Core Technologies and Their Integration

Solana Kit: Modern Solana Development

Solana Kit represents the next generation of Solana development tools, the key advantages of Solana Kit include:

Type-Safe RPC Interactions: Every RPC call is fully typed with Solana RPC method coverage, catching errors at compile time rather than runtime. This includes reading/writing blockchain data, transaction simulation, and real-time subscriptions.

Unified Transaction Handling: Solana Kit provides a consistent interface for both transaction building and confirmation, including compute budget estimation for reliable blockchain operations.

Web Crypto API: By leveraging native browser and Node.js crypto primitives, Solana Kit keeps applications lightweight while maintaining security and performance. This approach provides native runtime security without external dependencies.

Squads v4: Advanced Multisig Capabilities

Squads v4 supports programmable permissions with granular access control, configurable time locks and comprehensive proposal lifecycle management with detailed status tracking.

Permission System: Squads uses a bitmask system for permissions, allowing granular control over member capabilities:

1 = PROPOSE (can create new transaction proposals)

2 = VOTE (can approve/reject existing proposals)

4 = EXECUTE (can execute approved transactions)

7 = ALL (combination of all permissions)

Proposal Lifecycle: Proposals are configured with thresholds and time locks providing additional security layers and follow a structured lifecycle from: Draft → Active → Approved/Rejected → Executed/Cancelled

Codama: Automated Client Generation

Codama automatically generates type-safe clients from Anchor program IDLs, eliminating the need for manual instruction building. This is particularly valuable when working with complex programs like Squads that have numerous instruction variants.

Building the Multisig System

Step 1: Multisig Initialization

The initialization process sets up a controlled multisig with proper permissions and funding. Let's examine how this works:

const multisigConfig = {
  threshold: 2, // 2-of-3 approval required
  timeLock: 0, // No delay before execution
  createKey: await createSignerFromKeyPair(ephemeralKeypair),// Ephemeral key for PDA derivation (must be unique and used only once)
  creator: await createSignerFromKeyPair(manager), // Creator/fee payer of the multisig account
  configAuthority: address(managerAddress), // Enables direct config changes
  rentCollector: address(managerAddress), // Account that receives reclaimed rent from closed accounts (null = creator receives rent)
  members: [
    {
      key: managerAddress,
      permissions: { mask: 7 }, // Full permissions
    },
    {
      key: voter1Address,
      permissions: { mask: 2 }, // Vote only
    },
    {
      key: voter2Address,
      permissions: { mask: 2 }, // Vote only
    }
  ]
};

This configuration creates a 2-of-3 multisig where the manager has full control, while the two voters can only approve or reject proposals. The configAuthority field enables direct configuration changes without requiring voting, which is useful for admin tasks.

The initialization process handles several critical tasks:

Transaction Building: Uses Codama-generated instructions with Solana Kit's transaction utilities:

// Prepare the instruction with codama generated utils
const multisigCreateInstruction = getMultisigCreateV2Instruction(multisigConfig);

// Send and confirm transaction using centralized signer system
const signature = await signAndSendTransaction(
  [multisigCreateInstruction],
  [manager, ephemeralKeypair], // signers
  managerAddress // feePayer
);

Keypair Generation: Creates keypairs for all participants using Web Crypto API primitives.

Security Warning: The extractable: true parameter and file-based storage are used here for development simplicity. (More info)

const keypair = await crypto.subtle.generateKey(
  'Ed25519',
  true, // extractable = true to allow exporting private key
  ['sign', 'verify']
);

Devnet Funding: Automatically requests SOL airdrops and provides guidance for USDC funding through Circle's faucet.

const LAMPORTS_PER_SOL = 1_000_000_000;
const airdropAmount = BigInt(2 * LAMPORTS_PER_SOL)); // 2 SOL from faucet
const signature = await rpc.requestAirdrop(address(manager), lamports(airdropAmount).send();

Vault Setup: Deposits initial funds into the multisig vault and distributes SOL to voters for transaction fees.

