Class TokenProgram

java.lang.Object

com.codename1.crypto.solana.TokenProgram

public final class TokenProgram
extends Object

Instructions of the SPL Token program and the Associated Token Account program. Token amounts are raw base units, unsigned 64-bit; a mint's decimals says where the point is. Each builder has a form that takes the token program, for mints under Token-2022.

Method Summary

Modifier and Type	Method	Description
static Instruction	closeAccount(SolanaAddress account, SolanaAddress destination, SolanaAddress owner)	CloseAccount: closes an empty token account and returns its rent to destination.
static Instruction	createAssociatedTokenAccount(SolanaAddress payer, SolanaAddress wallet, SolanaAddress mint, boolean idempotent)	Creates the associated token account of wallet for mint, paid by payer.
static Instruction	createAssociatedTokenAccount(SolanaAddress payer, SolanaAddress wallet, SolanaAddress mint, SolanaAddress tokenProgram, boolean idempotent)	Creates an associated token account under a given token program.
static Instruction	transfer(SolanaAddress source, SolanaAddress destination, SolanaAddress owner, long amount)	Transfer: moves tokens between two token accounts; owner signs.
static Instruction	transferChecked(SolanaAddress source, SolanaAddress mint, SolanaAddress destination, SolanaAddress owner, long amount, int decimals)	TransferChecked: a transfer that also names the mint and its decimals, which wallets prefer and Token-2022 requires.
static Instruction	transferChecked(SolanaAddress tokenProgram, SolanaAddress source, SolanaAddress mint, SolanaAddress destination, SolanaAddress owner, long amount, int decimals)	TransferChecked under a given token program.

Method Details

transfer

public static Instruction transfer(SolanaAddress source,
 SolanaAddress destination,
 SolanaAddress owner,
 long amount)

Transfer: moves tokens between two token accounts; owner signs.

transferChecked

public static Instruction transferChecked(SolanaAddress source,
 SolanaAddress mint,
 SolanaAddress destination,
 SolanaAddress owner,
 long amount,
 int decimals)

TransferChecked: a transfer that also names the mint and its decimals, which wallets prefer and Token-2022 requires.

transferChecked

public static Instruction transferChecked(SolanaAddress tokenProgram,
 SolanaAddress source,
 SolanaAddress mint,
 SolanaAddress destination,
 SolanaAddress owner,
 long amount,
 int decimals)

TransferChecked under a given token program.

closeAccount

public static Instruction closeAccount(SolanaAddress account,
 SolanaAddress destination,
 SolanaAddress owner)

CloseAccount: closes an empty token account and returns its rent to destination.

createAssociatedTokenAccount

public static Instruction createAssociatedTokenAccount(SolanaAddress payer,
 SolanaAddress wallet,
 SolanaAddress mint,
 boolean idempotent)

Creates the associated token account of wallet for mint, paid by payer. The idempotent form succeeds when the account already exists, which is what a sender wants before a first transfer to a recipient.

createAssociatedTokenAccount

public static Instruction createAssociatedTokenAccount(SolanaAddress payer,
 SolanaAddress wallet,
 SolanaAddress mint,
 SolanaAddress tokenProgram,
 boolean idempotent)

Creates an associated token account under a given token program.
