Interesting to see a ERC-721 project to put all blockchain projects into a transactional based protocol that will encapsulate blockchain transactions into non-fungible smart contracts. Technological aspect might have to work on implementation and integration more compared to standard ERC-20.
Agreed, The AER token will be an ERC-20, we are using ERC-721 as an encapsulation token to be generated with AER for storing all transaction data from a particular user in the blockchain and accessible via our block explorer.