// Get vault PDA (index 0)
const [vaultPda] = await getVaultPda(multisigPda, 0);
// Create SOL transfer instruction to vault
const transferAmount = BigInt(0.01 * LAMPORTS_PER_SOL); // 0.01 SOL in lamports
const sender = await loadWalletFromConfig('manager');
const signer = await createSignerFromKeyPair(sender);
const transferIxns = await transferInstruction(signer, transferAmount, SOL_MINT, vaultPda);

// Get the address from the CryptoKey to use it as a feePayer, then sign it, send and confirm the signed transaction
const proposerAddress = await getAddressFromPublicKey(proposer.publicKey);
const signature = await signAndSendTransaction(
  transferIxns,
  [sender],
  senderAddress
);

Step 2: Creating Payment Proposals

The proposal system demonstrates one of the most interesting aspects of this integration: combining Squads SDK with Solana Kit. Due to serialization complexities with Codama-generated utilities, the Squads SDK is used for vault transaction instruction creation, converting the result to Solana Kit data structure format. Here's how the proposal creation works:

const proposerAddress = await getAddressFromPublicKey(proposer.publicKey);
const vaultTransaction = multisig.instructions.vaultTransactionCreate({
  multisigPda: new PublicKey(multisigPda),
  transactionIndex: newTransactionIndex,
  creator: new PublicKey(proposerAddress),
  vaultIndex: 0,
  ephemeralSigners: 0,
  transactionMessage: new TransactionMessage({
    payerKey: new PublicKey(proposerAddress),
    recentBlockhash: (await solanaConnection.getLatestBlockhash()).blockhash,
    instructions: instructions,
  }),
  memo: Payment of ${amount} ${paymentType} to ${recipientAddress},
});
// Convert to Solana Kit format
const vaultInstruction = fromLegacyTransactionInstruction(vaultTransaction);

const signature = await signAndSendTransaction(
  [vaultInstruction],
  [proposer],
  proposerAddress
);

This pattern demonstrates how to bridge different Solana libraries while maintaining type safety and consistency. The fromLegacyTransactionInstruction function from @solana/compat handles the conversion, allowing backwards compatibility.

Step 3: The Voting Process

Voting on a proposed transaction requires loading multisig data, validating member permissions, and following the standard transaction pattern: prepare, sign, send, and confirm.

const approveInstruction = getProposalApproveInstruction({
  multisig: address(multisigPda),
  proposal: address(proposalPda),
  member: await createSignerFromKeyPair(voter),
  args: {
    memo: Approved by selected signer,
  },
});

const signature = await signAndSendTransaction(
  [approveInstruction],
  [voter],
  voterAddress
);

Step 4: Transaction Execution

The execution phase is the final step in the multisig process, where approved transactions are submitted to the Solana network. This requires careful validation to ensure the transaction has received sufficient approvals and the executor has the necessary permissions. The execution process follows the same pattern as other operations - prepare, sign, and submit to the network:

const executeInstructionResult = await multisig.instructions.vaultTransactionExecute({
  connection: solanaConnection,
  multisigPda: new PublicKey(multisigPda),
  transactionIndex: transactionIndex,
  member: new PublicKey(executorAddress),
});
const vaultInstruction = fromLegacyTransactionInstruction(executeInstructionResult.instruction);
const signature = await signAndSendTransaction(
  [vaultInstruction],
  [executor],
  executorAddress
);

Advanced Features and Management

Configuration Management

Squads supports two types of multisig configurations: controlled and non-controlled. Controlled multisigs allow direct configuration changes without voting, while non-controlled multisigs require the full proposal lifecycle for any changes.

For controlled multisigs, configuration changes are straightforward:

const memberArgs: MemberArgs = {
  key: address(newMemberAddress),
  permissions: { mask: permissions }
};
const instruction = getMultisigAddMemberInstruction({
  multisig: address(multisigPda),
  configAuthority: await createSignerFromKeyPair(configAuthority),
  rentPayer: await createSignerFromKeyPair(configAuthority),
  systemProgram: SYSTEM_PROGRAM_ADDRESS,
  newMember: memberArgs,
  memo: memo || null
});
const signature = await signAndSendTransaction(
  [instruction],
  [configAuthority],
  configAuthorityAddress
);

For non-controlled multisigs, configuration changes would require a Config Transaction instead, this follows the same lifecycle as the payment proposal: Propose → Approve → Execute, ensuring democratic governance of the multisig itself.

