SimplyVital Health Passes Security Audit — Hosho Group

SimplyVital Health Passed Security Audit

After writing the smart contracts to be used with health cash (HLTH), our ERC 20 token, we decided it would be best to work with an outside security partner to audit our code and make sure we are providing the most secure experience possible to our soon-to-be token holders. To date more than 300 million dollars has been lost or stolen due to smart contract flaws; a figure we are determined not to add to.

We worked with Hosho Group to create an actionable security report to insure our smart contract performed as expected and to bug test our code. We followed that up with immediate updates to address any issues. The results were stellar; everything passed review.

To Summarize

Our Transmute contract that exchanges our ERC 20 token (HLTH) for Health Cash on the Health Nexus blockchain was without issue. Our HealthDRS contract that provides our initial decentralized record service was found to have issues in the logging functionality preventing some participants from creating log entries as expected. These issues have been fixed and the contract reviewed again.

“During​ ​ the​ ​ initial​ ​ static​ ​ analysis,​ ​ several​ ​ possible​ ​ vulnerabilities​ ​ were​ ​ noted,​ ​ and​ ​ the​ ​ SVH​ ​ team was​ ​ very​ ​ quick​ ​ to​ ​ patch​ ​ these​ ​ and​ ​ return​ ​ the​ ​ updated​ ​ code.​ ​ They​ ​ implemented​ ​ the​ ​ required​ ​ fixes to​ ​ ensure​ ​ the​ ​ long-term​ ​ health​ ​ and​ ​ stability​ ​ of​ ​ the​ ​ HealthDRS​ ​ system​ ​ as​ ​ it​ ​ works​ ​ within​ ​ the Ethereum​ ​ ecosystem.​”
