solana_kit_squads

Squads V4 multisig program client for the Solana Kit Dart SDK: instruction builders, account codecs, error helpers, and PDA derivations for the Squads V4 program (SQDS4ep65T869zMMBKyuUq6aD6EgTu8psMjkvj52pCf).

What you get

• Instruction builders for all 36 program instructions: multisig creation and member management, config and vault transactions, batches, proposals, spending limits, and transaction buffers
• Account codecs for multisig, vault transactions, config transactions, proposals, spending limits, and program config
• PDA derivations matching the upstream @sqds/multisig TypeScript SDK byte-for-byte: multisig, vault, transaction, proposal, batch, batch transaction, spending limit, ephemeral signer, and program config
• Error helpers for all 45 program errors
• Program parsing via parseSquadsMultisigInstruction

Installation

Install the package directly:

dependencies:
  "solana_kit_squads": ^

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

Derive the multisig and vault PDAs

Squads V4 PDA derivations match the upstream TypeScript SDK byte-for-byte, including vault indices and little-endian transaction indices.

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

Future<void> main() async {
  final (multisig, bump) = await findMultisigPda(
    createKey: Address('CreateKey11111111111111111111111111111111111'),
  );
  final (vault, vaultBump) = await findVaultPda(multisig: multisig, index: 0);

  print(multisig);
  print(vault);
}

Instruction builders cover multisig creation, config transactions, vault transactions, batches, proposals, and spending limits.

Key APIs

• findMultisigPda, findVaultPda, findTransactionPda, findProposalPda, findBatchTransactionPda, findSpendingLimitPda, findEphemeralSignerPda, findProgramConfigPda
• getMultisigCreateInstruction, getVaultTransactionCreateInstruction, getProposalCreateInstruction, and the rest of the generated builders
• parseSquadsMultisigInstruction, identifySquadsMultisigInstruction
• getSquadsMultisigErrorMessage, SquadsMultisigError

Reference

Generated with codama-renderers-dart from the Squads-Protocol / v4 Anchor IDL (sdk/multisig/idl/squads_multisig_program.json). PDA derivations and seed constants mirror the upstream TypeScript SDK and the Rust squads-client reference exactly, including little-endian u64 transaction indices and single-byte vault indices.
