Smart contract hold assets of millions of worth, all the issues and security flaws must be solved before deploying on mainnet.
Secure code have high chances of project success and also it will help in listing your token or projects on exchanges.
Your code should justify your use-case.
If your smart contract Verified by 3rd party Auditor, it gain value in market as well as attract investor.
Decentralised applications are recognised as combination of smart contracts + web interface + wallet, Smart contract audit is not enough for a Dapps, as web interface, backend and wallet must undergo for penetration testing to prevent any attacks on dapp.
Smart contract audit is a process of validating functionality of a smart contract and to find a security loopholes of smart contracts and correct them, our rigorous smart contract audit process is enough to prevent your smart contract from known attacks and other vulnerabilities.
We follow Smart Contract Weakness Classification (Scw registry) to standardised vulnerabilities of smart contracts and to define a common language for describing security issues in smart contract systems architecture, design, or code.

Ethereum Smart Contract Audit is a process of validating functionality of a smart contract and to find a security loopholes of Smart Contracts and correct them.
Ethereum Smart Contract Audit is for everyone who is dealing with smart contracts, either you have an ICO, STO, fintech, Games or any Dapp solution based on Smart Contract you should go for third party Audit
Ethereum Smart Contract Audit assured that functionalities of smart contract is working properly and there is no loophole for attackers to attack on your smart contracts.
Following are the things you need to know before starting Ethereum Auditing:
1. Correct Functions Visibility:- Functions in solidity can have four visibility specifiers.Absent specifiers can be dangerous especially in the case of functions where the default is public accessibility. If such a function has critical logic then it can be triggered from any external address to potentially misuse the contract.
2. Oracle calls:- Blockchains cannot access data outside their network. An oracle is a data feed provided by third party service designed for use in smart contracts on the blockchain.
3. Check for re-enterancy and ensure state committed before external call:- Reentrancy occurs when external contract calls are allowed to make new calls to the calling contract before the initial execution is complete.
4. Don’t delegatecall to untrusted code:- The delegatecall function is used to call functions from other contracts as if they belong to the caller contract
