What is Mycelium?¶
Mycelium is a mobile Bitcoin wallet for Android and iOS, although TREZOR is curently supported only on Android device.
TREZOR User Manual¶
Before you can start using Mycelium with your TREZOR, make sure you have an OTG cable for connecting TREZOR to your phone or tablet. Using TREZOR with Mycelium is pretty straighforward.
Importing account from TREZOR¶
To import a TREZOR account into Mycelium, go to Accounts tab, select Add New Account (key icon) > Advanced > TREZOR. Now, connect your TREZOR via OTG cable and confirm the access. Enter your TREZOR PIN (and also passphrase, if you have previously enabled passphrase feature) and wait until Mycelium loads all your TREZOR accounts.
Note that PIN is required only once per TREZOR connection session.
Select TREZOR account the list to import it into Mycelium, give it a name and wait until Mycelium synchronizes all the transactions and balance. If you need to import more accounts, repeat the steps above. To import a new empty TREZOR account, select Import next unused account below TREZOR account list.
Without TREZOR device connected, imported accounts work in watch-only mode. You can check total balance, transaction history and display next unsused receiving address, but you cannot send any transaction.
Sending transaction from imported account¶
To send transaction from TREZOR account you need to connect your TREZOR. Select Send from Balance tab and enter recipient address and amount. Hit the Send button, check the transaction on TREZOR screen and confirm it.
Sending transaction from TREZOR directly¶
You can also send transaction directly from TREZOR using Mycelium without importing it first. Simply connect your TREZOR and select Cold Storage from app menu and choose TREZOR. After Mycelium loads your TREZOR accounts, select the one you want to spend from, enter recipient address and amount and finalize the transaction by checking and confirming it on TREZOR.
Importing watch-only accounts from TREZOR Wallet¶
If you want to use Mycelium as a watch-only wallet for your TREZOR, you can import accounts directly from TREZOR Wallet without connecting the device.
In TREZOR Wallet, click on the name of your TREZOR and in Basic settings, click on Show XPUBs. Select account you want to import into Mycelium to reveal QR code with account public key.
In Mycelium, go to Accounts tab, select Add New Account (key icon) > Advanced > Scan and scan QR code from TREZOR Wallet to import the account. Give it a name and wait until Mycelium synchronizes it.
After that, you will be able to check balance, transaction history and display next unsused receiving address.
