[ANN] Metaexchange.info bitBTC gateway, soft launch

[monsterer]

Seems to be working ok now. Weird, I did confirm the certificate fingerprint as I'm accessing through Tor. Even though a misbehaving/malicious exit node is rare in my experience, it can happen.

Did you change anything server side just now?

No, nothing changed.

SSH is protected by denyhosts.

I guess it's no big deal as you're not holding funds.

Security is always a concern, I take these things seriously, regardless of the fact that we don't hold funds. I don't lock SSH to one IP address because I like to work in different places around town. denyhosts prevents anyone not on my ip whitelist from failing to login more than twice.

End result is the same though, have to reuse an address if I want to send funds to the same account >1 time.


So far it seems to be working fine, bitBTC have been credited. Good job!

You're welcome.

[karnal]

I'm showing no such certificate errors in chrome - what version/platform are you testing on?

Something else, the deposit address seems to be a function of the bitshares account name.

Deposit address is reusable for multiple deposits to the same market, and is not a function of account name, it is randomly generated.

Thanks for testing, though

The encryption is too weak. You are using TLS 1.0 and with chrome it negotiated AES_128_CBC, with SHA1.

Use TLSv1.2 and at least SHA256 for hashing. Use ephemeral DH.

Also, at least on chrome, the certificate shows as invalid. You probably forgot to include the certificate chain.
No problems on firefox (and yeah, I confirmed the fingerprint, it's not a mitm).

Also, your SSH port is open to the world which is usually not necessary.


As for the service proper, I'll let you know. Just sent a small amount to test.

Reusing addresses in bitcoin severely compromises privacy. Please consider changing this part of the system.


On a side note, good catch on detecting whether a bitshares account is really registered or not before accepting it.

Used this a little while ago to get some bitBTC. I was surprised at how fast it was. Its nice being able to convert btc->bts without having to go through a centralized exchange. Awesome!

[monsterer]

Got the message, we're back up again

[Shentist]

Is the exchange working?  I'm not seeing any value / amounts?

Maximum BTC per transaction

thanks for the information.  i informed Paul, but probably he is still sleeping -  to early in Europe.

BTER hacked! Terrible news, but this makes our mission much stronger.

Try our bridge today and give us feedback.

We strongly believe that it is important to minimize 3rd party risk as much as possible, so we are holding your funds only for a couple of seconds. To be true, anyone could or will be hacked, so you want to less exposed to this kind off risks as possible.

Today monsterer updated the site:

- we are now providing https
- API documentation are now available

We are slowly increasing the available volumen and will for the next step will add more trading pairs!

metaexchange.info

[Shentist]

we are slowling increasing the transfer limits, so try metaexchange.info and let us know if we can improve something.

[monsterer]

FYI until now my status is always down
nothing changed the last days...

Thanks for the heads up - just fixed the display bug

[Shentist]

Service status: Down
http://metaexchange.info/
?

The site polls the deamon to get it's active status, but due to RPC calls lagging by over 30 seconds sometimes, there can be a big delay which causes the daemon to look like its gone down to the site. I'll have to increase the time it waits before declaring man overboard!

FYI until now my status is always down

at work i have the same issue, maybe because of a firewall?

service is "green" and running.

Why is the bitBTC -> BTC rate higher than the other way round?
Woudn't it make more 'sense' marketing-wise to flip that rates?

The rate is adjusted to account for the bias in our holdings - simple inventory management

[xeroc]

I hope you add bitUSD and NoteUSD once Bitshares Music is ready.

we will work on both!

right now, it would be great if some more people are trying and give us more feedback. did anything got right, do you miss some kind of information etc.

thanks a lot!

Valentine is working on getting the shapeshift API in the full node, afaik.

You could copy theirs to make it as simple as possible to also just add metaexchange through the same calls.

https://shapeshift.io/api.html

It would be sweet if the you say to the wallet you want to, say, send bitBTC as BTC, and then the wallet automatically gets the rates from every gateway you have indicated you trust through "gateway.com/rate/bitbtc_btc", and then returns those that support it in an ordered list with price and send limits.

Perhaps in the long run its better to have the rate and limit requests be combined, because when markets are efficient every bridge will be able to offer to exchange any amount, but the spread will increase as you need to send a bigger amount.

