Panda NFT

Inspiration

Miniting NFT should be fun! Gamification is brought into NFT minitng through Chainlink keeper and Chainlink VRF v2.

What it does

Each day Chainlink keeper will increase the mint price of the NFT. You can either mint based on a daily increasing fee or pay a fixed fee to enroll into a luck draw, supported by Chainlink VRF v2, to get 10 NFTs !

How we built it

• The smart contract was written in Solidity (ERC721A) using Hardhat
  • Chainlink keeper was used to call the increaseMintFee daily
  • Chainlink VRF was used for the randomness
• The front-end was built using React, with Rainbowkit and Wagmi / view, hosted on Vercel
• Dapp was deployed in both Sepolia and Goerli

Challenges we ran into

• Issues related to using Chainlink keeper and VRF
• Issues related to front-end to have the best UX

Accomplishments that we're proud of

• The dapp is fully functional !

What we learned

• Improved skills in smart contract development
• Improved skills in front-end development
• Improved understanding in Chainlink products

What's next for Panda NFT

• Have more gamification features !
