Title Lumenswap - Decentralized swap protocol for the Stellar network. Summary Lumenswap is a decentralized swap protocol for the Stellar Network that allows you to convert assets on the network using a friendly, minimal interface. Category Applications Goals Lumenswap aims to create a simple and minimal platform for swapping assets on the Stellar Network. This allows users to learn about the power and fundamental features of Stellar for moving assets. The benefit of Lumenswap for the Stellar Network Having more applications that allow users to move their assets will make it easier for users to work with the network. This, in turn, increases the liquidity of the assets on the network. However, these applications can only achieve their goals if they have beautiful user interfaces and create enjoyable experiences like StellarX and Stellarterm. Structure Overall structure Client -> Lumenswap-> Horizen -> Stellar network Swap Here, you can convert your assets. Here’s a more detailed, technical explanation: Once you submit a swap request (e.g., 1 BTC for 10 ETH), we send the request to the network using Horizon API and perform a path payment strict send operation (with you as both the sender and receiver). Depending on your order size and Stellar’s order books, if the order can be handled, you’ll receive a success message and the swap will be performed. If the network cannot handle your order based on that moment’s order books, you’ll receive the following message: “Your order is too large to be processed by the network. Do you want to register it as an active order on the network?” If you approve the message, we’ll run a manage buy operation using Horizon. The order will remain open and active and it’ll be executed to the possible extent. The remainder will remain open and can be managed in the ‘Active orders’ section. Send (soon) There are two types of requests: 1- Basic send This is a normal asset transfer to an address on the network exactly like you do in your wallet. After submitting the send request, it will be sent on the network using Horizon API and a payment operation will be executed to transfer the assets to the specified address. Just like that. 2- Send + Swap This is perfect for when you want to send one type of asset and have the other end receive another type. This is like hitting two birds with one stone: first a swap and then a send. Suppose you want to send $200, but the receiver specifies ETH as their preferred asset type. To do this, you need to activate a Send+Swap switch. As usual, a request is sent to the network using Horizon which involves a path payment strict send operation (with your address as the sender and the entered address as the receiver). If the network can handle the order based on its order books at the moment of request, the operation will be executed and you’ll receive a success message. Otherwise, you’ll receive an error message. In this case, you can increase the tolerance to reduce the minimum received value so that the network can handle the request. Note: This section will be released on July 15 Minimum received This is the minimum amount of an asset you’ll receive after the swap. The network will always give you the best recommendation, but this specifies the minimum amount. Set slippage tolerance This shows the minimum you’ll receive. Higher percentages mean you’ll receive less. Path This represents the best path to convert the specified assets based on the order books on the network. Orders page This part consists of two sections: 1-Active orders Here, you can view and delete your open or active orders. 2-Completed orders Here, you can view the completed orders or trades. Calculator for estimated price Lumenswap calculator uses the last registered orders on the network to estimate asset prices on the network (the calculations are performed using pairs of XLM and specific assets). Suppose you want to get ETH in exchange for USD. Once you input 1 ETH, you’ll automatically get 200 USD. How are these values calculated? In the example above, we’ll obtain the USD/XLM price based on the last buy order on the network and determine ETH price based on the last ETH/XLM sell order. The calculated number is then displayed on the interface. Note that this is an estimation and not an exact number. Note: based on our observations of the order books, the best paths mostly consist of XLM pairs. For example: SNT -> LLO Best path: SNT -> XLM -> LLO Connect Wallet To use Lumenswap, you need to connect your account. Right now, there one way to do this: Private key: To use this method, you should directly enter your private key. The key will be stored locally on your browser and deleted as soon as you log out or refresh the page. (Lumenswap is an open-source application and you can review our source code to make sure everything is normal). Soon, we’ll have two methods by connecting to the Ledger. Listening assets Given the free and distributed nature of blockchains, we designed Lumenswap to let anyone swap any assets. Right now, popular assets with sufficient value are available on the platform. You can also add custom to be swapped using the following format: Format: lumenswap.io/Asset code1-Issuer address1/Asset code2-Issuer address2 For example: LAX -> ETH lumenswap.com/LAX-GAZZB5KPOWEWK4C5S5H5B6YPR2EQMUIJEFFBNQ6MWYYAG7DOEELBOHLW/ETH-GBDEVU63Y6NTHJQQZIKVTC23NWLQVP3WJ2RI2OTSJTNYOIGICST6DUXR Note: Use ‘XLM’ for XLM asset. For example: LAX -> XLM lumenswap.com/LAX-GAZZB5KPOWEWK4C5S5H5B6YPR2EQMUIJEFFBNQ6MWYYAG7DOEELBOHLW/XLM Links Website: lumenswap.com Gitlab: https://gitlab.com/lumenswap.com/lumenswap.com Email: vladimir19kholodenko@gmail.com Tags Swap - DEX - Exchange - Transfer

Lumenswap Easily convert your on-chain assets. please send your feedback for improve Lumenswap.

