Crossmint Mint Frame

Overview

Web App that allows you to create a recast-then-mint frame for Farcaster. Use this to promote your posts and allow your followers to own a piece of them.

This app is built with Vercel edge functions using NextJS 13, Crossmint for NFT minting, and Farcaster as the distribution channel.

Project set up

Clone this repo and install dependencies.

git clone git@github.com:Crossmint/frame-minter.git
cd frame-minter
yarn

Create a Crossmint project and obtain an API key:

1. Go to www.crossmint.com/console and sign up (if you're testing on testnets, use staging.crossmint.com/console instead)
2. Navigate to the Billing and Usage tab and top up credits (this only applies if you're in production). Credits are used to pay for minting fees.
3. Finally, go to Api Keys, create a new Server Side Key, and give it the nfts.create and nfts.read scopes. Save this key for later.

Create an NFT collection from the Collections tab in the console. Once created, tap to Create an NFT, and fill in the details. Set the supply to unlimited.

Copy the template ID of the NFT. // TODO: this doesnt work in the UI and needs calling the API

Edit const.ts and fill in the values