Information Dashboard

The information system provides comprehensive visibility into multisig operations, real-time vault balances, member analysis, and complete transaction history, making it easy to monitor multisig health and activity:

const transactions = await Promise.all(
  Array.from({ length: lastTransactionIndex }, (_, i) => 
    fetchTransactionInfo(multisigAddress, i + 1)
  )
);
const activeTransactions = transactions.filter(tx => tx.status === 'Active' && !tx.isStale);
const approvedTransactions = transactions.filter(tx => tx.status === 'Approved' && !tx.isStale);
const executedTransactions = transactions.filter(tx => tx.status === 'Executed');

Stale Proposal Management

The system includes stale proposal detection and cleanup to recover rent:

// Identify transactions that can be safely closed to recover rent
async function getClosableTransactions(multisigAddress: string) {
  const multisigAccount = await fetchMultisig(rpc, address(multisigAddress));
  const closableTransactions = [];

  // Iterate through all transactions in the multisig
  for (let i = 1; i <= Number(multisigAccount.data.transactionIndex); i++) {
    const [transactionPda] = await getVaultTransactionPda(multisigAddress, BigInt(i));
    const [proposalPda] = await getProposalPda(multisigAddress, BigInt(i));
    // Fetch both vault transaction and proposal data in parallel
    const [vaultTransactionResult, proposalResult] = await Promise.allSettled([
      fetchMaybeVaultTransaction(rpc, address(transactionPda)),
      fetchMaybeProposal(rpc, address(proposalPda))
    ]);
    const vaultTransaction = vaultTransactionResult.status === 'fulfilled' ? vaultTransactionResult.value : null;
    const proposal = proposalResult.status === 'fulfilled' ? proposalResult.value : null;
    // Skip if vault transaction doesn't exist
    if (!vaultTransaction || !vaultTransaction.exists) continue;
    
    const isStale = i <= Number(multisigAccount.data.staleTransactionIndex || 0);
    let status = 'Unknown';
    if (proposal && proposal.exists) {
      status = proposal.data.status.__kind;
      // Can close if: stale, cancelled, executed, or rejected
      if (isStale || status === 'Cancelled' || status === 'Executed' || status === 'Rejected') {
        closableTransactions.push({
          index: i,
          pda: transactionPda,
          proposalPda: proposalPda,
          status: status,
        });
      }
    }
  }

  return closableTransactions;
}

// Execute cleanup for all closable transactions
const closableTransactions = await getClosableTransactions(multisigAddress);
for (const tx of closableTransactions) {
  const closeInstruction = getVaultTransactionAccountsCloseInstruction({
    multisig: address(multisigAddress),
    proposal: address(tx.proposalPda),
    transaction: address(tx.pda),
    rentCollector: address(signerAddress),
  });

  const cleanerAddress = await getAddressFromPublicKey(cleaner.publicKey);
  const signature = await signAndSendTransaction(
    [closeInstruction],
    [cleaner],
    cleanerAddress
  );
}

Core Solana Kit Usage

The system uses several utility modules that work together to handle Solana blockchain operations. These utilities manage RPC connections, transaction preparation, signing, simulation, error handling, send and confirmation.

RPC and Connection Management (`rpc.ts`)

This module creates connections to the Solana blockchain using both modern and legacy APIs. This approach ensures compatibility with the latest Solana Kit while supporting existing libraries like the Squads SDK with the web3js rpc connection.

// Create RPC client using @solana/kit
export const rpc = createSolanaRpc(RPC_URL);
export const rpcSubscriptions = createSolanaRpcSubscriptions(RPC_URL.replace('http', 'ws'));
export const sendAndConfirmTransaction = sendAndConfirmTransactionFactory({ rpc, rpcSubscriptions });

// Legacy web3.js connection for Squads SDK compatibility
export const solanaConnection = new web3.Connection(RPC_URL, 'confirmed');

The createSolanaRpc function creates a type-safe RPC client that validates all blockchain operations at compile time. This helps catch errors before the code runs.

The rpcSubscriptions client enables real-time monitoring by converting the HTTP URL to WebSocket. This lets the app listen for account changes and transaction confirmations as they happen.

The sendAndConfirmTransactionFactory returns a function that you can call to send a blockhash-based transaction to the network and to wait until it has been confirmed.

