makeSTXTokenTransfer

Constructs and signs a STX token transfer transaction. This is the primary function for sending STX from one address to another. For multi-sig transactions, all signer keys are provided and the transaction is signed automatically.

If you need to sign the transaction separately (e.g. with a hardware wallet), use makeUnsignedSTXTokenTransfer instead.

Usage

import { makeSTXTokenTransfer } from '@stacks/transactions';

const transaction = await makeSTXTokenTransfer({
  recipient: 'ST1SJ3DTE5DN7X54YDH5D64R3BCB6A2AG2ZQ8YPD5',
  amount: 1000000n, // in microSTX (1 STX = 1,000,000 microSTX)
  senderKey: 'b244296d5907de9864c0b0d51f98a13c52890be0404e83f273144004b81874603',
  memo: 'test transfer',
  network: 'testnet',
  fee: 200n,
  nonce: 0n,
});

const serializedTx = transaction.serialize();

Notes

• The amount is denominated in microSTX (1 STX = 1,000,000 microSTX).

• If fee is omitted, the fee is estimated automatically via the network.

• If nonce is omitted, the nonce is fetched automatically from the network.

• For multi-sig transfers, provide signerKeys, publicKeys, and numSignatures instead of senderKey.

• The memo field is optional and limited to 34 bytes.

Signature

function makeSTXTokenTransfer(
  txOptions: SignedTokenTransferOptions | SignedMultiSigTokenTransferOptions
): Promise<StacksTransactionWire>

Returns

Promise<StacksTransactionWire>

A promise that resolves to a signed StacksTransactionWire object, ready to be broadcast.

Parameters

txOptions (required)

• Type: SignedTokenTransferOptions | SignedMultiSigTokenTransferOptions

// Single-sig options
interface SignedTokenTransferOptions extends TokenTransferOptions {
  senderKey: PrivateKey;
}

// Multi-sig options
type SignedMultiSigTokenTransferOptions = TokenTransferOptions & {
  publicKeys: PublicKey[];
  numSignatures: number;
  signerKeys: PrivateKey[];
  address?: string;
};

// Shared base options
type TokenTransferOptions = {
  /** The recipient address (STX address or contract ID) */
  recipient: string | PrincipalCV;
  /** Amount to transfer in microSTX */
  amount: IntegerType;
  /** Optional memo string (max 34 bytes) */
  memo?: string;
  /** Post conditions for the transaction */
  postConditions?: PostCondition[];
  /** Post condition mode (Allow or Deny) */
  postConditionMode?: PostConditionMode;
  /** Whether the transaction is sponsored */
  sponsored?: boolean;
  /** Transaction fee in microSTX */
  fee?: IntegerType;
  /** Transaction nonce */
  nonce?: IntegerType;
} & NetworkClientParam;

For single-sig, provide senderKey. For multi-sig, provide publicKeys, numSignatures, and signerKeys.
