Haha I mentioned it but also in this post https://bitcointalk.org/index.php?topic=5536727.msg65245814#msg65245814 i resigned from it.

and about the second part, I had to add that loading page as when I tested API responses it looks like average API response for each is from 1 to 5 sec (mostly depends on Crypto pairs). So I have 10 services integrated and in the worst case it is 10*5 sec. But average for all is around 26 sec.
As I am not using JS (target audience is also hidden services with onion domain) I cannot block button for the time of getting info from API's so I added loading page, also I switched from getting one by one to getAllRatesParallel() function which is using curl_multi_exec so I can ask each API in same time.
I still need to dive into it, but for now loading page solves my problems, informs users and wait time is not as bad as some time ago.

So for now I have on my list:
-show consistent info if pair is supported, not meet requirements etc.
-work on optimization
-more testing on ECR-20 tokens

Yeah fancy dancy button is not on my list Sorry.
Not every API shows the fees in the clear way.
And who cares about fees if you get exact amount which is listed in Rate column. I need to check if I can do it easily, but I am still not sure about the reason I should calculate it and show.
Don't get me wrong, I am just thinking loud.

With the next update I will try to make it consistent (and remove that sentence), it is hard as each API do it in own way, so I need to go one by one, test pairs and see the result and additionally sometimes everything is mess when value not meet min/max.
But yeah I will work on that.

I have not forgotten this little project
Today I had time for some changes

Version 0.2 - 04.05.2023

• Added About, Changelog, PGP, ToS, PP menu in footer and relevant pages
• Added support for scaling for mobile devices
• Integrated Terms Of Service and Privacy Policy
• Added KYC/AML details note
• Amount input filed converted from text to numbers
• Added loading page
• Added new ERC-20 tokens: DAI, USDT and USDC (They may not be fully functional yet. Work in progress.)

I need to do some more testing and tweaking of the ERC-20 tokens I've added, but this is the first step.

thank you, adding USDC and USDT to the list, curently todo looks like:

-make it faster in response
-fancy button to match the website style - i will keep the button as it is sorry
-add KYC disclaimer
-lock the button once clicked or display loading page after it is clicked before content is loaded
-new column with vendor fees (maybe commercial API for that xD)
-input field as number not text
-check flexbox to make it smartphone friendly
-USDC and USDT and other popular stable coins

Yes reflinks are there, I didn't generate new ones as dedicated for this site, so I use the same ones I added in various places and my other projects (not all providers allow to generate dedicated reflink).

I do not track which source gives me the best income. I am just happy that income is generated

I can just give you some general stats I follow like some of the services allows me to get bonus around 1k USD per month where others gives me 10 USD in the same time. It is also more about how lucky I am and that someone is exchanging large amount of crypto at once using my reflink. For me it is a lottery not a stable income. Just a bonus to my standard salary. Thanks to these reflinks I can have fun and pay for all the VPS servers, domains and create new weird projects. I think of it like reflinks allow me to pursue my various hobby's.

I fully understand and I don't blame you if you forget about it tomorrow This is a hobby project, I will definitely develop it further and add your suggestion to the list.
-input field as number not text
-check flexbox to make it smartphone friendly

Generation time is on the list already.

thanks

Good point. I couldn't have put it better. Thank you.

I will consider this proposal, thank you.

thanks, I didn't add yet too many other crypto as I had to start with something. There are mostly these I am using everyday. I will add some in the future.

