A very secure way to store your MOBI after receiving them is on a Ledger Nano S (if you are advanced you can setup multi-sig and more but that is beyond this guide) [no Trezor does not currently support Stellar or Mobius — please ask them to!]. Ledger only recently implemented Stellar support so many Stellar wallets do not support it yet. The advanced Stellar Laboratory however does and it can be used to configure your Nano S to receive MOBI and be used to send MOBI.

Below are the steps to setup your Ledger Nano S to receive MOBI:

A. Initialize your Ledger Nano S for Stellar

4. Copy your Stellar public key — this is your Ledger Nano S Stellar public key.

B. Configure your Ledger Nano S to accept MOBI

i. Using https://mystellar.tools/ (easy)

Go to https://mystellar.tools/ and click “Sign in with Ledger”

2. Click “SIGN IN” on the popup dialog.

3. Under TOOLS on the left select “Manage trustlines”

4. Under “Anchor’s domain” enter mobius.network and click the magnifying glass

5. MOBI will show up — click it, then click the ADD button.

6. The transaction will flash on your Nano S — confirm it says Add Trust and MOBI then press the right (checkmark) button.

7. You should see the below — congrats your Nano S can now accept MOBI!

ii. Using the Stellar Laboratory (hard)

Go to the Stellar Laboratory Transaction Builder.

2. For Source Account enter your Ledger Nano S Stellar public key from above.

3. Click the “Fetch next sequence…” button.

Under Asset select Alphanumeric 4, Asset Code = MOBI, and Issuer Account ID = GA6HCMBLTZS5VYYBCATRBRZ3BZJMAFUDKYYF6AH6MVCMGWMRDNSWJPIH

5. Scroll down and click “Sign in Transaction Signer”.

6. On the next page click “Sign with Default BIP Path”.
