[ESHOP launched] Trezor: Bitcoin hardware wallet

@ Trezor team: Why are the transaction fees fixed when using mytrezor?

Fiddling with tx fees is an advanced feature and does not belong to myTREZOR which is aimed for regular folks.

any guide & sources how to flash trezor with the snake game you guys cooked up during the hackathlon?
will you release it with official signatures so that the bootloader won't warn about unofficial firmware?
future plans for gaming on trezor?

not sure I'll ask our devs.

When I see how many people get excited for the snake
I'm wondering whether we are so childish or so old

Couldn't a feature be implemented into Trezor that allows of making custom transactions? Ex. send from a certain address, use x fee amount. It could just be a quick switch on the main page. For example, in the top right corner there could be a drop-down that would allow selecting of either basic, or advanced mode.

I understand your point but our goal is to make bitcoin secure AND EASY FOR EVERYONE.

Everything could be added but our goal is to keep the bitcoin experience seamless while maintaining highest level of security. Once we add this kind of features the less experienced user will start wondering why his tx didnt go through etc.
This is our goal for myTrezor, not Trezor.
There are other more advanced wallets that can implement Trezor support to the full scale of their options. there is demand so I hope they will soon.

I think having the following warning on the seed card (bolded in red on the same side as the list) would really help reduce phishing attacks (hacked trezor email list for example) and people who are tricked into typing out their seed at fake sites or corrupt software:

Entering the seed words on a computer MUST be done in a random order as picked by the TREZOR hardware to prevent theft. Never allow the computer software (even official looking TREZOR software) to pick the word number and NEVER reveal to the computer what word number you are entering. Using the seed in sequence and/or without a TREZOR weakens the security of the seed and is recommended for experts only.


I think that warning is very important. The only way to get the private keys from a TREZOR are to trick the person into revealing it!!!

No spyware or phishing attempt could get the seed if the user followed that ONE rule! I don't think it would be obvious to most that entering the seed in sequence would be bad.


I also think it would be useful to mention on the front on the card that if a copy is needed for a will or protection from natural disasters that the only safe method to copy it is to write it out by hand.

yeah... and coin age/transaction size logic needs to be added...

had 100 coins at an address for months but mytrezer still forced a fee i think 1 or two confirmations and bitcoin-qt no longer requires a fee to transfer the same and it is picked up within a block or two as its high priority even fee free

oh, oh, another one.
could you do pong.mytrezor.com and use two trezors as control pads?

as to your wonder, I'd go with old(er) and childish in the evenings

edit: as for the feasibility using trezor as control pad, I'm using it with a long cable so usability is not an issue

[Hawkix]

!!! THIS !!! 

[spin]

I can't operate my trezor with chrome on win64 or on ubuntu.  How do I get round this?
EDIT: Found the very well hidden bridge software and got it working.  Perhaps a FAQ entry for this?

[irritant]

and you can win some satoshis to make it interesting?

that would turn me off. pong is in that category of games that would be indecent to play for money. 
feels like training your puppy to steel neighbors' newspaper so that I don't have to buy them. 

the goal of pong is to add support of multiple (concurrent) trezors to lokal pc. it could lead to some special type of multisig support. imagine you have a set of married wallets and you wait for a third signer to arrive, what will you do? why not play pong?

My first post

We really need some kind of counterparty wallet which supports offline signing with a TREZOR or something.

I believe there's a bounty for this. Just surprised why still nobody claims for it. With the Trezor API, it is not so difficult to add this function. Actually, for personal usage, it is possible to develop a super lightweight wallet to support 'send' function at least. The idea is like this:

1: Check the balance by using Blockscan API (it is safe to skip this step if you are sure you have enough balance in your address. But I don't think BlockScan will mind if we use their API, since it is not so different with we just querying the balance in their website. Correct me if I am wrong, Mtbitcoin. :-) )
2: Generate the 'send' transaction with the help of counterparty lib (coding it follows the specification in other language is also easy. Recommend to use the OP_RETURN version if you don't mind maybe a little bit longer confirmation time).
3: Sign the transaction with Trezor API.
4: broadcast the transaction in https://blockchain.info/pushtx.

This client does not need any bitcoin full node and even counterpartyd running. I just don't have time to implement by myself. If anyone is interested, feel free to implement it to get the bounty.


Moreover, I think if Mtbitcoin can implement this in Blockscan, it will be even better. All these can be written in Python and Javascript. Due to the feature of Trezor, nobody needs to worry about leaking the private key when using this function.


 

I don't think it should be too difficult but I have not looked at the Trezor API. Does it support offline raw transaction signing ?

The counterparty Dev team is working hard on the desktop client, so once that goes out it resolve most of the "client" issues.
 

Anybody know any tool for signing raw TX using Trezor?

Hmm, maybe electrum can do this.

I use python-trezor for this.  You have to write a small python program, as the example program cmdtr.py does not support signing transactions.  If you use the Python API you have to supply the inputs and outputs of the raw transaction manually.

Code:

devices = HidTransport.enumerate()
transport = HidTransport(devices[0])
client = TrezorClient(transport)
client.set_tx_api(TXAPIBitcoin())
(signatures, serialized_tx) = client.sign_tx('Bitcoin', [proto_types.TxInputType(address_n=client.expand_path("44'/0'/0'/0/1"), prev_hash=binascii.unhexlify("6cd0..."), prev_index=0)], [proto_types.TxOutputType(amount=100000, script_type=proto_types.PAYTOADDRESS, address="12dR...")])
print binascii.hexlify(serialized_tx)

Look into cmdtr.py/Helloworld.py for examples that use python-trezor.

Thanks! I am not a programmer but I understood Python as it is like a human readable language. I will post this in counterparty thread. If anybody know any other, feel free to post in counterparty.

FYI there is a bounty going there for creating one. Link : https://github.com/CounterpartyXCP/counterwallet/issues/2.

Feature Request: Space Invaders !!!

Now that Encompass Multi-coins BIP44 Electrum wallet is out (https://github.com/mazaclub/encompass).  When can we see multi-coins support for Trezor also?

Trezor already supports 5 coins https://github.com/trezor/trezor-mcu/blob/40efefc5716366618accc2e4871fdb7a6d92d15f/firmware/coins.c

The Trezor wallets are showing weird transaction amounts in the wallets this morning.

On some of the small transactions, I have deposit amounts showing up as  "1e-8.00"   anyone else experiencing this?

Wait, clarification...this seems to be only on the weird spam deposits that sometimes show up in my wallet...

[DevonMiner]

I'm trying to make a payment from my Trezor, the PIN is accepted, by my passphrase is not. Odd, as I made a payment a few days ago, but I can't remember whether I had to enter my passphrase on that occasion.

Checked the help pages, but can't see anything to assist me.

Is it possible to reset a passphrase? Any ideas/advice welcome.

Thanks,

Devon

I'd try forgetting your device on mytrezor, clearing browser cash and trying again.

I don't believe pass phrase should be required for sending, just on connection, pin for sending...