Transaction Preparation (`prepare.ts`)

This module builds Solana transactions by combining instructions with proper compute budget instructions estimate and error handling on the simulation.

export async function prepareTransaction(
  instructions: Instruction<string>[],
  feePayer: string,
) {
  const { value: latestBlockhash } = await rpc.getLatestBlockhash().send();
  const finalInstructions = await getComputeBudget(
    instructions,
    feePayer,
    {},
    latestBlockhash
  );
  // Build transaction message with proper structure
  const message = pipe(
    createTransactionMessage({ version: 0 }),
    tx => setTransactionMessageFeePayer(payer, tx),
    tx => setTransactionMessageLifetimeUsingBlockhash(latestBlockhash, tx),
    tx => appendTransactionMessageInstructions(finalInstructions, tx),
  );
  return compileTransaction({ ...message, lifetimeConstraint: latestBlockhash });
}

The function starts by getting the latest blockhash, which acts as a timestamp and prevents transaction replay attacks. Transactions expire after a certain number of blocks.

The getComputeBudget function estimates how much compute power the transaction needs by simulating it. It also calculates the right priority fee based on current network conditions to ensure the transaction gets processed successfully.

The transaction is built using a functional approach with the pipe function. Each step adds a specific part: the fee payer, lifetime constraint, and instructions.

Compute Budget Management (`compute.ts`)

This module calculates the right amount of compute power and fees needed for each transaction to ensure it gets processed successfully.

async function simulateAndGetBudget(
  instructions: Instruction<string>[],
  feePayer: string,
  lookupTableAccounts: AddressesByLookupTableAddress,
  latestBlockhash: Readonly<{
    blockhash: Blockhash;
    lastValidBlockHeight: bigint;
  }>,
  priorityLevel: PriorityLevel
): Promise<[Instruction<string>, Instruction<string>]> {
  const payer = address(feePayer);
  const finalInstructions = [
    getSetComputeUnitLimitInstruction({
      units: DEFAULT_COMPUTE_UNITS,
    }),
    getSetComputeUnitPriceInstruction({
      microLamports: DEFAULT_PRIORITY_FEE,
    }),
    ...instructions,
  ];
  const message = pipe(
    createTransactionMessage({ version: 0 }),
    (tx) => setTransactionMessageFeePayer(payer, tx),
    (tx) => setTransactionMessageLifetimeUsingBlockhash(latestBlockhash, tx),
    (tx) => appendTransactionMessageInstructions(finalInstructions, tx)
  );

  const messageWithLookupTables =
    compressTransactionMessageUsingAddressLookupTables(
      message,
      lookupTableAccounts
    );

  const compiledMessage = compileTransaction(messageWithLookupTables);
  const wireTransaction = getBase64EncodedWireTransaction(compiledMessage);
  const [computeUnits, priorityFee] = await Promise.all([
    getComputeUnits(wireTransaction),
    getPriorityFeeEstimate(wireTransaction, {
      priorityLevel,
      lookbackSlots: 150,
      includeVote: false,
      evaluateEmptySlotAsZero: true,
    }),
  ]);

  const computeBudgetIx = getSetComputeUnitLimitInstruction({
    units: Math.ceil(computeUnits * 1.1),
  });

  const priorityFeeIx = getSetComputeUnitPriceInstruction({
    microLamports: priorityFee,
  });

  return [computeBudgetIx, priorityFeeIx];
}

The function starts by creating a transaction with default compute settings. It then simulates the transaction to determine how much compute power it actually needs and what priority fee to pay.

The simulation runs in parallel to get both the compute units and priority fee estimate at the same time. This makes it faster than running them one after another.

The function adds a 10% buffer to the compute units (Math.ceil(computeUnits * 1.1)) to ensure the transaction doesn't fail due to slight variations in execution.

