The HEX contracts in Solidity programming language are very well written and properly documented. The fully functional and operational DEFI smart contract on the Ethereum blockchain has as of spring 2020 more than 200000 unique wallets addresses holding HEX.
Richard Heart has taken the effort to have the HEX Solidity smart contract being audited 3 times, of which 2 are technical and 1 economical. One of the auditor’s was Coinfabrik was founded in 2014 and has completed over 80 projects in the public and private blockchain sector.
CoinFabrik works in areas such as development, research, security auditing, and consulting. CoinFabrik is specialized in providing cryptocurrency software development services and regarded as one of the best in the world.
In the crypto audit there are multiple severity classifications:
Critical: The issue puts a large number of users’ sensitive information at risk,or is reasonably likely to lead to catastrophic impact for client’s reputation or serious financial implications for clients and users.
Medium: The issue puts a subset of users’ sensitive information at risk, would be detrimental for the client’s reputation if exploited, or is reasonably likely to lead to moderate financial impact.
Minor: The risk is relatively small and could not be exploited on a recurring basis, or is a risk that the client has indicated is low-impact in view of the client’s business circumstances.
Enhancement: The issue does not pose an immediate threat to continued operation or usage, but is relevant for security best practices, software engineering best practices, or defensive redundancy.
Coinfabrik found 1 minor severity in the HEX contract, it is not part of the user interface and the probability of finding a collision is extremely low with available hardware of today. No critical or medium severities have been found at all in HEX.
This is a huge compliment for the HEX project the game theory embedded in it can still surprise us as we go along in time, as this is the first time deposit CD ever on the blockchain being introduced.
