Inspiration

Virtual pets: Tamagotchi + Digital property: Decentraland + Play to earn: Axie Infinity + Virtual farming: Farmville + Yield farming

What it does

We built an on-chain mobile-friendly virtual yield farming game on Polygon using Chainlink VRF to provide entropy for fair distribution of game items. There is a NFT minter using NFTPort saving data on IPFS. There is an internal decentralized exchange (DEX) to trade earned items for MATIC (custom wrapped version) and dynamically price your yield.

How we built it

Solidity (multiple versions) for game contracts and multiple ERC721 and ERC20 token contracts. The game can be played entirely on chain through calling contract functions (e.g. on Etherscan).

Big thanks to scaffold-eth for the boilerplate.

Chainlink VRF is used to call back our contract with randomness which is used to set various traits of our plants so players can't know what kind of seed they get ahead of time.

Contracts are currently deployed on Polygon (Mumbai).

Decentralized exchange contract (Sushiswap/Uniswap) is deployed for trading the fruit tokens that you earn in the game.

NFTPort is used to mint snapshot NFTs of game items on Polygon.

We store the NFT's image on IPFS using NFTPort.

GitHub Pages serves the frontend.

Challenges we ran into

Setting up a mock of Chainlink VRF. But most challenging was retaining team members throughout the hackathon as many members had to leave.

Accomplishments that we're proud of

The game is working on a public blockchain and hosted online and works well on mobile (via Metamask). The game is fast and fun to play. There is an in-game decentralized exchange for the fruit tokens that are yielded.

What we learned

Chainlink + VRF. How to deal with Polygon.

What's next for Plantation

Finish up some yield farming features, get more artwork, expand to more chains and integrate more assets.
