AI Minter

Dreams to NFTs: AI Image Generation & Minting built with Replicate Models and MintbaseJS.

Tooling:

Author:

• @mintbase.js/sdk: to use the execute call when minting

• @mintbase.js/react to provide the wallet connection

• @mintbase.js/storage: to upload the images to Arweave

Project Walkthrough

By writing a prompt and selecting a model from the dropdown, users can generate an image through AI when pressing the prompt button. If the user then wishes to mint the resulting image, they may add a title and press Mint Me which will then redirect them to the transaction page so they can finish the minting process.

Pre-Setup - Proxy Contract

• You need to have a NEAR Contract where you add a proxy contract as a minter.
• The proxy contract enables non-minter users to mint images on your contract.
• The Near Contract will be where the NFT images will be minted.
• The proxy contract will be the minter.
• The user wallet address will be the owner of the NFT.

Deploying a Near Contract on Mintbase:

1. Login on Mintbase and access Contracts Page
2. Click on New Contract
3. Choose Store Name (this will be the contract address to add on your minsta instance, this need to be added on the process.env.NEXT_PUBLIC_NFT_CONTRACT_ADDRESS environment variable) and Store Symbol
4. Proceed to transaction.
5. Succeeded
6. Go to Contract Settings

Add Proxy Minter Contract

1. Under Contract Settings go to Minters
2. add 0.drop.proxy.mintbase.near (this is the contract address that need to be added on process.env.NEXT_PUBLIC_PROXY_MINTER_CONTRACT_ADDRESS), and click Add Minters.
3. Proceed to transaction.
4. Succeeded

Setup

you should create an .env file with the following properties:

REPLICATE_API_TOKEN='...'
NEXT_PUBLIC_MINT_CONTRACT_ADDRESS='...'
NEXT_PUBLIC_PROXY_CONTRACT_ADDRESS='...'
NEXT_PUBLIC_NETWORK='...'

REPLICATE_API_TOKEN should have the value of your token for the replicate api. You can get a token on the replicate website.

NEXT_PUBLIC_MINT_CONTRACT_ADDRESS is the address of the contract where you want to mint the result into an NFT. If you dont have one, you can deploy a new contract on our launchpad.

NEXT_PUBLIC_PROXY_CONTRACT_ADDRESS is the address of a proxy contract to allow you to relay the transaction to the minting address. This address should have minting permissions on your minting contract.

NEXT_PUBLIC_NETWORK is the network of the contracts being used (usually 'mainnet' or 'testnet').

Run project

After setting up, you can run:

pnpm install

After the install succeeds, you con start the project with:

pnpm dev

And you're done! The project should be running locally on your machine.

Extending

This project is set up using Next.js + @mintbase/js + shadcn ui + react hook form. You can use this project as a reference to build your own, and use or remove any library as needed.
