Functions

func AdvanceNonce

func AdvanceNonce(nonce, authority ed25519.PublicKey) solana.Instruction

Reference: https://github.com/solana-labs/solana/blob/f02a78d8fff2dd7297dc6ce6eb5a68a3002f5359/sdk/src/system_instruction.rs#L113-L119

func AuthorizeNonce

func AuthorizeNonce(nonce ed25519.PublicKey) solana.Instruction

AuthorizeNonce returns an instruction to change the entity authorized to execute nonce instructions on the account

The `Pubkey` parameter identifies the entity to authorize

func CreateAccount

func CreateAccount(funder, address, owner ed25519.PublicKey, lamports, size uint64) solana.Instruction

Reference: https://github.com/solana-labs/solana/blob/f02a78d8fff2dd7297dc6ce6eb5a68a3002f5359/sdk/src/system_instruction.rs#L58-L72

func DecompileInitializeNonce

func DecompileInitializeNonce()

func DecompileWithdrawNonce

func DecompileWithdrawNonce()

func GetNonceValueFromAccount

func GetNonceValueFromAccount(info solana.AccountInfo) (val solana.Blockhash, err error)

GetNonceValueFromAccount returns the nonce value of a nonce account.

func InitializeNonce

func InitializeNonce(nonce, auth ed25519.PublicKey) solana.Instruction

InitializeNonce returns an instruction to change the state of an Uninitalized nonce account to Initialized, setting the nonce value

The `Pubkey` parameter specifies the entity authorized to execute nonce instruction on the account

No signatures are required to execute this instruction, enabling derived nonce account addresses

Reference: https://github.com/solana-labs/solana/blob/f02a78d8fff2dd7297dc6ce6eb5a68a3002f5359/sdk/src/system_instruction.rs#L146

func WithdrawNonce

func WithdrawNonce(nonce, auth, receipient ed25519.PublicKey, lamports uint64) solana.Instruction

WithdrawNonce returns an instruction to withdraw funds from a nonce account

The `uint64` parameter is the lamports to withdraw, which must leave the account balance above the rent exempt reserve or at zero.

Reference: https://github.com/solana-labs/solana/blob/f02a78d8fff2dd7297dc6ce6eb5a68a3002f5359/sdk/src/system_instruction.rs#L131
