solana_kit_memo 0.4.2

Memo program client for the Solana Kit Dart SDK.

solana_kit_memo

Memo program client for the Solana Kit Dart SDK.

Provides generated codecs and ergonomic helpers for the Memo program, which attaches arbitrary UTF-8 memo text to Solana transactions.

Installation

Installation

Install the package directly:

dependencies:
  "solana_kit_memo": ^0.4.2

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.

Usage

import 'package:solana_kit_address_constants/solana_kit_address_constants.dart';
import 'package:solana_kit_memo/solana_kit_memo.dart';

void main() {
  final instruction = getAddMemoInstruction(
    programAddress: memoProgramAddress,
    memo: 'Hello from Solana Kit',
  );

  print(instruction.programAddress);
}

Use memoLegacyProgramAddress when you need to target the legacy Memo program:

import 'package:solana_kit_address_constants/solana_kit_address_constants.dart';
import 'package:solana_kit_memo/solana_kit_memo.dart';

void main() {
  final legacyInstruction = getAddMemoInstruction(
    programAddress: memoLegacyProgramAddress,
    memo: 'legacy memo',
  );

  print(legacyInstruction.programAddress);
}

Key APIs

• getAddMemoInstruction({required String memo}) — builds a Memo instruction from plain Dart text.
• AddMemoInstructionData — generated instruction data model.
• getAddMemoInstructionDataCodec() — UTF-8 codec for AddMemo data.
• memoProgramAddress — current Memo program address.
• memoLegacyProgramAddress — legacy Memo program address.
