setMnemonic

setMnemonic(words: string[]): Promise<boolean>

Sets the mnemonic phrase for the wallet.

This method allows you to restore a wallet from an existing mnemonic seed phrase. Use this when a user wants to import their wallet using a previously generated mnemonic.

Parameters

• words - An array of mnemonic words (typically 12 or 24 words) representing a valid BIP39 mnemonic phrase

Returns

boolean - Returns true if the mnemonic was set successfully.

Example

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

const director = new WalletDirector(new WasmWorkerTransport())

// Restore wallet from existing mnemonic
const existingMnemonic = [
  'word1',
  'word2',
  'word3',
  // ... remaining words
  'word12',
]

const success = await director.setMnemonic(existingMnemonic) 

if (success) {
  console.log('Mnemonic set successfully')
}
