Debugging is an important exercise when authoring Solidity smart contracts. Debugging refers to finding issues, bugs, and removing them by changing code. It is very difficult to debug a smart contract if there is in adequate support from tools and utilities. Generally, debugging involves executing each line of code step by step, finding the current state of temporary, local, and global variables and walking through each instruction while executing contracts.
There are the following ways to debug Solidity contracts:
- Using the Remix editor
- Events
- Block explorer
