- Allowing users to change the light color of a Basil plant
This is a sample Dapp built on top of ZOS (ZeppelinOS). It presents a basic contract Basil.sol and then uses an AppManager from ZOS to upgrade the contract to BasilERC721.sol using a proxy that preserves the original contract's state, while mutating its logic. The upgraded contract also makes use of ZOS' on-chain standard library, connecting to a proxy of the MintableERC721Token implementation of the openzeppelin-zos release. As for functionality, the Dapp allows users to change the light color of a Basil plant, using an Arduino and an RGB wifi light bulb. The upgraded contract also emits an ERC721 non fungible token to the user.
