Monero (XMR) was designed to use a different type of mnemonic phrase to backup wallets. This means any 24word Coinomi phrase is not directly compatible to import to XMR specific wallets such as the CakeWalet or Monerujo. There is a way to convert your 24word phrase into the 25 word XMR seed following the steps below.
Please CAREFULLY follow these steps and handle your recovery phrase as securely as possible:
1- open https://coinomi.github.io/tools/bip39/
2- Turn your device offline for greater security
3- Enter your Coinomi recovery phrase on the first text box of the page (BIP39 mnemonic)
4- Select "XMR" from the coin list
5- Scroll down to 'derived addresses' and check that you see your XMR receive address on the first position of the list (Read important notes below if you have multiple XMR wallets)
6- If your address shows correctly, scroll up and you will see a box labeled "XMR Seed Words",Copy those 25 words down ON PAPER!
7- Close the page and turn your device online
8- Download and install Cake wallet/Monerujo from your device app store
9- Select "Restore Wallet - Restore from seed/keys - Monero"
10- Enter the 25 words on the text box labeled "Enter your seed phrase"
11- Below the seed, make sure the "legacy" option is selected, then continue.
12- Set the restore date to a few days before the first transaction you ever received into that wallet. If you don't remember, choose blockheight 1, then click Restore.
13- Check that your address in Cake Wallet is the same as in Coinomi. If they match, simply wait for the synchronization to finalize (it can take several hours) and your balance and transactions will show. If the addresses don't match, you made some mistake. It's safe to start the process over until everything is correct.
Important Notes:
- If the first address on the list of step 5 doesn't match your Coinomi's XMR receive address, you made some mistake when entering your Recovery Phrase, or you received into a secondary wallet (se below). Double check that you're entering the correct Phrase from Coinomi's "Settings - Manage wallets" screen, and if the wallet you're restoring is using a BIP39 passphrase or not. A BIP39 passphrase should be entered on the "BIP39 Passphrase (optional)" text box of the page.
- Coinomi allows you to make more than one wallet for each coin. If you are trying to find the address for a secondary wallet you created, tap+hold that wallet in Coinomi and select "... / Account details". Note its derivation path. The numeric values for "purpose", "coin" and "account" on the page must match the numeric values of the derivation path in Coinomi.
