Welcome to the Saturn V2 Integration Library!

Getting Started

First, we need to install the pnpm package manager.

Next, install all dependencies and run the development server:

pnpm i
pnpm run dev

Open http://localhost:3000 with your browser to see the result.

API Minting NFTs

Minting NFTs with our API is as simple as implementing the copy / pastable code in this library. This library has a demo that can be tested as well.

• Click on the "Mint NFTs" button in the Navbar.

• We need to get a preprod Saturn API key by following these steps:

1. Go to Preprod Saturn
2. Connect a preprod wallet (Nami is recommended you can switch to preprod in the settings).
3. Enter the studio and go to the "Settings Page" which is the gear icon on the left hand sidebar.
4. Click on the "Add API Key" button. Make sure to save this key as you will not be able to view it again (Note: the key in the image is revoked)

• After we have our API Key, paste it into the Saturn V2 Integration "Mint NFTs" page, connect your wallet, and press the "Mint NFT" button.
• This will have us execute 2 transactions, 1 to deploy the minting smart contract on the blockchain and 1 right after to mint the NFT.
• Note: when you mint your project, you only need to deploy the smart contract once and you can do so in the Saturn app. You do not need to deploy the contract on chain multiple times.

Here is the code for the 2 graphQL mutations required to Create an NFT Minting Transaction and to Submit an NFT Minting Transaction:

//---------------------------------------------------------------------------------------------------//
// Create and Submit NFT Transaction Functions
//---------------------------------------------------------------------------------------------------//
export const mutateCreateNFTMintBurnUpdateTransaction = async (input: CreateNFTMintBurnUpdateTransactionInput) => {
    const parameters = { input: input };
    v2GraphQLClient.setHeaders(await getGraphQLHeaders());
    const response: any = await v2GraphQLClient.request(
        gql`
            mutation CreateNFTMintBurnUpdateTransaction($input: CreateNFTMintBurnUpdateTransactionInput!) {
                createNFTMintBurnUpdateTransaction(input: $input) {
                    successTransactions {
                        transactionId
                        hexTransaction
                    }
                    error {
                        message
                    }
                }
            }
        `,
        parameters
    );
    const createNFTMintBurnUpdateTransactionPayload: CreateNFTMintBurnUpdateTransactionPayload =
        response?.createNFTMintBurnUpdateTransaction || {};
    return createNFTMintBurnUpdateTransactionPayload;
};

export const mutateSubmitNFTMintBurnUpdateTransaction = async (input: SubmitNFTMintBurnUpdateTransactionInput) => {
    const parameters = { input: input };
    v2GraphQLClient.setHeaders(await getGraphQLHeaders());
    const response: any = await v2GraphQLClient.request(
        gql`
            mutation SubmitNFTMintBurnUpdateTransaction($input: SubmitNFTMintBurnUpdateTransactionInput!) {
                submitNFTMintBurnUpdateTransaction(input: $input) {
                    transactionIds
                    error {
                        message
                    }
                }
            }
        `,
        parameters
    );
    const submitNFTMintBurnUpdateTransactionPayload: SubmitNFTMintBurnUpdateTransactionPayload =
        response?.submitNFTMintBurnUpdateTransaction || {};
    return submitNFTMintBurnUpdateTransactionPayload;
};
//---------------------------------------------------------------------------------------------------//

API Upgrading NFTs

After minting an NFT, now we want to upgrade the NFT. Make sure to check the console for the Saturn NFT Id that we just minted. Take that NFT Id along with the API Key and navigate to the Upgrade NFTs page.

Input the API Key as well as the NFT Id, click "Upgrade NFT" and you will be asked to sign an upgrade transaction! Congrats we have minted and upgraded an NFT!

The graphQL mutations that allow for minting the NFTs are the same for updating the NFTs to allow for composable transactions. This code is copy and pastable from the integration library so you can customize any type of minting logic you like.

You can even create complex gamification and crafting systems by combing Token Project and NFT Project transactions together with the APIs!