[fuzzy]

Well done!! 

What are plans for this platform going forward?

How can we take advantage of having our own in-house shapeshift?

The first thing we want to do is add the other bitAssets, the API and to raise our transaction limits and then we can starting thinking about the next phase for the project.

We would love to be included in the bitshares wallet and are more than happy to do whatever it takes to make this happen.

Any confirmation if this will be included in the BitShares wallet?

Not as i know, but maybe fuzzy can ask this on the mumble session to bytemaster. what is the easiest way to integrate this service directly into the client. Paul is working on API so in theory it is absolutly possible.

I'll ask on the next hangout.  No issues there.  Good work thus far guys.  I'm looking forward to seeing the final product!

do you have any logo or someting out there!? IF, could you pls send it to me!?

I'm preparing deposit/withdraw yet! It would cool if i could get the chance to include you logo as well!

no, we have no logo at this point in time, if you have suggestions we are open to take it

  Great job. Very smooth.

Question : will we ever be able to process credit cards > BitAssets using this?  We need a way to convert fiat.

Sorry about that - it seems your deposit was refunded due to an internal error: https://blockchain.info/tx/1e2baa981784a8557574eb6ae414af37cb2608038fe2540c48ce30d318f890ea

I'm looking into the problem now

I have closed my btc wallet so I haven't noticed the refund

Thanks!!

[monsterer]

I tried the service Btc -> BitBtc but until now I haven't recieved any bitBtc (no problem, it was only 1mBtc but it is good for testing).

This is the transaction (now has 7 confirmation):
https://blockchain.info/tx/ed935e1e2dcda8c5996521f6c2c1f0b2383a1af0446779be7beb37dd951ce8eb
The btc address is 134YyqcrfDNabsVnS5SoKMTvJHjEjtVcZP
The username in bts blockchain is: fabiux

I tried also wallet_rescan_blockchain with no luck.

Tip: It could be useful having a page  so I could track the bitcoin transaction and bts id transaction when it is available.

Thanks!

No I mean to say that I'm lazy and don't like copying and pasting text. You can use a bitshares url to open the bitshares app and input the appropriate recipient and memo information. 

[Shentist]

For the sell BitBTC side it would be great if you provided a bitshares url for the transaction.

you mean, in which block the transfer get executed?

we have our own ideas, but we are open for input!

at this point in time it is just - proof of concept, with small amount

as Paul said the next steps would be integration of more bitAssets like bitUSD!

we would also like to integrate this directly into the wallet. we are funded from the community and we want to have the spread as low as possible without loosing funds.

The advantage is we are only working for the success of BitShares and we can focus what the community thinks what we should do!

So i hope anyone will try the service and will give us feedback, what we should do better or different etc.

[monsterer]

How is your limit managed? 
How do you manage the risk on the back end?

Limit adjusts as a percentage of holdings on each side. Right now the prices are fixed, hand adjusted, this will potentially change going forward.

Just used it.

Moved BTC out and in.

Great work!

[Rune]

This is awesome!

We now have 3 bridges all operating in different niches: Shapeshift, exchange.BTSBOTS and metaexchange. I think all of these services will converge and begin competing over time, offering the same kind of full-range bridge services, and I assume will all begin to offer shapeshift-style API for easy integration with other products and services. It will be fantastic if we can have these 3 services all competing and fully integrated in our wallets as the tools that allows bitshares to use bitcoin as its rails to deliver an optimal and seamless user experience. With many competing services in this vital area users can choose the service that is offering the best spread and will benefit immensely.

[cass]

  awesome!

This is a "bridge", not a "gateway". Gateways issue UIAs and hold reserves.

But, awesome!

Hi everyone,

It's finally time for the soft launch of the Metaexchange bitBTC gateway! Metaexchange is a bitshares exclusive on/off ramp into bitAssets via bitcoin. We're starting with bitBTC because there is currently nowhere to get it outside the internal exchange, but we will be adding ALL other bitAssets gradually over time. Please let us know which bitAssets you would like us to add next!

We are funded by the blockchain, making Metaexchange one of the first in-house bitshares products to launch. As such, we're 100% open source, so you can fork us - the link to the repository is on the site. We answer to you, so we'd love to hear your feedback!

http://metaexchange.info/

Cheers, Paul and Frank.
