public final class SystemProgram

Instructions of the System Program. Amounts are lamports, 10^9 to the SOL, and are written as unsigned 64-bit values.

Fields

public static final long LAMPORTS_PER_SOL = 1000000000L Lamports in one SOL.

`public static` `Instruction transfer(SolanaAddress from, SolanaAddress to, long lamports)`	Moves lamports between two system accounts; `from` signs.
`public static` `Instruction createAccount(SolanaAddress payer, SolanaAddress newAccount, long lamports, long space, SolanaAddress owner)`	Creates an account owned by a program, funded with `lamports` and sized `space` bytes; both the payer and the new account sign.
`public static` `Instruction assign(SolanaAddress account, SolanaAddress owner)`	Assigns an account to a program.
`public static` `Instruction allocate(SolanaAddress account, long space)`	Allocates space in an account.
`public static` `Instruction advanceNonceAccount(SolanaAddress nonceAccount, SolanaAddress authority)`	Advances a durable nonce.

public static final long LAMPORTS_PER_SOL = 1000000000L

Lamports in one SOL.

public static Instruction transfer(SolanaAddress from, SolanaAddress to, long lamports)

Moves lamports between two system accounts; from signs.

public static Instruction createAccount(SolanaAddress payer, SolanaAddress newAccount, long lamports, long space, SolanaAddress owner)

Creates an account owned by a program, funded with lamports and sized space bytes; both the payer and the new account sign.

public static Instruction assign(SolanaAddress account, SolanaAddress owner)

Assigns an account to a program.

public static Instruction allocate(SolanaAddress account, long space)

Allocates space in an account.

public static Instruction advanceNonceAccount(SolanaAddress nonceAccount, SolanaAddress authority)

Advances a durable nonce. It must be the first instruction of a transaction whose recent blockhash is the nonce value.
