Solana: get NFT supply cap?

Question

How can I be sure a token will not be minted anymore?

In this tutorial we can see a maxSupply specified. How do I retrieve this value give a mint address?

  await actions.mintNFT({
    connection,
    wallet: new NodeWallet(keypair),
    uri: 'https://34c7ef24f4v2aejh75xhxy5z6ars4xv47gpsdrei6fiowptk2nqq.arweave.net/3wXyF1wvK6ARJ_9ue-O58CMuXrz5nyHEiPFQ6z5q02E',
    maxSupply: 1
  });

Answer 1

I believe the next step would be the following ->

await setAuthority(
  connection,
  fromWallet,            // Payer of the transaction fees
  mint,                  // Account 
  fromWallet.publicKey,  // Current authority 
  0,                     // Authority type: "0" represents Mint Tokens 
  null                   // Setting the new Authority to null
);

The setAuthority function will revoke minting privileges and ensure that you can not create additional tokens of this type. Note that this action cannot be undone.