#### Supporting Functions

The transaction simulation is executed without signature verification (since it's not signed yet) to get an accurate estimate of compute usage. It checks for common errors like insufficient funds and provides clear error messages to users.

async function getComputeUnits(
  wireTransaction: Base64EncodedWireTransaction
): Promise<number> {
  const simulation = await rpc
    .simulateTransaction(wireTransaction, {
      sigVerify: false,
      encoding: 'base64',
    })
    .send();

  if (simulation.value.err && simulation.value.logs) {
    // Extract specific error message from program logs
    const errorMessage = extractErrorMessage(simulation.value.logs);
    if (errorMessage) throw new Error(errorMessage);
    
    // If no specific error was found, throw generic simulation error
    throw new Error('Transaction simulation error');
  }

  return Number(simulation.value.unitsConsumed) || DEFAULT_COMPUTE_UNITS;
}

Transaction simulation logs are parsed and converted into clear, actionable messages that users can understand and act on.

function extractErrorMessage(logs: string[]): string | null {
  for (const log of logs) {
    // Look for Squads program error format: "Error Code: ErrorName. Error Number: XXXX. Error Message: ErrorMessage"
    const errorMatch = log.match(/Error Code: (\w+)\. Error Number: \d+\. Error Message: (.+)/);
    if (errorMatch && errorMatch[1]) {
      return errorMatch[1]; // Return just the error name (e.g., "AlreadyApproved")
    }
    
    // Look for other common error patterns
    if (log.includes('InvalidLockupAmount')) return 'Invalid staked amount: Should be > 1';
    if (log.includes('0x1771') || log.includes('0x178c')) return 'Maximum slippage reached';
    if (log.includes('Error: insufficient funds')) return 'Insufficient USDC balance for this transaction';
    if (
      log.includes('Program 11111111111111111111111111111111 failed: custom program error: 0x1') ||
      log.includes('insufficient lamports')
    ) {
      return 'You need more SOL to pay for transaction fees';
    }
  }
  return null;
}

Transfer Utilities (`transfer.ts`)

This module handles both SOL and SPL token transfers with ATA existence check and creation if needed.

export async function transferInstruction(
  signer: TransactionSigner,
  amount: bigint,
  mint: Address,
  destination: Address
): Promise<Instruction<string>[]> {
  if (mint === 'So11111111111111111111111111111111111111112') {
    // SOL transfer
    return [getTransferSolInstruction({
      source: signer,
      destination: destination,
      amount,
    })];
  } else {
    // SPL token transfer with ATA creation
    const [tokenAccount] = await findAssociatedTokenPda({
      mint, owner: address(signer.address), tokenProgram: TOKEN_PROGRAM_ADDRESS,
    });
    
    const [destinationTokenAccount] = await findAssociatedTokenPda({
      mint, owner: destination, tokenProgram: TOKEN_PROGRAM_ADDRESS,
    });

    const instructions = [];
    // Check if destination ATA exists and create if needed
    const accountExists = await rpc.getAccountInfo(destinationTokenAccount, { encoding: 'base64' }).send();
    if (!accountExists.value) {
      instructions.push(getCreateAssociatedTokenInstruction({
        mint, owner: destination, tokenProgram: TOKEN_PROGRAM_ADDRESS,
        payer: signer, ata: destinationTokenAccount,
      }));
    }

    instructions.push(getTransferInstruction({
      source: tokenAccount, destination: destinationTokenAccount,
      authority: signer, amount,
    }));

    return instructions;
  }
}

The function first checks if the transfer is for SOL (native Solana token) or an SPL token. SOL transfers are simple - just one instruction to move lamports between accounts.

For SPL tokens, it's more complex. The function:

Calculates the associated token account (ATA) addresses for both source and destination

Checks if the destination ATA exists

Creates the ATA if it doesn't exist

Adds the transfer instruction

Transaction Signing (`sign.ts`)

This module handles the complete process of signing and sending transactions to the blockchain.

export async function signAndSendTransaction(
  instructions: Instruction<string>[],
  signers: CryptoKeyPair[],
  feePayer: string,
  commitment: 'processed' | 'confirmed' | 'finalized' = 'confirmed'
): Promise<string> {  
  // Prepare transaction with compute budget
  const transactionMessage = await prepareTransaction(instructions, feePayer);
  
  // Sign the transaction message
  const signedTransaction = await signTransaction(signers, transactionMessage);
  assertIsSendableTransaction(signedTransaction);

  // Send and confirm using the factory
  await sendAndConfirmTransaction(signedTransaction, { commitment });
  
  return getSignatureFromTransaction(signedTransaction);
}

The function uses the prepare module to build the transaction, then signs it with the provided signers. It validates the transaction before sending and uses the RPC factory to listen on transaction signature confirmation.

The function returns the transaction signature, from the signed transaction, which can be used to track the transaction on blockchain explorers.
