Hi, chiming in from Aave Grants.
Putting the merits of cryptos potential to impact the food industry aside, the primary reason this was rejected was that it is not Aave-centric enough. This would have been outlined in the follow-up email you received.
Aave Grants gives grants to grow and strengthen the Aave protocol and ecosystem. Take a look at a running list of grants we’ve awarded since January to get an idea of the different types of benefits projects bring such as increasing liquidity flows, building new capabilities on top of Aave or producing novel insights about Aave for the community.
