Mint-A-Frame

Introduction: We created the Mint-A-Cast frame to empower creators and users. We wanted to solve 2 problems:

• How do we have on-chain attribution for users who save casts?
• How do we reward creators for quality, popular casts?

Our Mint-A-Cast frame solves these two problems. First, the frame allows users to mint banger casts and allows them to have an on-chain record of casts they like. Second, creators (cast authors) can set a fee when their casts are minted; this gives creators another avenue of revenue. Creators also have a way to track users who are rewarding them for their content; this gives another directory to content creators to possibly reward their followers. With the Mint-A-Cast frame, users directly reward creators for quality content thus increases the reward for casting quality content.

MVP Summary: Through the use of this frame, the user can mint a cast as an NFT. Currently, the user will need to visit the site – https://frameworks-ri-ja-seven.vercel.app – to paste the URL to upload the metadata. Afterward, they use the link provided to cast that will spin up a frame. This single-frame will allow users to mint casts directly from the Warpcast platform. Currently, the cast creator can set a minting fee by interacting with the contract directly as well as withdraw funds.

MVP User Flow:

1. Find a cast they like; copy the cast link (format: https://warpcast.com/[castAuthorName]/[castShortHash])
2. Navigate to the website https://frameworks-ri-ja-seven.vercel.app
3. Past URL into input box, click button to next step
4. Follow Transaction pop-up in order to use the Pinata SDK to upload the IPFS
5. Copy the link to the frame generated.
6. Either cast this link to spin up the frame or use a debugger like frames.js to see the frame.
7. Click mint & sign the wallet pop up
8. Wait for the transaction to complete

Currently, the Mint-A-Cast website and frame is usable to mint any cast; so no customization is required beyond providing the cast link. You can use the link to the blockchain explorer to see recent mints: https://sepolia.etherscan.io/address/0x4dd9ed609abbb6ae489045a678ff3080d3f4106c

Roadmap:

1. General Improvements:

• Launch production to Base Mainnet; currently, dev environment is on Sepolia
• Switch from Wield API to Pinata Farcaster API when they accept the short hash and username for cast look up.
• Create multipage frame
  • First Page
    • Allow users to input cast link into first frame
    • Submit button & transaction to upload metadata IPFS
  • Second Page
    • Show picture preview of cast
    • Mint button & transaction to mint NFT
  • Third Page
    • Show success image
    • Link out button to blockchain explorer
• Deploy an 1155 contract per creator from first mint
• When the same cast is minted, it will have the same token id; hence, using ERC 1155.
• Each NFT will have attributes to show:
  • Date
  • Author Name
  • Channel cast was made in
• Make sure contract follows standards to be minting with Warps
• Small ~$0.10 fee for each mint to go to us (Ricy & Jamie) to help cover cost to maintain the Frame

1. User Improvements

• The frame's input with be able to accept the cast URL or a full cast hash input
• After the first mint, when the user shares their minted cast other users can mint the same cast with Warps through Warpcast.
• User will have a Mint-A-Cast web client to browse Farcaster
  • Minting cast is an embedded function
  • Users can use any currency (cross chain execute; full chain abstraction)
  • User can create their own custom Mint-A-Cast frame for specific casts of theirs

1. Creator Improvements

• Creation of a web client front end for creator tools including but not limited to
  • Set mint pricing (e.g. 0.001 ETH)
  • Set mint limit amount (e.g. 10 total)
  • Set mint time limit (e.g. 1 day)
  • Unmintable Cast (disabled minting on some casts)
  • Airdrop minted casts to previous supporters
  • Allowlist minting
  • Subscription to cast minting (through Hypersub)
  • Specify currency received (e.g. Base ETH, DEGEN)
  • Allocate profits directly to an address withouth needing to withdraw

The contract is a erc1155 smart contract, https://sepolia.etherscan.io/tx/0x4b50fa82925f3417af973bddf057a074345efe818a6491e898f057f898141f23. The contract is deployed on Sepolia and developed with Hardhat. It also provides interface for authors to adjust price and withdraw profits.

The frontend is a NextJS project. Using Framejs to achieve single page minting frame. This Mint-A-Cast frame is to present users with the cast image of the nft they can mint with a the mint button. The mint button would allow users to send transactions to Sepolia chain and the transaction would also send some ETH as the fees to buy/mint the nft. After users have submitted the transaction, the frame returns a transaction submitted frame with transaction hash. To convert a cast into NFT, the project is using APIs by Wield to retrieve related data and using the Pinata SDK to upload metadata to IPFS.
