Hackathon NFT Breeding

This is my winning hackathon NFT project during the Genesis Blocks hosted by BreederDao last August 2022. This project allows on-chain breeding mechanism using a gene crossover algorithm and Chainlink for randomness and mutation.

Getting Started

1. Make sure you fill in these environment variables

Note: Each directory (contracts, frontend, server) must have a separate environment file

# Contracts
INFURA_API_KEY
ADMIN_PK
ETHERSCAN_API_KEY
GOERLI_VRF_COORDINATOR
GOERLI_GASLANE
GOERLI_SUBSCRIPTION_ID
GOERLI_TOFFEE_ADDRESS
GOERLI_TOFFEE_EXCHANGE_ADDRESS
GOERLI_TOFFEE_PETS_COLLECTIBLE_ADDRESS
GOERLI_GENE_CROSSOVER_ADDRESS

# Frontend
NEXT_PUBLIC_TOFFEE_COLLECTIBLE_ADDRESS
NEXT_PUBLIC_TOFFEE_ADDRESS
NEXT_PUBLIC_EXCHANGE_ADDRESS
NEXT_PUBLIC_GENE_CROSSOVER_ADDRESS
NEXT_PUBLIC_API_URL=http://localhost:8080/api

# Server
PINATA_API_KEY
PINATA_SECRET_API_KEY
PINATA_JWT

2. Deploy the contract

npx hardhat run ./scripts/deploy.ts --network goerli

3. Verify the contract

npx hardhat run ./scripts/verify.ts --network goerli

4. Start the frontend

npm run dev

or

yarn dev

5. Start the server

npm run dev

or

yarn dev

Contract Addresses

You can check the sample contract addresses at GoerliEth

TOFFEE_COLLECTIBLE_ADDRESS=0x43803c69AE20C2aCCdC4AbD76C3167DCc5cb9B94
TOFFEE_ADDRESS=0xF22CDE739b1b3274Da38700424e3fE66d2174146
EXCHANGE_ADDRESS=0x6Cb095D9fa8459f46e7c27B0944F0626BDDB2feD
GENE_CROSSOVER_ADDRESS=0x901cf5F9F6B17Cf5e145bca8B54B4E72bd59D346
