mintTo static method

TransactionInstruction mintTo({ required Pubkey mint, required Pubkey account, required Pubkey mintAuthority, List<Pubkey> signers = const [], required bu64 amount, })

Mints new tokens to an account. The native mint does not support minting.

Keys:

Single authority

• [w] mint - The mint.
• [w] account - The account to mint tokens to.
• [s] mintAuthority - The mint's minting authority.

Multisignature authority

• [w] mint - The mint.
• [w] account - The account to mint tokens to.
• [] mintAuthority - The mint's multisignature mint-tokens authority.
• [s] signers - The signer accounts.

Data:

• amount - The amount of new tokens to mint.
