End-To-End NFT/ERC-721/Blockchain Collectible tutorial. We
End-To-End NFT/ERC-721/Blockchain Collectible tutorial. We deploy some adorable puppies.
We've made some updates to this code! Feel free to follow along with the video, but we made a lot of nice improvements to the repo here:
✨ Updated Code: https://github.com/PatrickAlphaC/nft-mix
Deploy your smart contract to Opensea, end-to-end. The Ultimate/end-to-end tutorial.
UPDATES:
🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺🔺
1. ValueError: The private key must be exactly 32 bytes long, instead of 0 bytes.
If you get this error, add a "0x" to the start of your metamask private key.
Follow this if you are getting gas estimation errors (But for Rinkeby instead of Kovan): Set Up Your Environment for Success |...
2. requestRandomness no longer requires userProvidedSeed. However, if you use version 1.0.2 of the chainlink-brownie-contracts in your brownie-config.yaml as done in the video, you can ignore this.
3. Skip running `source .env` and instead just make sure in your `brownie-config.yaml` you have `dotenv: .env` and all your environment variables in your `.env` file.
4. We have added a `listen_for_event` function instead of doing `time.sleep`
5. (not done) If someone wants to implement this with Chainlink VRFv2 that would be cool 😊 You can still follow along with everything, but skip the Chainlink section if it's confusing!
