Function signTransaction

  • signTransaction<TTransaction>(keyPairs, transaction): Promise<FullySignedTransaction & TTransaction>

  • Given an array of CryptoKey objects which are private keys pertaining to addresses that are required to sign a transaction, this method will return a new signed transaction of type FullySignedTransaction.

    This function will throw unless the resulting transaction is fully signed.

    Type Parameters

    • TTransaction extends Readonly<{
          messageBytes: TransactionMessageBytes;
          signatures: SignaturesMap;
      }>

    Parameters

    Returns Promise<FullySignedTransaction & TTransaction>

    Example

    import { generateKeyPair } from '@solana/keys';
    import { signTransaction } from '@solana/transactions';

    const signedTransaction = await signTransaction([myPrivateKey], tx);

    See

    partiallySignTransaction if you want to sign the transaction without asserting that the resulting transaction is fully signed.
