Omniscia Nevermined Audit
Data Marketplace Security Audit
We were tasked with auditing the codebase of Nevermined and in particular their core provenance-aware NFT implementation.
The system implements a decentralized identifier system which can be associated with a particular NFT and whose provenance is handled by a W3C compatible sub-system.
Over the course of the audit we were able to pinpoint several Solidity-specific issues ranging from mathematical overflows to hash colissions which we strongly urge the nevermined team to remediate as soon as possible.
During the audit, we filtered and validated a total of 2 findings utilizing static analysis tools as well as identified a total of 16 findings during the manual review of the codebase. We strongly recommend that any minor severity or higher findings are dealt with promptly prior to the project's launch as they introduce potential misbehaviours of the system as well as exploits.
The list below covers each segment of the audit in depth and links to the respective chapter of the report:
