What are smart contracts?
Smart Contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. They are a high-level programming language, which means they can create conditions where money will automatically be sent from one digital wallet to another when certain conditions are met. Companies provide smart contract audit services in order to ensure that their clients' projects meet their intended functionalities and are bug free.

Why do companies provide smart contract audit services?
Smart contract audit services are provided by companies because smart contracts are immutable once deployed to the blockchain. They cannot be updated. Therefore, it is important for companies to hire a company that can help them in auditing their smart contracts before they are deployed on the blockchain.

Why are smart contract audit services necessary?
Smart contract audit services are very necessary for the companies to check whether there is any loophole in their smart contracts. Through the help of smart contract audit services, you can identify the issues and rectify them before starting the token sale.