Thank you, sir, for your kind words.
It took me about 3 hours one day and 3 hours the second day and maybe 1 hour the third day to get this live. So I guess if I had a day for this project I would finish it in 8 hours max.
TBH I wanted to do everything with ChatGPT, but it's not as good as I would like it to be yet, but maybe that's good, for learning purposes. I told ChatGPT what I wanted to achieve, I tested it on a virtual machine with Debian and Nginx and PHP installed. I monitored the error logs and sometimes added debugging options to the code if something didn't work and wasn't in the logs by default.
Some things I fixed manually as I knew what was wrong. Most of my time was spent reading each API documentation from the vendors to understand the logic and queries. Then I provided the API docs to chatGPT, sometimes as a link and sometimes just copy/paste documentation. I did one API at a time. Only in two cases it work out of the box, in other cases I checked for bugs and provided chatGPT with my suggestions and part of the API documentation that I knew would help. So the short answer is 80% ChatGPT 20% my work. But as I said, my work was understanding API documentation (boring and long) and hunting for bugs and testing with feedback to ChatGPT for fixes.

I need to think about how to speed this up. I have some ideas.

So far my road map looks like:
-make it faster in response
-fancy button to match the website style
-add KYC disclaimer
-lock the button once clicked or display loading page after it is clicked before content is loaded
-new column with vendor fees (maybe commercial API for that xD)

haha, yes I am old enough to remember. I like the idea of the fancy button.
I never think about USD or any other FIAT currency. Maybe I could create a separate sub-site for that, like preev.com, but I focused on crypto to crypto swap. So for now I will leave it as it is.
About the fees, I can try to take it from the API and add another column with a fee, that is actually pretty good idea. About commercial API for that, I am not sure is I am good enough to do it, but let's see what my fiend ChatGPT would say xD

thanks for the feedback

Thanks for the feedback.

- Dynamic floating rates can be done, but it requires Javascript, and the site was built to work fine on Tor. JS is disabled in the Tor browser, and Tor users don't like JS I can think about building it with some interactive parts for users with JS enabled, and if website detect JS is disabled then serve the current version. I have to think about it. For now it is just static.

- The generation time is based on the API response and has nothing to do with the server hardware (it more about network). I now have 10 APIs integrated and they are all checked at the same time, but if one is delayed then they are all waiting for it. I can think of a solution for this.

- Switch button? I think it's about to go to the next stage and swap coins. I didn't implement this because every API solves this in a different way, and if something were broken in the meantime, users would ask me about bugs, not the owner of the API. I do not want to take responsibility for transactions. This is just a simple exchange comparison.

- As there is no JS implemented in the code, I can't lock the button after it is clicked. So if someone will press it twice or more, then the error will be displayed. I have created an error page to limit requests to not ddos my site and not spam APIs requests (they are also limited by providers).

I hope it's clear now. Thank you for suggestions.

Thanks for the feedback. I generally took the KYC information from https://swapspace.co/reviews but not only, because when creating my list on github https://github.com/h0ek/crypto-swap I analysed each provider and read their privacy policy and whether they have kyc/aml.
And of course partially on my experience. I could always make a mistake, but also suppliers can make changes to their policies and I verify this rarely either as someone brings it to my attention or once in a while I verify it myself by looking to see if anything has changed. I know the FixedFloat case, I followed it because fixedfloat used to be my favorite exchanger. Some time fixedfloat was in maintenance mode after these incidents, then they rebooted and it's been good ever since. I have exchanged small and large amounts with them and everything works as it should. Of course, we (as a community) can't forget what happened a few years ago, but I also can't cross someone off for the mistakes of the past. I try to approach it from a distance. It was all on Reddit and forums and FixedFloat stuff always provided some explanations, they didn't disappear. I don't want to sound like a man in a tin foil hat, and I've also seen myself that the site was offline and then in maintenance mode for a long time, but I also don't know if anyone seriously lost crypto or if they were all eventually returned. A lot of unknowns. If you run a crypto site where there is no KYC/AML then if it becomes too popular or someone uses it to launder stolen crypto then sooner or later there will be agents with questions at your door, maybe that's what happened.

I will definitely add a disclaimer in the next update, good point, thank you.

