Function: createSignerFromKeyPair()

function createSignerFromKeyPair(
  keyPair
): Promise<KeyPairSigner<string>>;

Creates a KeyPairSigner from a provided CryptoKeyPair.

The MessagePartialSigner#signMessages | signMessages and TransactionPartialSigner#signTransactions | signTransactions functions of the returned signer will use the private key of the provided key pair to sign messages and transactions.

Note that both the MessagePartialSigner#signMessages | signMessages and TransactionPartialSigner#signTransactions | signTransactions implementations are parallelized, meaning that they will sign all provided messages and transactions in parallel.

Parameters

Parameter	Type
keyPair	CryptoKeyPair

Returns

Promise<KeyPairSigner<string>>

Example

import { generateKeyPair } from '@solana/keys';
import { createSignerFromKeyPair, KeyPairSigner } from '@solana/signers';

const keyPair: CryptoKeyPair = await generateKeyPair();
const signer: KeyPairSigner = await createSignerFromKeyPair(keyPair);
