Project Walkthrough

This is a simple minter example built on top of Next.js 14 using some of @mintbase-js packages.

NOTE: As a standard on Mintbase as we use the latest versions of Next.js we recommend using pnpm, but the package manager is up to your personal choice.

if you dont have a store you can deploy a new contract on our launchpad

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

In the minter/src/config/setup.ts file, we define several key configurations for interacting with the Mintbase platform. This setup is crucial for ensuring that our application communicates correctly with Mintbase smart contracts.

ENV Variables

• proxyAddress: This is the address of the proxy contract on Mintbase. It is either taken from the environment variable NEXT_PUBLIC_PROXY_CONTRACT_ADDRESS or defaults to "0.minsta.proxy.mintbase.testnet" if the environment variable is not set.

• contractAddress: The address of the minting contract. Similar to proxyAddress, it is sourced from NEXT_PUBLIC_MINT_CONTRACT_ADDRESS or defaults to "test122212.mintspace2.testnet".

• network: Indicates the blockchain network we are interacting with. It defaults to "testnet" if NEXT_PUBLIC_NETWORK is not specified in the environment.

• callbackUrl: A URL used for callbacks, constructed dynamically based on the network variable. If we are on the testnet, it uses the testnet URL; otherwise, it defaults to the mainnet URL.

To customize these configurations for different environments, you can set the following environment variables in your .env file:

NOTE: the env variables need to have the NEXT_PUBLIC_ on the variable name due to be available for the browser to process

• NEXT_PUBLIC_PROXY_CONTRACT_ADDRESS: Your proxy contract address on Mintbase.
• NEXT_PUBLIC_MINT_CONTRACT_ADDRESS: Your mint contract address on Mintbase.
• NEXT_PUBLIC_NETWORK: The network you want to interact with ("testnet" or "mainnet").

after that you can run

pnpm install

and

pnpm dev

Extending

This project is setup 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 you think it would suit your needs.