In some spare time, with the help of ChatGPT and some of my skills, I created a website called Cheap Crypto Deal. It compares crypto swaps that I regularly use to exchange my coins.
Since I was always looking for the best deals, I simply combined APIs to display all results from different swaps in one table.
The form is simple, you just have to enter a value, source and destination crypto, then press a button, once the check is done, a table with sorted values is displayed.
Here is the URL: https://cryptodeal.cheap/
you can find it also as a hidden service (it works without JS): http://lp7lxv6tkk4zepitwmf2uo3pzypvmwgglrzhdofekjswjpday7qemgqd.onion/

If you would like to know more about this silly project you can read about it on my blog: https://0ut3r.space/2025/03/23/cheap-crypto-deal/

Not everything works as it should yet, I mean if you set standard, real values it will show you good results, but if you set something ridiculous like 9999 BTC to XMR don't expect to see real numbers I tried to limit things based on each API response with max and min limits, but yeah, probably still something weird can show up.

I will be adding a few more exchanges to the list soon. But if anyone sees any major errors or has any suggestions, let me know, I'll be happy to add something or fix it in my spare time.

For a test, I recommend entering a value of 0.07 BTC to LTC to see how everything works and then your values for testing.

Enjoy.

Yeah, TBH I was thinking from the very beginning that this may be confusing. As also probably all except P2P are automatic, but with some automation behind to stop swap in case of blacklisted address or activity. I definitely need to change that. Adding to the roadmap. Thanks.

Also adding basicswapdex to test list. Once I test it and everything will work I will list it.


I always like to be transparent in the topic of affiliate systems, that visitors are aware of referral links. Then each user can decide itself to use it or not.
Thanks for the feedback.

I gave 5 stars because it is my personal experience, I never had an issue with that exchange, for small and bigger amounts of coins it always worked for me.
I know that until there are more opinions, the rating system will not be very objective. More reviews means more accurate star rating. Fortunately, users can follow links to TrustPilot or, for example, BitcoinTalk and check the opinion of others on a wider scale. That's some kind of alternative till there will be more reviews on my page.

I understand, I had to add at least two to see if the rating system was working properly, I wanted to give my opinion to each one in total, but you're right, it could look like I'm persuading people to use the ones I make the most money on, for example, or I've been bribed. Good point. Thank you.
I will only add reviews when there are more reviews from other users. Or I will add my experience under each page as separate text. But after I rethink what I wrote, I will not do that, lol. I added review section to make users possibile to interact with the website a little and I wanted swap users to also have the option to express themselves without registration and on a portal not controlled by commercial services.

The reporting button is a good idea, I am adding it to the roadmap.


Yeah, supported countries is a good idea for crypto cards, I now have only supported regions in general, countries do not change very fast and back, even outdated supported regions list is always better for users than no info. But you also got the point that all information changes very fast, so I only focus on links and values that do not change too often, or just provide link to place where visitors can find more information themselves. Anyway, I am adding the list of supported countries and KYC/AML info to the roadmap. Unfortunately Crypto cards are all related to KYC I don't think there is company that provides crypto cards without KYC/AML. I know two in US that says they have no KYC/AML but when you read deeper, they have no KYC to some limits, when limits are exceeded, you need to provide proof like ID etc. I could not test it myself because I live in Europe. These cards are available only in US.

I fixed typo in Trocador. I think I spent too much time on the Tor network and I typed it out of habit xD

As for social networking, hmm I'm not good at it and don't have the time or inclination to sit on social media. My official Mastodon is boring, sad and empty let alone for some service. I understand the idea, thanks for the suggestion but for now social media is out of my scope. I prefer to advertise the service on dedicated forums or to the target community through niche and thematic portals rather than announcing to everyone and anyone. I'm not a business, I have no need for big profits. This is a hobby and a passion and if it grows with time it's cool. At least I will be able to adjust the development as to the growth. I hope my point of view is understood.

Thank you guys for input and bookmarking

Haha, awesome reply. Thanks for the kind feedback.

