Why is third party audit necessary?

Smart Contract Audits are important because they help you identify your biggest security risks so you can make changes that will protect your company from those risks.

What is difference between instant(express) audit and Full Audit?

Express audit is to generate instant report of any basic security risks present in the smart contract using automated tools. Full service audit is where our security expert team tests the smart contract thoroughly and brings to light any minute possibility that might harm it's security.

When is the best time to audit your smart contract?

Although getting your smart contract audited before going live on mainnet is "Best Advisable", but there have been instances where smart contracts have been hacked after a year of going live. So getting your smart contract audited even though you are live and running advisable.

Which types of contracts do we audit?

As of now, we audit smart contracts for utility tokens, security tokens, dApps, protocols, solutions at POC/MVP and deployment level.

How long does it take to audit each contract?

In express audit, the report is generated instantly and in Full audit, we require 7-10 days to generate the full report.

How is QuillAudits different from other 3rd party auditors?

While other platforms use a particular tool each to audit, QuillAudits uses best features from multiple tools (Oyente,Solidity-Coverage, Mythril , Maian and Securify ) to audit your smart contract.
