# Chainlink Random Character Creation
This repo is a starting point for creating:
1. NFTs built with provable RNG using the [Chainlink VRF](https://docs.chain.link/docs/get-a-random-number)
1. NFTs built with verifiable RNG using the [Chainlink VRF](https://docs.chain.link/docs/get-a-random-number)
2. Create dynamic NFTs that change based on real world data. [By using decentralized oracles to get data.](https://docs.chain.link/docs/make-a-http-get-request)
3. Adding your randomized NFTs to the [OpenSea Marketplace](https://opensea.io/)
We will easily create our own NFT on the Rinkeby Chain. We can edit the name of the character in the [`generate-character.js`](./scripts/generate-character.js) script. Right now, the character defaults to "Garfield the Chainlink Warrior".
