Hi all,

It seems to me that the exchange functionality on the Trezor applications (the rich client beta, and the web app) is new and incomplete.

I was able to exchange bitcoin to USD Tether (ERC20) which is done through the bitcoin wallet on the web app and it showed up on the Etherium wallet as a Tether ERC20 token... all good.

But there does not appear to be anyway to use the exchange function from the Etherium wallet side to exchange back to bitcoin.

Does anyone have experience with this?

It appears that the exchange functionality that does exist on the web app is not even available yet on the rich client beta.

I have a Trazor hardware wallet, and use the Trazor web site to withdraw bitcoin from my exchange.

For each withdrawal I must copy and paste a string of characters from the Trazor web page to my exchange.

It is possible to reuse the same string (from a previous withdrawal) OR each time create a new string of characters.

question:

So is this string of characters the public key - so each time I withdraw (using a new string of characters) into my wallet I am withdrawing into a new location on the block chain - and the Trazor wallet keeps track of all these separate locations?

OR

Is each string just a hash/signature from which a single (same) public key is calculated.

I assume its the second... and that reusing the same "hash" is not a problem because money is going into the block chain public address and not out of it.

thanks in advance.

[is NOT]

I've read many many descriptions of what a wallet address is and I think I am getting to understand it.

A wallet address is NOT a thing that identifies or points to a wallet.

Rather a wallet address refers to an address (public/private key pair) within a wallet but I think more subtly... a wallet creates a signature/hash FROM a public/private key pair that is contained within the wallet. This signature is used to authenticate a transaction without actually exposing the key pair.

A wallet therefore is a container for one or more private/public key pairs and the algorithms required to generate signatures from them.

Did I get that right?

Noob here...

To receive bitcoin all that is needed is the public key (address)

However to spend ones bitcoin or convert it back to fiat currency through an exchange it looks like one must enter a private key.

Transacting with this private key without encrypting it would be unsecure... so how does this work? Is this what a digital signature is?

I've researched this a lot and can't seem to find a clear answer.

Thanks in advance... and for your patience.
