Eidoo app v2 does not support Litecoin natively.
Eidoo Legacy used the standard derivation path for the LTC wallet. Because of this, you will be able to use your 12 words to restore your LTC wallet directly in other wallets that supports it.
In case you need to retrieve your Litecoin private key, please follow these steps:
- connect to the site https://iancoleman.io/bip39/ (this site can also be used in offline mode)
- in the Mnemonic section type the 12 words in the BIP39 Mnemonic field and set the Coin field to LTC-Litecoin
- check that the Derivation Path is set to BIP44
If all the data is correct you will find the master key in the section "Account Extended Private Key".
