Dynamic NFT with Chainlink Automation

Create a Dynamic NFT that evolves over time using Chainlink Automation. This project utilizes smart contracts to change the NFT's metadata based on time intervals, simulating the growth stages of a flower.

Getting Started

Deploying the Contract

1. Deploy on Remix: Use the provided Flower contract code. Set the UPDATEINTERVAL constructor argument to your desired time interval (in seconds).
2. Verify Inputs: After deployment, call interval, name, and symbol functions to confirm your inputs.

Minting Your NFT

1. SafeMint Function: Call safeMint with your injected provider wallet (ex. Metamask) address to mint your NFT.
2. Contract Address: Copy the deployed contract address.
3. View on OpenSea: Go to testnets.opensea.io and paste your contract address in the search bar to view your NFT. Ensure the Token ID is 0.

Setting Up Automation

1. Chainlink Automation: Visit automation.chain.link and select "register new upkeep."
2. Custom Logic: Choose "custom logic" and input your contract address.
3. Upkeep Name: Enter a name for your automation job.
4. Starting Balance: Allocate 3 LINK tokens for the starting balance.
5. Register: Leave other fields as default and register your upkeep.

Growing Your Flower

1. Interact with Contract: Return to Remix and call the growFlower function with your Token ID (0).
2. Wait and Refresh: After the set interval, refresh your NFT on OpenSea. You should see the updated metadata.

Contract Functions

• safeMint: Mint your NFT with an initial stage.
• growFlower: Triggers the next growth stage of your NFT.
• flowerStage: Returns the current stage of the flower.

Chainlink Automation

This project utilizes Chainlink Automation to periodically call the growFlower function, simulating the growth process of the flower. It ensures that your NFT dynamically updates without manual intervention.

Exploring Your NFT

Your NFT will evolve through predefined stages, with each stage represented by unique metadata stored on IPFS. Starting as a seed, your flower can sprout and eventually bloom, visualizing the lifecycle of a plant.

Conclusion

This guide provides the steps to deploy and interact with a dynamic NFT using Chainlink Automation. By following this guide, you can create an NFT that grows over time, offering a unique digital collectible experience.
