Key instead seed phrase

[ubuntutest]

Greetings,
i am developing my first DAPP, i am using ethers.

I would like to have an information, is it possible to use the secret key instead of the words?

the code is simply the following:

mnemonic = "xxx xxx xxx ..."
const provider = new ethers.providers.WebSocketProvider('wss://.....')
const wallet = ethers.Wallet.fromMnemonic(mnemonic);
const account = wallet.connect(provider);

i would like to use key instead

key = "0ab134csd..............."
const provider = new ethers.providers.WebSocketProvider('wss://.....')
const wallet = ethers.Wallet.fromMnemonic(key);
const account = wallet.connect(provider);

@ubuntutest You can use the Wallet class by passing in the private key in the constructor.

const privateKey = '....';
const wallet = new ethers.Wallet(privateKey);

Just adding a note, you should use a private key that is generated from a great entropy source. The ethers.Wallet.createRandom() uses the secure entropy sources available in the enviornment. If the current environment does not have a secure entropy source, an error is thrown.

(also moving to discussions)

const privateKey = '....';
const wallet = new ethers.Wallet(privateKey);

Thanks, it was simple, it worked without problems.

Not sure about the ethers.Wallet.createRandom() function, why should I use it if it already works correctly, and how the randomly generated value can work and know my wallet?

Could you give me a simple example for what I need?
Thanks again

If you already have a private key, you do not need to use this code. This is only in case you want to create a new.

const wallet = ethers.Wallet.createRandom()
wallet.privateKey // newly generated private key

sure, I use one of a metamask wallet.

Thanks again
