Debugging Tools
1. Hardhat
Hardhat is an open-source tool and built-in developer for developing, deploying, and testing smart contracts. It is a tool based on JavaScript to develop Ethereum-based applications. It provides developers with a huge range of functions to make smart contract development easy.
2. Truffle
Truffle is a framework for Ethereum smart contracts. Truffle tools help with developing, deploying, and testing these contracts. It contains a Truffle debugger for debugging smart contracts.
3. Remix
Remix is an editor for Solidity which contains an in-built debugger for debugging smart contracts. Remix is IDE used for developing and deploying smart contracts easily using Solidity programming language. It can test, deploy and debug smart contracts.
4. EtherScan
EtherScan is a blockchain explorer for Ethereum used to inspect and debug the smart contracts deployed on Ethereum. It is used to visualize data in the blockchain. It tracks the transactions and smart contracts in the blockchain.
How to Debug Ethereum Smart Contracts?
Ethereum smart contracts are the collection of code and data which is present in the Ethereum blockchain at a well-defined address. It is a block of code that runs on blockchain. It is a program that executes on the Ethereum blockchain. Smart contracts execute automatically. These contracts form the basic blocks of the Ethereum blockchain.
Debugging smart contracts is the process of analyzing the internal work of the transaction sequentially. Debugging allows us to find and fix the errors in the smart contract. Debugging checks the smart contract functions whether generates the desired output.
Debugger provides the functionality to debug a transaction sequentially to analyze the space, cost, and cost after each step. Debugger finds and fixes the error in the smart contracts. It also checks the functions that perform the specified task.