TBH I have some competitors, I have no problem mentioning them, perhaps these pages will also be of use to you and others. These are also the pages from which I draw inspiration but I find them too elaborate and unreadable. For example:
https://www.bestchange.com/
https://www.athena-alpha.com/crypto-exchanges/compare/

But these looks cool and have more features:
https://www.cryptowisser.com/
https://swapzone.io/
and this awesome page for NO KYC lovers:
https://kycnot.me/

My plan is to make all cool features but show it simple without distractors. Like from user for users, and not by big corporation to make money from ads or AI articles.

I hope it makes sense. We are living in a time where people are going back to the internet as it was in the beginning, small private sites or blogs or small communities around a particular topic and we are getting away from big corporations and social media.

Clean and simple with specific information on a particular topic.

I have been swapping all kinds of cryptocurrencies for a long time and always have a list of my favorite swaps. I once made a list on GitHub of all the ones I personally used. I added my reflinks to the list. Some money came in and I thought I would use the money to build a website where I would list everything and add more information than on the GitHub site. So the Swap.Cab website was born.

It lists all the services that allow you to exchange cryptocurrencies, with all the information I find useful. My reflinks are there too.

I created this site for two reasons.

The first is that I wanted to share the information that I have collected over the years on various services related to the exchange of cryptocurrencies, perhaps someone will find it useful and facilitate their own research when the time comes to exchange.

The second, of course, is money. Nobody ever gives anyone a grant to develop their own hobby projects. From my own experience, I know that reflinks to these services have allowed me to earn enough to maintain my own servers and develop my passions and hobbies without depleting my household budget.

Here is a link to the Swap Cab, of my new hobby project.
https://swap.cab/

And here's a link to a roadmap of what I plan to do next and what I've actually already done.
https://swap.cab/roadmap/

There is also a list of providers of debit cards that can be loaded with cryptocurrencies, which I will soon expand to include features such as the swap services table. This is actually the next thing I will be focusing on next week. And then the next things on the roadmap.

I am open to suggestions, if anyone wants to criticise me a lot I will be grateful for constructive criticism and not just calling me stupid

I encourage you to add reviews on the services listed if you have used any of the swaps. I will be able to test the addition and moderation of ratings in this way. There is a captcha but no email confirmations yet.

Thank you for taking the time to read my post and check out the website.

Cool list, it was also one of the sources to the list I built.
If someone is interested can check here: https://github.com/h0ek/crypto-swap
Please bear in mind my list contains referral links.
Suggestions are very welcome.

Yeah thanks I am still celebrating that you never gave me back my coins I tried to exchange using your service.
From that time I am using MorphToken and SimpleSwap which I recommend as very good, fast and trustworthy service, never had a problem like with Godex I described in previous posts.

looks nice and I am interested but...

...I have a question, even a few questions:
1. Fee in % is taken every time when someone buy a ticket or at the round end from the jackpot price.
2. Jackpot prize should be set to 0 at the beginning, and it will automatically change when someone buy a ticket? It will get back to zero at next round and start counting again depending on the number of tickets purchased minus a fee? Why this is something you can set manually? If I set this to 10, then how someone can win this if the value doesn't exist I mean there is no crypto.
3. People login using their wallets, so if I know someone else wallet it means I can access his account?
4. Do you plan to create user accounts with passwords and maybe even 2fa (like google authenticator or authy)
5. I can use block.io or coinpayments or both at the same time? block.io is with no fees and coinpayments have 0,50% fee, so it is already added in ticket price?
6. If just one person buy a ticket for let say 1 BTC, fee will be 1% then jackpot is 0,99‬ BTC and if someone would like to withdraw it using coinpayments then 0,99 BTC - 0,50% coinpayments fee.
7. How long do you plan to develop the script, is there a roadmap or you just implement customers ideas.
8. How the support looks like?
9. Do you make some paid customisation on demand? What is the price list, per h / per customization?

I know these questions may seem obvious, but I would prefer to be officially asked, so that there would be no understatement afterwards.

thanks in advanced