How do you select the list of assets that can be swapped? Currently there are half a dozen assets but it's missing some of the major fiat and cryptocurrency tethers. Those would be really useful to have.

marcinx Hi Marcinx, Thanks for feedback! Yes, we've listed a few high-volume assets at this stage and in the next update, we will list more assets. Also, you can list any assets you want, please follow the Listening assets section

Like the idea and simplicity! Looking forward to signing options outside of pasting a private key 😀

kolten Hi Kolten, Thanks for feedback! We agree with you, this is one of the features that will be added in the next update (~ July 15)

Lumenswap It's great and creative app. You've used different operations with different properties in Stellar to create a useful application. Keep growing.

Really simple and convenient exchange. How do you plan to earn? What business model does your project have for the future?

John Hi John, Thanks for feedback! Yes, we used four operations to build Lumenswap: Path Payment Strict Send Manage Buy Offer Change Trust Payment in Stellar, you can create smart contracts if you correctly use the operations and fundamental features of the network such as Batching / Atomicity (which you can use as a guarantee and condition because either all operations in a transaction succeed or they all fail). This article by @kolten helps you understand this.

Scopuly Hi Scopuly, Thanks for feedback! There's no special business model because Lumenswap is an open source and free application, which anyone in the world can use to convert their assets in the Stellar network. The team's expenses will be covered by SCF grant.

This project looks like thin wrapper around Horizon's path payment APIs with a GUI resembling Ethereum's exchanges. Not sure it's accurate to call Lumenswap a "protocol" when it's just using Horizon. Also didn't you guys just win last SCF with Lumenscan? I think its bad taste to submit a new project so soon especially since you've been caught using Stellar.expert's private APIs and had to reduce Lumenscan's functionality as a result. Orbitlens estimated you have at least one year of development time before Lumenscan even comes to par with Stellar.expert. Given how much you marketed Lumenscan as being "superior" than stellar.expert you should at least replace that missing functionality and continue building Lumenscan.

I have only one account here and in any social media related to Stellar.

Oh good! We are a community and we must help each other to grows Stellar ecosystem, Not to destroy each other with baseless things.
At first, we wanted to add Cosmic to Lumenswap, but when we saw this behavior from its CEO, we removed it from our roadmap.

MisterTicot

Lumenswap

I believe you guys have more than React in common though. Would you help me figure this out?

It looks like your systems all generate a bundle.js, a nearly empty load.css, and a bundle.css. Which tool is setting things up that way?

I also wonder about how are those files generated: index.html, base.less, font.less. Is it hand-written or is there some scripts/standard utility behind this?

dzham

Lumenswap 1-Almost all websites in the world use Cloudflare (Always https is the default option for Cloudflare)

The chance that two websites use the exact same cloudflare nameservers is quite small though.
So by pure luck then, all of the sites that go through my cloudflare account happen to have the same setup. Go figure...

Hey @Lumenswap would you mind pinging me on Keybase? tyvdh?

Lumenswap

Hi guys Do you want the Lumenswap team to work on the next updates?
And do you want us to continue in a fair environment, away from the influence of mafias? Because their project has no creativity, and they want to get the grant by marginalising the other projects.
Is the world built on justice or power?
We've worked hard on our project, and is this unilateral destruction really fair?
I think they're mad because Kolten left us a positive comment. He is very smart and understands the difference between unoriginal and creativity

dzham

Lumenswap I think they're mad because Kolten left us a positive comment. He is very smart and understands the difference between unoriginal and creativity

What creativity? It's a web front end for doing a path payment, for Christ's sake.
The most creative thing you've done is the "Swap Request" flow-chart in the OP.

Lumenswap

dzham

It's a web front end for doing a path payment, for Christ's sake.

