Topic: eXch - instant exchange BTC / LN / XMR / LTC / ETH / ERC20 - page 32. (Read 27792 times)

A little clarity for those who have never tested eXch.

Even though you can ostensibly choose "BTC/BTC", you will not be able to make an exchange. Perhaps sometime in the future the eXch team will rework the anatomy of the drop-down list so that the "Exchange rate not found for BTC/BTC" notification is instantly displayed when you select "BTC/BTC". But to be honest, this is not so important since you will receive this notification as soon as you try to enter your Bitcoin address or click the “Ex/Calculate” button

If you remember I was the one who first notified you guys about this suspicious clone ''exchange'' a while ago
It was obvious to me they used everything from eXch and made some silly excuses when I asked them about this in their ann topic.

We have recently discovered that some service named "MrStork" has advertised an exchange platform on this forum with a rip off of our web-design. While we have no evidence (for now) that this specific service is a scam scheme, we believe it is a potential scam scheme since nobody with proper ethics would blatantly rip-off other service's web-design and advertise as a new platform.

There was already an "exchange" that ripped off our design completely called SWP[.]CX and was proven to belong to a known scammer (more information here https://anir0y-scams.info). There are however already some signs that "MrStork" might be related to that scammer. We also believe that MrStork might be responsible for recent DDoS attacks targeting eXch because the stylometrics used in their announcement thread match emails containing threats we received from the DDoSer.

We strongly recommend avoiding any services that are blatant and obvious copycats of other known and established services.

I was curious ; so I did a small test. I sent some satoshis with a 26 sat/vB fee. Waited for eXch to detect the transaction. Bumped the fee to 44 sat/vB.

The exchange was successful, I received my coins. I think the service only consider the first transaction with 1 confirmation to the address given for the swap, no matter what the interface is displaying (the interface indeed did not update the txid when I did RBF until the deposit got 1 confirmation)

Thank you to both of you GazetaBitcoin and NeuroticFish for sharing the raffles in your locale section 

I've a question regarding the interface: Is RBF currently supported? (I haven't found it in the FAQ).

Recently I started an exchange and saw the fee of my transaction was too low, so I RBFed it, and the TXID of the transaction changed. However, in the exch interface, the original transaction ID was still shown as the deposit transaction, even after several refreshes. To be sure, I double spent the transaction before it got confirmed and started a new exchange.

My question is that if the RBFed transaction gets finally confirmed, will it be recognized by the exchange?

Chances are big that the answer will still be the same:

@eXch when will you add Solana?

Thank you for the heads-up, paid2! And many thanks to eXch for all these raffles! One more to go and half of them will be finished...

I announced this raffle too in the Romanian translation of OP and NeuroticFish did the same inside the thread dedicated for contests Good luck!

@eXch
Since you are already supporting LTC and you probably run litecoin node, may I ask if there a chance you can add support for Litecoin mweb addresses on your exchange?
This will increase overall privacy and you could be one of the first exchanges to add support for mimble-wimble in Litecoin.
Litecoin Core wallet already supports ltcmweb addresses, another wallet is forked ElectrumLTC.

I know I would like to see the TRC20 version of Tether's USDT. But the network fees on Ethereum have gone down significantly in recent weeks. I often see recommended gas fees between 6-10 gwei. Converted to a USD equivalent, it's currently cheaper to transfer USDT on the Ethereum blockchain than it is on Tron. Tron asks for 13 to 26 TRX per smart contract interaction, depending on congestion. That's up to $3. The situation can change quickly, though, so I am hoping the TRC20 version will still be added in the future. 

I know that there was a discussion about it earlier, but what is the final statement, will there be or is it planned to integrate other "cheaper" networks than Ethereum and ERC20? I imagine that many would like the possibility of swapping to TRC20.

This is why we put a lot of effort into changing the username eXch.cc to eXch. 

The thing is, people who don't know how to differentiate the real from the fake could easily get tricked with scam social media pages as well. I see people in my Facebook friends circle share them all the time. Fake car giveaways from fake dealers presenting themselves as the real ones. I have seen people share fake cash giveaways by fake bank profiles. PlayStations, smartphones,... everything. It's usually relatively new sites with a few general posts and then a giveaway which requires the usual (like, share, comment, befriend). And people fall for that kind of thing. Logic stops as soon as people think there is something to gain for free.

I good security practice,  which I do for basic every website which I will pay something,  is to double check the address with their social media links.

In this case , bitcointalk is like a social media platform.

I would never enter my financial details or make a cryptocurrency payment without double checking the URL in other platforms such as their social media profile.

