the latest ABI versions from all relevant contracts.

• Smart Contract Logic Errors

  : Intentionally or unintentionally writing incorrect smart contract logic can cause execution cancellation errors.

Troubleshooting Steps:

To resolve this issue, follow these steps:

• Check contract addresses and ABIs: Double-check that your contract addresses are correct and that the ABI versions match both MetaMask and your requirements.

• Update Next.js code to match MetaMask’s contract address

  

  : Make sure your “useMetaMask” hook uses the correct contract address, even if it is different from the address you provided in your code.

• Check for smart contract logic errors: Review your code to make sure there are no syntax or logic errors that could cause execution rollback errors.

Example use cases:

Here is an example of how you can modify your “useMetaMask” hook to validate the contract address and ABI:

“` jsx

import { MetaMask } from “@metamask-connect”;

import { useContract } “next useContract”;

const Metamask = () => {

const { account, setAccount } = useMetaMask();

const executeSmartContract = async (contractName) => {

// Check contract address and ABI

if (!account || !account.abi || account.abi.length !== contractName.length) {

console.error(“Invalid contract name or ABI.”);

return;

}

try {

const result = await executeContract(account, contractName);

console.log(result);

} catch (error) {

console.error(error);

}

};

// Example function to test

async function executeContract(account, contractName) {

// Replace with actual function implementation

return new Promise((resolve, reject) => {

const { tx } = await account.functions[contractName].
