Mint To Instruction

Creates new tokens and deposits them into a specified account. Only the mint authority can perform this operation.

Before we can mint any token, we'll need to already have:

Initialized a Mint account which we hold the mintAuthority
Initialized a Token account or Associated Token account where we're going to mint tokens to

The amount of tokens we mint are "normalized" for decimals. This means that if we want to mint 1 token that has 6 decimals, we'll need to actually put 1e6 as amount

Raw Instruction

By using just "raw" instruction without any abstraction, this is how minting a token would look like:

const destination = Keypair.generate();
 
const tokenAccount = await getAssociatedTokenAddress(
    mint.publicKey,
    destination.publicKey,
);
 
// Create ATA creation instruction
const createAtaInstruction = createAssociatedTokenAccountIdempotentInstruction(
    keypair.publicKey, // payer
    tokenAccount, // associated token account address
    destination.publicKey, // owner
    mint.publicKey, // mint
);
 
// Mint tokens to ATA 
const mintToInstruction = createMintToInstruction(
    mint.publicKey, // mint
    tokenAccount, // destination
    keypair.publicKey, // mint authority
    1_000e6, // amount of tokens
);
 
const transaction = new Transaction().add(
    createAtaInstruction,
    mintToInstruction,
);
 
const signature = await sendAndConfirmTransaction(connection, transaction, [keypair]);
 
console.log(`Token accounts created and tokens minted! Check out your TX here: https://explorer.solana.com/tx/${signature}?cluster=devnet`);

Abstracted Instruction

This is how the same instructions would look like abstracted away with the mintTo() instruction:

const destination = Keypair.generate();
 
const ata = await getOrCreateAssociatedTokenAccount(
    connection,
    keypair,
    mint,
    destination.publicKey
);
 
console.log(`This is your ATA: ${ata.address}!`)
  
let tx = await mintTo(
    connection,
    keypair,
    mint,
    ata.address,
    keypair.publicKey,
    1e6,
);
 
console.log(`Succesfully Minted!. Transaction Here: https://explorer.solana.com/tx/${tx}?cluster=devnet`)
