validate static method

bool validate(List<String> mnemonic)

Validates a mnemonic phrase according to BIP-39 specification.

Returns true if the mnemonic is valid (correct length, valid words, valid checksum).

Implementation

static bool validate(List<String> mnemonic) {
  try {
    if (mnemonic.length % 3 != 0 ||
        mnemonic.length < 12 ||
        mnemonic.length > 24) {
      return false;
    }

    // Check if all words are in the wordlist
    for (final word in mnemonic) {
      if (!_englishWordlist.contains(word)) {
        return false;
      }
    }

    // Convert mnemonic to entropy and validate checksum
    final entropy = _mnemonicToEntropy(mnemonic);
    final regeneratedMnemonic = _entropyToMnemonic(entropy);

    return _listEquals(mnemonic, regeneratedMnemonic);
  } on Exception catch (_) {
    return false;
  }
}
