solana_kit_system 0.4.1

System Program instruction builders for the Solana Kit Dart SDK.

solana_kit_system

Generated Dart client for the Solana System Program, part of the Solana Kit Dart SDK.

Provides typed instruction builders, account decoders, error definitions, PDA helpers, and program address constants for all 13 System Program instructions. Generated from the upstream Codama IDL at solana-program/system (js@v0.12.0).

Installation

dependencies:
  solana_kit_system: ^0.3.2

Usage

import 'package:solana_kit_system/solana_kit_system.dart';

// Create a new account
final ix = getCreateAccountInstruction(
  programAddress: systemProgramAddress,
  fromPubkey: payer,
  newAccountPubkey: newAccount,
  lamports: BigInt.from(10000000),
  space: BigInt.from(165),
  owner: tokenProgramAddress,
);

// Transfer SOL
final transferIx = getTransferSolInstruction(
  programAddress: systemProgramAddress,
  source: payer,
  destination: recipient,
  amount: BigInt.from(1000000),
);

// Derive a system account PDA
final pda = findCreateAccountWithSeedPda(
  base: baseAddress,
  seed: 'my-seed',
  owner: systemProgramAddress,
);

Instructions

Instruction	Discriminator	Description
CreateAccount	0	Create a new account with the given space and owner.
Assign	1	Assign an account to a program.
TransferSol	2	Transfer lamports between accounts.
CreateAccountWithSeed	3	Create an account derived from a base address and seed.
AdvanceNonceAccount	4	Advance the nonce value in a nonce account.
WithdrawNonceAccount	5	Withdraw lamports from a nonce account.
InitializeNonceAccount	6	Initialize a nonce account with an authority.
AuthorizeNonceAccount	7	Change the authority of a nonce account.
Allocate	8	Allocate space for an account.
AllocateWithSeed	9	Allocate space using a derived seed.
AssignWithSeed	10	Assign an account to a program using a derived seed.
TransferSolWithSeed	11	Transfer lamports using a derived source address.
UpgradeNonceAccount	12	Upgrade a nonce account to a versioned format.

Accounts

• Nonce — Nonce account data including authority, nonce value, and fee calculator.

Types

• NonceState — Enum for nonce account state (uninitialized, initialized, ready).
• NonceVersion — Enum for nonce account version (legacy, current).

Errors

Nine typed error codes covering invalid nonce state, missing accounts, insufficient funds, and other System Program failure modes.
