Typescript encountered an error while attempting to generate an AptosAccount due to an authentication key issue (INVALID

Question

Typescript encountered an error while attempting to generate an AptosAccount due to an authentication key issue (INVALID

Currently, my goal is to establish a token collection through the use of the Aptos Typescript SDK.

const account = new AptosAccount(Uint8Array.from(Buffer.from(PRIVATE_KEY)), ACCOUNT_ADDR);

await tokenClient.createCollection(
        account,
        "A test collection 1",
        "A test collection",
        "https://google.com",
    );

However, I am encountering the following error:

ApiError2: {"message":"Invalid transaction: Type: Validation Code: INVALID_AUTH_KEY","error_code":"vm_error","vm_error_code":2}

I am unsure of what mistake I may be making. Any insights on this issue?

I attempted to follow the official Aptos example but with a twist - rather than creating a new account, I intend to utilize an existing account with funds already allocated.

If you possess a private key in the form of a hexadecimal string, the following code snippet demonstrates how you can handle it:

import { AptosAccount, HexString } from "aptos";

const privateKeyHex = "0x57f6046ff85febd0da6d4e5ef4e2f1b7f9c78f1619f8b40ecf738fad65afcd0";
const privateKeyBytes = HexString.ensure(privateKeyHex).toUint8Array();
const account = new AptosAccount(privateKeyBytes);

After encountering the same issue, I discovered that the root cause was a mismatch between the address and private key. It turns out that my private_key was not in the correct ed25519 format.

To resolve this problem, make sure your keys are generated using the ed25519 curve. You can create your address from the key by using a library like bip_utils. In my case, I used bip_utils to generate a bip_private_key (compatible with Near protocol, which also uses ed25519) and then converted it as follows:

private_key = ed25519.PrivateKey.from_hex(bip_private_key)

In addition to Daniel's answer, I wanted to provide more information on how to retrieve the private key after creating a wallet and then using it:

import { AptosAccount } from "aptos";

const wallet = new AptosAccount();
const privateKeyHex = wallet.toPrivateKeyObject().privateKeyHex;

// ...

const privateKeyBytes = HexString.ensure(privateKeyHex).toUint8Array();
const account = new AptosAccount(privateKeyBytes);

Learn how to implement this using TS SDK v2:

// To start, you'll need to generate a private key instance for either the Ed25519 or Secp256k1 scheme.
const privateKeyEd = new Ed25519PrivateKey("0xdcaf65ead38f7cf0eb4f81961f8fc7f9b7f1e2f45e2d4a6da0dbef85f46f6057");
// Alternatively, use the Secp256k1 scheme
const privateKeySec = new Secp256k1PrivateKey("0xdcaf65ead38f7cf0eb4f81961f8fc7f9b7f1e2f45e2d4a6da0dbef85f46f6057");

// Next, create an account. Keep in mind that this method is only applicable to accounts with unchanged authentication keys.
const account = await Account.fromPrivateKey({ privateKey });
