Module system 

Hopper-native System Program CPI builders.

The API is Hopper-owned (builder pattern over AccountView / Address / Signer) and execution flows through Hopper’s checked native CPI semantics.

Provides the full System program surface: CreateAccount, Transfer, Assign, Allocate, the *WithSeed variants, and the durable-nonce family, plus a typed NonceState reader.

Modules

instructions

Legacy module-path re-exports.

Structs

Allocate

Builder for the system program’s Allocate instruction.

AllocateWithSeed

Builder for AllocateWithSeed.

Assign

Builder for the system program’s Assign instruction.

AssignWithSeed

Builder for AssignWithSeed.

AuthorizeNonceAccount

Builder for AuthorizeNonceAccount.

CreateAccount

Builder for the system program’s CreateAccount instruction.

CreateAccountAllowPrefund

Builder for the system program’s CreateAccountAllowPrefund instruction (tag 13).

CreateAccountWithSeed

Builder for CreateAccountWithSeed.

InitializeNonceAccount

Builder for InitializeNonceAccount.

NonceState

Typed, zero-copy view over an initialized durable-nonce account.

Transfer

Builder for the system program’s Transfer instruction.

TransferWithSeed

Builder for TransferWithSeed.

UpgradeNonceAccount

Builder for UpgradeNonceAccount.

WithdrawNonceAccount

Constants

MAX_SEED_LEN

Maximum byte length of a System-program seed string (Solana MAX_SEED_LEN). *WithSeed builders reject longer seeds.

NONCE_ACCOUNT_LEN

Minimum byte length of an initialized durable-nonce account.

NONCE_STATE_INITIALIZED

Nonce state tag for the initialized form.

NONCE_VERSION_CURRENT

Nonce account version tag for the current format.

RECENT_BLOCKHASHES_ID

Recent blockhashes sysvar address (SysvarRecentB1ockHashes...), required by the nonce instructions.

RENT_SYSVAR_ID

Rent sysvar address, required by some nonce instructions.

SYSTEM_PROGRAM_ID

System program address: 11111111111111111111111111111111
