This guide will help you create your first smart account using the Squads API. For a complete overview of the API capabilities, see the API Introduction.

​
Prerequisites

Before you begin, make sure you have:

​
Making API Requests

All requests should be made to the base URL: https://developer-api.squads.so Include your API key and network in the request headers of every request: 
Authorization: Bearer YOUR_API_KEY
x-squad-network: devnet // or 'mainnet' for production

​
Create your first smart account

Create a basic smart account with a single signer. For more details about smart account creation and management, see the Create Smart Account documentation. 
const response = await fetch(
  "https://developer-api.squads.so/api/v0/smart_account/transaction/create",
  {
    method: "POST",
    headers: {
      Authorization: "Bearer YOUR_API_KEY",
      "x-squad-network": "devnet",
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      smart_account_signers: [
        {
          address: "YOUR_WALLET_ADDRESS",
          permissions: ["CAN_INITIATE", "CAN_VOTE", "CAN_EXECUTE"],
        },
      ],
      threshold: 1,
    }),
  }
);

const { smart_account_address } = await response.json();
console.log(`Smart Account created: ${smart_account_address}`);
That’s it! Your smart account is ready to use immediately. No transaction submission or fee payment required. You can later add more signers or set up spending limits as needed.

​
Create a token transfer

Let’s create a token transfer transaction using your new smart account. We’ll break this down into steps:

​
1. Set up the transfer instruction

First, import the required dependencies and create the token transfer instruction: 
import { createTransferInstruction } from "@solana/spl-token";
import { 
  Connection, 
  PublicKey, 
  TransactionMessage, 
  VersionedTransaction 
} from "@solana/web3.js";

// Initialize connection to Solana
const connection = new Connection("https://api.devnet.solana.com");

// Create the token transfer instruction
const transferInstruction = createTransferInstruction(
  new PublicKey("SOURCE_TOKEN_ACCOUNT"),    // The smart account's token account
  new PublicKey("DESTINATION_TOKEN_ACCOUNT"),
  new PublicKey(smart_account_address),     // The smart account is the authority
  1000000n                                  // Amount (e.g., 1 USDC)
);

​
2. Create a versioned transaction

Next, create a V0 transaction message with the latest blockhash: 
// Get the latest blockhash
const latestBlockhash = await connection.getLatestBlockhash();

// Create a V0 transaction message
const message = new TransactionMessage({
  payerKey: new PublicKey(smart_account_address),
  recentBlockhash: latestBlockhash.blockhash,
  instructions: [transferInstruction]
}).compileToV0Message();

// Create and serialize the transaction
const transaction = new VersionedTransaction(message);
const serializedTransaction = Buffer.from(
  transaction.serialize()
).toString('base64');

​
3. Prepare the transaction

Send the transaction to the Squads API for preparation. This step will:
  • Add the necessary program instructions
  • Configure fee payment
  • Return the prepared transaction and fee details
const prepareResponse = await fetch(
  "https://developer-api.squads.so/api/v0/smart_account/transaction/prepare",
  {
    method: "POST",
    headers: {
      Authorization: "Bearer YOUR_API_KEY",
      "x-squad-network": "devnet",
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      smart_account_address,
      transaction: serializedTransaction,
      transaction_signers: ["YOUR_WALLET_ADDRESS"],
      fee_config: {
        currency: "usdc",        // Choose 'usdc' or 'sol'
        payer_address: "YOUR_FEE_PAYER_ADDRESS",
      },
    }),
  }
);

// Get the prepared transaction and fee information
const { transaction: preparedTransaction, fee } = await prepareResponse.json();

// Log the fee details
console.log(
  `Transaction prepared! Fee: ${fee.amount_decimal} ${fee.currency.toUpperCase()}`
);
console.log(
  `Fee in SOL: ${fee.sol_equivalent.amount_decimal} SOL`
);

​
4. Sign and submit the transaction

Finally, sign the prepared transaction with your wallet and submit it to Solana: 
// Decode the prepared transaction
const decodedTransaction = VersionedTransaction.deserialize(
  Buffer.from(preparedTransaction, "base64")
);

// Sign with your wallet
decodedTransaction.sign([wallet]);

// Submit to Solana
const signature = await connection.sendRawTransaction(
  decodedTransaction.serialize()
);
console.log(`Transaction sent: ${signature}`);

// Wait for confirmation
const confirmation = await connection.confirmTransaction({
  signature,
  blockhash: latestBlockhash.blockhash,
  lastValidBlockHeight: latestBlockhash.lastValidBlockHeight
});
console.log("Transfer complete!");
Each step builds on the previous one to create a complete token transfer flow. The Squads API handles the complexity of smart account execution, allowing you to focus on building your application logic.
