func NewAdvanceNonceAccount ¶

func NewAdvanceNonceAccount(nonce, authority solana.PublicKey) solana.Instruction

NewAdvanceNonceAccount builds a System.AdvanceNonceAccount instruction that consumes the nonce and advances it to a new value. The nonce authority must sign the transaction.

func NewAllocate ¶

func NewAllocate(account solana.PublicKey, space uint64) solana.Instruction

NewAllocate builds a System.Allocate instruction that allocates space bytes for an account's data. The account must sign the transaction and must currently be a System-owned account with zero-length data.

func NewAssign ¶

func NewAssign(account, owner solana.PublicKey) solana.Instruction

NewAssign builds a System.Assign instruction that changes the owner program of an existing account. The account must currently be owned by the System program and must sign the transaction.

func NewAuthorizeNonceAccount ¶

func NewAuthorizeNonceAccount(nonce, authority, newAuthority solana.PublicKey) solana.Instruction

NewAuthorizeNonceAccount builds a System.AuthorizeNonceAccount instruction that changes the authority of a nonce account to newAuthority. The current authority must sign the transaction.

func NewCreateAccount ¶

func NewCreateAccount(from, newAccount solana.PublicKey, lamports, space uint64, owner solana.PublicKey) solana.Instruction

NewCreateAccount builds a System.CreateAccount instruction that funds newAccount with the given lamports, allocates space bytes for its data, and assigns its owner program. Both from and newAccount must sign the transaction.

func NewCreateAccountWithSeed ¶

func NewCreateAccountWithSeed(from, newAccount, base solana.PublicKey, seed string, lamports, space uint64, owner solana.PublicKey) solana.Instruction

NewCreateAccountWithSeed builds a System.CreateAccountWithSeed instruction that creates newAccount at the address derived from base, seed, and the owner program. Unlike CreateAccount, only the funding account (and base, when distinct) needs to sign — newAccount is derived and does not need its own keypair.

newAccount must equal CreateWithSeed(base, seed, owner) as computed by the Solana runtime.

func NewInitializeNonceAccount ¶

func NewInitializeNonceAccount(nonce, authority solana.PublicKey) solana.Instruction

NewInitializeNonceAccount builds a System.InitializeNonceAccount instruction that initializes a new nonce account with the given authority. The nonce account must already be funded and allocated by System.CreateAccount before calling this instruction.

func NewTransfer ¶

func NewTransfer(from, to solana.PublicKey, lamports uint64) solana.Instruction

NewTransfer builds a System.Transfer instruction that moves lamports from one account to another. The from account must sign the transaction. Both accounts are marked writable because their lamport balances change.

func NewTransferWithSeed ¶

func NewTransferWithSeed(from, base, to solana.PublicKey, lamports uint64, seed string, programID solana.PublicKey) solana.Instruction

NewTransferWithSeed builds a System.TransferWithSeed instruction that moves lamports from a seed-derived address to a destination. The base account must sign; no separate keypair for the from account is needed.

from must equal CreateWithSeed(base, seed, programID).

func NewWithdrawNonceAccount ¶

func NewWithdrawNonceAccount(nonce, authority, to solana.PublicKey, lamports uint64) solana.Instruction

NewWithdrawNonceAccount builds a System.WithdrawNonceAccount instruction that withdraws lamports from a nonce account to a destination. lamports must leave the nonce account with enough for rent-exemption, or withdraw all lamports to close it. The authority must sign the transaction.
