Bitcoin Forum

I want to ask for those people who already tried using their Android phones only.
If in my acount on Trezor and I have multiple addresess with available bitcoin.

Example:
Address A: 0.04 btc
Address B: 0.02 btc
Address C: 0.01 btc

So if I just want to spend the btc on Address C and I will spend not more than on the available balance of Address C, example 0.005 btc only.

How can I do it? ? Since I can't do it on the it on https://beta-wallet.trezor.io .
Any solution to this or maybe a trusted android app wallet that can I import my trezor account?

I use mycelium and i see option "Sign with Trezor/KeepKey" on there. As far as i know, mycelium is pretty trusted wallet, but just in case you maybe want to try do more research about this, in case there's a problem or something with mycelium that i don't know.

Have you tried there the one I explained on my example?
Because if we do it on electrum desktop wallet and import my trezor wallet, it works.  That's why I am looking for that kind of Bitcoin wallet.

Nah, i never try that. However, since you mention electrum how about try electrum wallet for android? Maybe it has same feature as electrum on dekstop wallet.

The mobile version of Electrum has limited functionality. It doesn't even support hardware wallets. Mycelium (https://play.google.com/store/apps/details?id=com.mycelium.wallet&hl=pl) supports hardware wallets and allows users to list Unspent Outputs. @GreatArkansas, you should be able to spend specific coins using this feature.

Oh, I haven't heard mycelium can do it, I already tried mycelium but only for viewing the balance of my wallet but never tried to send to someone using mycelium wallet.
Thank you BitCryptex, I will try it.

And if I import my wallet into Mycelium through a trezor, will the wallet developers not get my private keys, can I somehow get them from the trezor using third-party software like this wallet?

Mycelium will act as a watch-only wallet. You will still have to connect your Trezor to sign transactions. Your private keys won't be exposed. You should be able to obtain your Master Private Key from the seed if you ever need it.

No.

Your private keys never leave the device. You can not access them in any way (except for vulnerability which might exist, but are not known yet).
A hardware wallet keeps your private keys secured and only uses them to sign transactions/messages. The signing process is completely done within the device.

It just has one interface which accepts unsigned (or partially signed) transactions and gives back a signed one.

Hi, update about this. When I used yesterday the mycelium to try if I can spend specific on particular address, I can't do it.
I imported my trezor to android app of mycelium, all I can do is to see only those addresses with Unspent Outputs , with amount in BTC and it can redirect me to block explorer , I can't use and spend on particular address.

What do you mean by importing Trezor's wallet? Did you remove your Trezor device or using XPUB.
I think you are trying to spend transactions through a watch-ony wallet. For more check ----> https://wiki.trezor.io/Apps-Mycelium.

I already done that, what I want to do is to spend only particular address that has btc balance on my wallet, check my example on the first post.
I already selected a trezor account then inside that account I have multiple address that has btc balance, so what I want to do is select only a particular address where I can spend remaining BTC, just like my example in the first post.

It looks like this feature is not supported by Mycelium, sorry. I don't think if there is any other Android Bitcoin wallet with hardware wallet support and coin control. Samourai Wallet (https://samouraiwallet.com/features) has a basic coin control but it doesn't support hardware wallets. The only way to do that right now, is pairing your wallet with Electrum on a PC.
