Game Farming by Luan Pontolio

About

Game-Farming is a simple bounty project based on game items.

The project allows users to redeem rewards for each NFT item they put in the Pool. When creating a new position, the Staker start to earn a project token(RKN). The image below shows us how this works:

Contracts Design

• Pausable: The contract pauses the rewards distribution by the owner(RewardsDistribution).
• RewardsDistributionRecipient: To add and verify a new RewardsDistribution.
• YieldFarmingWithNFT: Primarily contract. Its initialization parameters have cared for RewardsToken, StakeToken, and RewardsDistribution. In its initialized state with the RKN distribution period of seven days(only the RewardsDistribution has the authority to change the period). If staked a new NFT in the contract, the _totalSupply receives 1 ether(for each successful stake), and the user increases their balance for each NFT added.

Setup checklist

• Node 16.14.2
• Yarn 1.22.19

Metamask

1. Be sure to have metamask plugin installed in your browser (recommended browser is Chrome)
2. Login to Metamask and point the network to localhost and port 7545 before starting the frontend app
3. Install ganache https://trufflesuite.com/ganache/.

Quickstart: Running local

1. Open a new terminal window and run git clone https://github.com/luanpontolio/game-farming && cd game-farming
2. run yarn to install backend dependencies
3. run yarn test to run contract test suite to run smart contract test cases
4. run DEPLOY_PATH=scripts/deploy.ts yarn deploy:local to compile and deploy the Game-Farming contracts to the ganache node
5. cd to frontend cd frontend
6. run yarn to install frontend dependencies
7. run yarn dev to serve the app locally

Environment Setup

Quickstart Setup

• Install all dependencies
• Deploy a local ethereum network with Ganache
• Compile and deploy smart contract to the blockchain
• Contract artifact and typechain is auto generated in the frontend folder

Terminal Setup Checklist

• Terminal 1 - React Front End for the dapp
• Terminal 2 - If you not running with Ganache interface, you can run npx ganache-cli -p 7545 -e 100000000000 -l 10000000000000

Dapp Setup Checklist

• Deploy the local ganache
• Metamask set to the network you are developing to (localhost:7545 for local, testnet of choice)
• Run a local react server

Smart Contract Development Setup Checklist

• Contract and other dependencies are in the same folder

Tutorials

Deploying contracts in Local

1. Ensure your local environment has been set up (ganache node, truffle console)
2. Run yarn test to ensure all tests are passing (make sure you have the setup your local environment first)
3. Make sure your ganache is running and open localhost:7545
4. If tests are passing running DEPLOY_PATH=scripts/deploy.ts yarn deploy:local
5. The contracts addresses and the owner address will show up on terminal.
6. Run the dApp: cd frontend && yarn dev
7. Change your metamask network to localhost
8. The Game-Farming dApp UI should load

Troubleshooting

1. Error: Cannot use JSX unless the '--jsx' flag is provided

• Follow: https://vscode.readthedocs.io/en/latest/languages/typescript/#using-the-workspace-version-of-typescript - "Using the workspace version of TypeScript" section

2. Warning: Calling an account which is not a contract

• Compile and deploy your contract first. Run npm run deploy:local for local deployments.

Guidelines:

• Name your branches starting with branchName. Ex. doingSomethingNew or fixSomething.