I think people who are using this exchange and are active here on Bitcointalk know how to find the official website, both the .tor and clearnet versions. I have bookmarked both a long time ago. The problem is reaching it from outside of the forum. The typical person isn't as security-conscious as a bitcoiner. If they had positive experiences with such onion site directories in the past, they will unfortunately not think twice to trust it with pointing the way to eXch. At that point, they have already taken a big step towards getting scammed. 

Warning: scammers are placing fake TOR onion site links on site directories (sites with compilations of other TOR onion links) like DarkDotFail for exchanges like Exch to take them to scam clones. Do not use onion directory websites to find any crypto exchange. Only use the official links on Bitcointalk or altt. Please stay safe everyone.

Here is the blog post I first found this information from: http://xxkdkmhcrw7mug2nhtorvsusrydoqtfxggeu3rxcxglh3jk7ltmlmeqd.onion/

Here is a screenshot for those without Tor Browser



As you can see, it is very easy to impersonate any TOR site just by generating an onion address that has the same first and last characters! So be careful!

Our email is [email protected] but I recommend contacting the "SEAL 911" team from https://securityalliance.org - a non-profit organization consisting of many volunteering entities and organizations specializing on blockchain analysis that have promised to provide free help and guidance for crypto heist victims. They will for sure provide you with all the necessary assistance for your case. Just a friendly tip - avoid Josh_CB from Cryptoforensic Investigators because he is toxic and incompetent.


It's true (in regards to FixedFloat funds).

1. Any custodial service that holds your crypto has full control over it thus can freeze and confiscate the funds. This concerns custodial wallets, centralized exchanges, smart contracts with freezing capabilities owned by centralized entities (such as Tether's USDT and Circle's USDC), cross-chain bridges (such as Avalanche Bridge that confiscates "dirty" BTC and ETH) and even some rogue cryptocurrencies (i.e. https://github.com/bitcoin-sv-specs/protocol/blob/master/updates/confiscation-transactions.md).
3. No, since we have never froze any crypto nor have any technical capability for doing so.
4. We have never encountered such situations before, so we currently have no protocols for such proceedings. We are also not a financial institution nor possess any money transmitting license due to the fact of operating with something called "cryptocurrency" that is not considered or recognized as a financial instrument by the most central banks, therefore not required to implement any. If Lagarde publicly admits crypto is a financial instrument, then maybe we will reconsider this, but until then we see no reason for even bothering for these concerns.




Coinos node doesn't appear to have the effecitve peering scheme for optimal routing and we had no routes to Coinos earlier but after this incident we have opened a direct channel with them: https://1ml.com/channel/923451228984246272

Payment of their invoices shouldn't fail anymore.

Since we got a bit more confident with LN lately and now have better understanding of its possible edge cases that might cause security risks for us, we will soon optimize LN payment response handling so customers won't need to wait for these errors to be reviewed manually by our team.


They haven't asked for any data type in specific: "[...] Please provide whatever records you have for [...]"


Can confirm.


It reminded me that some time earlier, some SlowMist rep explained to us that they refer to our service as a "mixer" in their annual reports exclusively because of what we post on Bitcointalk. L. O. L.

Apart from that, I always was quite sure this forum is frequented by state officials. Take for example FIOD (NL), who even have an account here.


I have decided to provide this data voluntarily in order to help flatten the investigative curve a bit so they don't have to bother theymos.





After communicating both via support tickets and emails today with this user, turned out they have used xmrwallet[.]com as their wallet and the destination XMR address was hijacked during sending, so their funds went to some other direction but not to the correct eXch deposit address. This was done either by the mentioned wallet itself or by the buffer clipper malware their OS is probably infected with. Also there are other users who had issues with that wallet earlier https://github.com/monero-project/monero/issues/8440#issuecomment-1186785857

We have also verified that the view key they provided didn't match the output corresponding to the correct deposit address.

Unfortunately, it's not the first time someone being a victim of such circumstances among our users. We have some wallet recommendations here that are relatively secure wallet options: https://exch.cx/faq#wallet_security_recommendations (Blixt wallet will be removed from this list during a next engine update for ignoring our multiple requests to provide updates on F-Droid inclusion)

I appreciate the concern. I'm not exactly nervous (if you knew the images they post, you would see that yours are the ones with the least private information). I just alerted you to the fact that some of the agent's personal information was exposed, which is not something that is recommended, not even for you.

In fact, the way you now explained the situation, and very well, it was much better that you managed to omit all the agent's personal information.

Keep up the good work, and I really hope you continue to operate in the best way possible.

Everything has been solved. Was fully my fault. Excellent Customer Support from eXch. Keep it up.
