buildTransferTokensTransaction

Call Signature

function buildTransferTokensTransaction<TVersion, TFeePayer>(args): Promise<{
  feePayer: Readonly<{
     address: Address<TAddress>;
  }>;
  instructions: readonly Instruction<string, readonly (AccountLookupMeta<string, string> | AccountMeta<string>)[]>[];
  version: TVersion;
}>;

Create a transaction that can transfer tokens to the desired wallet/owner, including creating their ATA if it does not exist

The transaction has the following defaults:

  • Default version = legacy
  • Default computeUnitLimit = 31_000

Example

const destination = address(...);

const transferTokensTx = await buildTransferTokensTransaction({
  feePayer: signer,
  latestBlockhash,
  mint,
  authority: signer,
  amount: 900, // note: be sure to consider the mint's `decimals` value
  // if decimals=2 => this will transfer 9.00 tokens
  // if decimals=4 => this will transfer 0.090 tokens
  destination,
  // use the correct token program for the `mint`
  tokenProgram, // default=TOKEN_PROGRAM_ADDRESS
  // default cu limit set to be optimized, but can be overridden here
  // computeUnitLimit?: number,
  // obtain from your favorite priority fee api
  // computeUnitPrice?: number, // no default set
});

Type Parameters

Type ParameterDefault type
TVersion extends TransactionVersion"legacy"
TFeePayer extends TransactionSignerTransactionSigner

Parameters

ParameterType
args{ computeUnitLimit?: number | bigint; computeUnitPrice?: number | bigint; latestBlockhash?: undefined; version?: TVersion; } & { amount: number | bigint; authority: Address | TransactionSigner; destination: Address | TransactionSigner; destinationAta?: Address; feePayer: Address | TransactionSigner; mint: Address | KeyPairSigner; sourceAta?: Address; tokenProgram?: Address; }

Returns

Promise<{ feePayer: Readonly<{ address: Address<TAddress>; }>; instructions: readonly Instruction<string, readonly (AccountLookupMeta<string, string> | AccountMeta<string>)[]>[]; version: TVersion; }>

Remarks

  • transferring without creating the ata is generally < 10_000cu
  • validating the ata onchain during creation results in a ~15000cu fluctuation
