Smart contracts are self executive contracts that execute itself with agreement written in a direct way in lines of code. Smart contracts have been giving a lot of a tension from some years because of their tension for automation of multiple processes and for enhancement of efficiency but as smart contracts are increaseing then requirement for auditing is also increasing as it is very important so I would like to talk about it today with all of you.

Smart contract auditing is phenomena of review and analyse code of smart contract for identification any vulnerability about security is present, any bugs or errors or any kind of insufficiency. Major purpose of auditing is give surety that smart contract functions is intended to does not create any kind of error or bugs that can exploit by malicious actors or hackers.

Smart contract auditing is most important I am talking about it but what are the reasons behind its importance now I am going to highlight this concept. First of all smart contracts are immutable so it means that when they will deployed then they cannot be altered and attitude so this is making it crucial for ensuring that contract will remain free from any bugs before its deployment.

Smart contracts are also useful for online handling of greater amount of funding and sensitive information which make it major target for hackers so if there is any single vulnerability or error in smart contract then it can cause a lot of financial losses and can cause damage to reputation.

Auditing of smart contract conduction requires auditors that are following a structured approach. It includes to review code of contract for identification of bugs or any vulnerability if it is present and so providing certain solutions or recommendations for further improvements or for avoiding them.

Auditing process always start with making reviews of functions and intended behaviour of a particular contract. It includes to make analysis of code of contract and identification of multiple functions and variables and having a know how that how these are interactive for each other.

When auditor will have an accurate understanding about functions of contract then they can start identification of potential vulnerability, bugs or weaknesses that they are present or not and it include the usage of multiple tools and techniques like making static analysis, making dynamic analysis and fuzz testing

Static analysis is made or performed to review code of contract which is used for identification of any kind of bugs or vulnerability presence and this process or this analysis contains assessment or checking which include reentrancy attacks and front running attacks.

Dynamic analysis is important for testing functions of contract so that bugs baby identified and their input validation of contract handling of error and giving access to control is monitored.In fuzx testing unexpected input is to contract for checking its response and vulnerability that cannot be checked by analysis or other testing forms can be checked by fuzz testing.

There are some of the recommendations that can be provided for improvement by these contracts auditing and it include to update code of contract that is useful for fixing any bug, enhancement of contract function and optimization of contract performance. That was all about smart contract auditing their purpose and kind of improvements that the offer in form of recommendations.Hopefully, this topic is clear for everyone.....
