solana_kit_address_lookup_table 0.4.3

Address Lookup Table program client for the Solana Kit Dart SDK.

solana_kit_address_lookup_table

Address Lookup Table program client for the Solana Kit Dart SDK.

Provides instruction builders, codecs, account decoders, and parsers for the Address Lookup Table program, which manages lookup tables used in versioned (v0) transactions.

Installation

Installation

Install the package directly:

dependencies:
  "solana_kit_address_lookup_table": ^0.4.3

If your app uses several Solana Kit packages together, you can also depend on the umbrella package instead:

dart pub add solana_kit

Inside this monorepo, Dart workspace resolution uses the local package automatically.

How generated program clients work

Generated program clients share one API shape, so what you learn in one program transfers to the next:

• Program address constant — a ...ProgramAddress constant identifies the program on-chain.
• Identification helpers — identify...Program and identify...Instruction match programs and instructions without string comparisons.
• Instruction builders and parsers — get...Instruction encodes parameters, parse...Instruction decodes a transaction instruction back into typed arguments.
• Account codecs — get...AccountCodec and decode...Account turn on-chain bytes into typed account objects.
• Plan helpers — get...InstructionPlan helpers compose multi-instruction flows (such as creating an account before acting on it) into transaction plans the standard executor can run.

Errors thrown by these helpers and by transaction execution surface as SolanaError; match program-specific failures with the program error helpers.

Match program errors from your program

Transaction failures surface as SolanaError values. When a transaction fails with a custom program error, the RPC response identifies the failing instruction by index — pair it with the transaction message to attribute the error to a program and match custom error codes.

import 'package:solana_kit_addresses/solana_kit_addresses.dart';
import 'package:solana_kit_programs/solana_kit_programs.dart';

Future<void> handleTransactionFailure(Object error) async {
  const myProgramAddress = Address('11111111111111111111111111111111');
  final transactionMessage = TransactionMessageInput(
    instructions: {0: InstructionInput(programAddress: myProgramAddress)},
  );

  if (isProgramError(error, transactionMessage, myProgramAddress, 42)) {
    // Custom program error code 42 from this program.
  } else if (isProgramError(error, transactionMessage, myProgramAddress)) {
    // Any other custom error from this program.
  }
}

transactionMessage is a lightweight TransactionMessageInput — a map from instruction index to InstructionInput(programAddress: ...). Build it from the same instructions you sent, so matching stays accurate even when the transaction mixes instructions from several programs.

Usage

import 'package:solana_kit_address_lookup_table/solana_kit_address_lookup_table.dart';
import 'package:solana_kit_addresses/solana_kit_addresses.dart';

void main() {
  const tableAddress = Address('11111111111111111111111111111111');
  const authority = Address('11111111111111111111111111111112');
  const payer = Address('11111111111111111111111111111113');
  const recipient = Address('11111111111111111111111111111114');
  const addr1 = Address('11111111111111111111111111111115');
  const addr2 = Address('11111111111111111111111111111116');

  // Create a new address lookup table.
  final createIx = getCreateLookupTableInstruction(
    programAddress: addressLookupTableProgramAddress,
    address: tableAddress,
    authority: authority,
    payer: payer,
    systemProgram: systemProgramAddress,
    recentSlot: BigInt.from(1000),
    bump: 255,
  );

  // Extend a lookup table with new addresses.
  final extendIx = getExtendLookupTableInstruction(
    programAddress: addressLookupTableProgramAddress,
    address: tableAddress,
    authority: authority,
    payer: payer,
    systemProgram: systemProgramAddress,
    addresses: [addr1, addr2],
  );

  // Deactivate a lookup table.
  final deactivateIx = getDeactivateLookupTableInstruction(
    programAddress: addressLookupTableProgramAddress,
    address: tableAddress,
    authority: authority,
  );

  // Close a deactivated lookup table.
  final closeIx = getCloseLookupTableInstruction(
    programAddress: addressLookupTableProgramAddress,
    address: tableAddress,
    authority: authority,
    recipient: recipient,
  );

  print(createIx.programAddress);
  print(extendIx.programAddress);
  print(deactivateIx.programAddress);
  print(closeIx.programAddress);
}

Instructions

Instruction	Discriminator	Description
CreateLookupTable	0	Create a new address lookup table.
FreezeLookupTable	1	Freeze a lookup table, preventing further modifications.
ExtendLookupTable	2	Extend a lookup table with additional addresses.
DeactivateLookupTable	3	Deactivate a lookup table before closing.
CloseLookupTable	4	Close a deactivated lookup table and reclaim lamports.

Account

The AddressLookupTableAccountData decoder can decode on-chain account data for lookup tables, including the authority, deactivation slot, and stored addresses.
