🚀 Automatic NFTs Generator

Our program consists of a group of smart contracts, which automatically interact with a single smart contract: VjkNFT.sol: 0x4A9f1122c1898DE7218B5eF5b49c4EFEB23Db1D6 Goerli, and a react application to interact with this contract:

  • Swaper.sol Contract responsible for swapping ETH for ChainLink token. All automation of our software is done using tools supported by ChainLink. Before starting any process, we need ChainLink Token.
  • APIConsumer.sol Contract responsible for interviewing Kenny West, and returning us an epic quote, hehe.
  • VRF.sol Contract responsible for requesting some random numbers using ChainLink VRF, with those numbers, the same contract creates a unique SVG.
  • VjkNFT.sol Main contract responsible for automating the entire process and storing the entire collection of NFTs and remaining ChainLink tokens.

☕ Using VjkNFT

To interact with our application and create a unique NFT go to: vjknft.web.app.

You can also clone this repository, change contracts in smart_contracts folder.

You can use our client application and interact with contracts already deployed on Goerli testnet.

📇 Process

Our application consists of a button to create a new NFT and a section to show all the NFT created in this collection. However, several steps are followed automatically during creation:

1º: Require before start to generate nft, swap the amount paid by the user in ETH to ChainLink Token, using Swaper.sol. After Fund APIConsumer.sol and VRF.sol.

2º: Request KennyWestAPI quote through a ChainLink API call, get the quoteID. Request one single SVG via ChainLink VRF, get the svgID. Mint one tokenID with those IDs.

3º: Create a upkeepID by tokenID and finish to mint. Now the user have paid ChainLink and have they set of ID to proove it.

4º: ChainLink will keep checking APIConsumer.sol and VRF.sol if quote and svg exists.

5º: When both contracts finish creating quote and svg, our ChainLinkUpKeep will set the tokenURI (link this information with our tokenID). And after that, cancel upkeep to not spend more ChainLink Token, and send the remaining amount to VjkNFT.sol.

6º: All the ChainLink Token remaining (profit), can be checked contractLinkBalance() and withdrawn withdrawLink().

Our dapp will guide you through the whole process.

🎚️ Adjustments and improvements

The project is still under development and the next updates will focus on the following tasks:

  • Contracts - Fully Automated
  • Transactions - Gas Optimization