I can’t figure out if what you’re saying is based on ignorance or animosity.
All decentralized apps are built using blockchain operations + a web UI.
For example, most Stellarterm structures are build using manger buy offer and manage sell offer This does not mean they’re rudimentary. It’s actually creative to be able to use and combine different operations in a way that yields superior results.
Plus, we’ve used multiple operations to build this app, but you don’t see Lumenswap because you choose not to.

We recommend the best price based on network awards.
We’ve implemented the components in the best way possible and leverage a minimal design to create a simple environment to move assets. Our app is completely open-source and decentralized.

Isn’t Stellar a blockchain for simple assets Convert and transfer?
Does a regular use know what Path payment strict send is? Clearly not! But they know what simple asset transfer means and know they want to get their job as easily as possible. So, when they log on to Lumenswap , they can do what they want without knowing what happens in the background.

dzham

Lumenswap I can’t figure out if what you’re saying is based on ignorance or animosity.

Could be it's just disappointment of something not actually moving the needle.

Path payments, together with what can be done using transaction envelopes ("multi-sig", etc) are the distinguishing features of Stellar, and deserves something better than just slapping a UI in front of an API call.

I would have hoped someone would have taken it further, that's all.

(As an example, is anyone doing multi-path payments?)

Lumenswap

And then there's the (at least) 2549/2550 chance(*) that you are behind both lumenscan/lumenswap, and lying about it.

(*) - cloudflare name server pairs get assigned randomly on a per account basis, and all domains w/ an account have the same name server pair. The numbers I've seen say there are 51 male names + 50 female names, and every account gets one of each -> 2550 combinations. Old numbers, so quite possibly even more combos now.

Lumenswap

dzham

All projects in the world are UI in front of API's call.
You that know and you're talking again.

Lumenswap

dzham
Keep these words for yourself
Soon we will talk about you and the mafias that you take in every Grant period.
You receive grants every period without showing yourself and you think everyone is like you.
We've put a lot of time into our project, and what's bothering you is that users have made positive comments (except for you and the Mafia group, of course).
Unfortunately

Lumenswap

dzham

Of course, The projects of the previous period are only Lumanscan, which is being used and the rest is not used at all.

dzham

Lumenswap You receive grants every period without showing yourself and you think everyone is like you.

My account here is connected to my keybase, which has my github profile, which contains all code I've ever released for Stellar. Coincidentally, it also has my real name, my twitter, and my websites. How is that "without showing myself"?

And can someone please send me the grants I've apparently received every round? They seem to have been misplaced.

Lumenswap

dzham
If you are right, why don't you comment about Cosmic?
We all know that Stellar can't have decentralized voting without VM
You can ask from Jed McCaleb To prove it

Lumenswap

dzham
Why don't you say that Cosmic just made manage data operation + UI
So if you have directional thoughts, keep them to yourself

dzham

Lumenswap We all know that Stellar can't have decentralized voting without VM

The people saying it can't be done shouldn't stand in the way of the people doing it.
There's at least three different solutions being worked on right now.

Scopuly

Now all the projects and all the developers are important on the Stellar stage, including those who were called the mafia here) These are people at the source, however that may be, and this is important. We are all united here by one goal - that would make Stellar as applicable and popular in the world as possible.

The Stellar ecosystem is still missing one important service for the community and developers - it is a voting service for the submitted projects. Something like home for Stellar startups. Then each submitted project would have a history of development, phases of receiving grants and constructive criticism around startups.

This would give a couple of powerful effects for all participants:

A complete list on a single domain of ALL existing Stellar projects
A transparent history of the development of the project and the amount of grants received (this would encourage other new developers to think at Stellar)
This would exclude random one-time projects that are aimed ONLY on receiving a grant
Also on this site would be not only users and developers, but also investors who are eyeing Stellar projects
“And in the end, it could be a place to concentrate best practices on Stellar development, best practices, tips for beginning developers, etc.
Well, of course, this would attract more media and bloggers to this resource to study reviews of the fast-growing Stellar ecosystem

At first glance, developing such a project does not seem complicated (maybe I'm wrong) . There are so many talents and everyone could make a preliminary contribution in the form of a sketch-concept of HOW this service can look and work.

Lumenswap

Hi everyone,
After a discussion with the @tyvdh , we've decided to participate in the next round. We're going to withdraw from this round to focus on adding the new features we planned to include in this round. See you soon with more features.
