This is the answer to stackoverflow question: Error: cannot estimate gas; transaction may fail or may require manual gas limit (Sepolia test Network) Overview The EventWinner project showcases a smart contract that can interact with other contracts through their interfaces. It implements a pattern for making external calls to contracts that expose an attempt() function. Technical Stack - Solidity ^0.8.27 - Hardhat - TypeScript - Ethers.js Contract Architecture EventWinner.sol The main contract contains: - Interface definition for target contracts - External function to interact with other contracts - Low-level call implementation for robust contract interaction Key Features - External contract interaction - Interface-based calling - Gas-efficient implementation - Error handling Usage The contract can be used to interact with any contract that implements the attempt() function: Development 1.
