Rewarded Interest engaged me to perform an early-stage technical audit of their design and architecture—including source code and cryptographic design. My assessment indicates that the solution as reviewed is fundamentally sound, providing granular consent controls and full transparency. The team quickly implemented my recommendations. Furthermore, the early consideration of data protection aspects is a signal of adherence to Privacy by Design from the start. In the current complex regulatory-technical environment, Rewarded Interest represents an innovative approach that may help bridge the gap between consumer protection and data protection rights.
