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

As a Next.js developer, you’re 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 bit more complicated. Specifically, you’ve encountered an error message that looks like this: “RPC Error: Execution Revoked”.

At first glance, this might seem like a straightforward issue related to contract addresses or ABI versions. However, before jumping to conclusions, let’s dive deeper into what’s going on and explore potential 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 due to a variety of factors, including:

  • Smart contract logic errors

  • Transaction validation issues

  • Interoperability problems with other blockchains

When a smart contract’s execution is revoked, it means that the transaction or function call was rejected by the blockchain because of an internal conflict or error.

Why might this error occur?

To better understand what’s going on, let’s take a closer look at the code. Assuming you’ve set up your Next.js project with MetaMask integration, here are some potential causes:

  • Contract address mismatch: If the contract address provided in your useMetaMask hook doesn’t match the actual contract address deployed on the blockchain, it can lead to an execution revocation error.

  • ABI version mismatch: Even if you’re using the correct contract ABI, there might be a conflict between the ABI version required by MetaMask and the one used by your code. Make sure you’re importing the latest ABI versions for all contracts involved.

  • Smart contract logic errors

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

Troubleshooting steps:

To resolve this issue, try the following:

  • Verify contract addresses and ABIs: Double-check that your contract addresses are correct and ABI versions match both MetaMask’s requirements and yours.

  • Update Next.js code to match MetaMask’s contract address: Make sure your useMetaMask hook is using the correct contract address, even if it’s a different one than what you provided in your code.

  • Check for smart contract logic errors: Review your code to ensure there are no syntax or logical mistakes that could be causing execution revocation errors.

Example use cases:

Here’s an example of how you might modify your useMetaMask hook to verify the contract address and ABI:

“`jsx

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

import { useContract } from “next-use-contract”;

const Metamask = () => {

const { account, setAccount } = useMetaMask();

const executeSmartContract = async (contractName) => {

// Verify 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 with

async function executeContract(account, contractName) {

// Replace with your actual function implementation

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

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