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.

Hi Afreum, We are glad that Lumenswap can help you
please send the asset info (asset code, asset issuer, website)to this email.
vladimir19kholodenko@gmail.com
After reviewing, we will add it to the list of known assets.
Thank you

Afreum

Lumenswap Thank you so much.

@Lumenswap - This looks great. We are exploring to see if this can be added as an option for new/existing Users to buy EVER coins in our project - EverLife.AI. I have emailed you our issuer id and asset code details. I look forward to hearing from you.
