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 ?

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.


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

He's the dev for blockscan.com

Anybody know any tool for signing raw TX using Trezor?

Hello! This is Robert with FoldingCoin Inc.

If you haven’t heard it , myself and our lead dev James had a 3.5 hour interview on the Dogedcoindark radio show. You can find the embedded audio on our webpage http://foldingcoin.net/the-coin/

Rick the host over there is really interested in Counterparty and loves what we are all doing. He runs a 24/7 radio found here http://dogecoindark.net/radio/

He asked me to come back on the show to discus more about Counterparty in general. I suggested that we find some other Counterparty devs from various projects to come join in on the discussion and he enjoyed that idea. I was wondering if any of you would be interested in going on the show with me to discus how counterparty can help shape the future of digital assets and currency. It could be a long one, so prepare for a long show (the live casts are also at night beginning around 10pm EST). Rick gets some pretty good guests on there and i recommend you see who has gone on his show in the past https://www.mixcloud.com/dogedradio/

No time is set in stone yet, we are just trying to get a headcount of who is interested. You can email me [email protected] Thanks

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