Mint To (Token)

You can mint some token for testing.

Token Program - Mint To Checked

tokenprog.MintToChecked(tokenprog.MintToCheckedParam{
	Mint:     mintPubkey,
	Auth:     alice.PublicKey,
	Signers:  []common.PublicKey{},
	To:       aliceTokenRandomTokenPubkey,
	Amount:   1e8,
	Decimals: 8,
}),

Mint is the mint you want to mint

To is the receiver

Auth is the mint owner, need to sign the tx.

Signers we pass empty first, I will take another chapter to discuss it

Amount the number you want to mint. It is the minimum number. If decimals is 8 and you want to mint 1, you will pass 1e8

Decimals the mint decimals

There is an instruction call MintTo You also can use it to mint token.
