hasMnemonicSet

hasMnemonicSet(): Promise<boolean>

Checks if a mnemonic phrase has been set for the wallet.

This method allows you to determine whether a mnemonic seed phrase has been previously configured. It's useful for conditional logic in wallet initialization flows, such as deciding whether to generate a new mnemonic or prompt the user to import an existing one.

Returns

boolean - Returns true if a mnemonic has been set, false otherwise.

Example

import { WalletDirector } from '@fedimint/core'
import { WasmWorkerTransport } from '@fedimint/transport-web'

const director = new WalletDirector(new WasmWorkerTransport())

// Check if a mnemonic has been set
const hasMnemonic = await director.hasMnemonicSet() 

if (!hasMnemonic) {
  // Generate a new mnemonic if none exists
  const mnemonic = await director.generateMnemonic()
  console.log('Generated new mnemonic:', mnemonic)
} else {
  // Retrieve the existing mnemonic
  const existingMnemonic = await director.getMnemonic()
  console.log('Existing mnemonic found')
}
