[Asset Hub](https://forum.polkadot.network/t/assethub-vision/6934) is a Polkadot system chain slated to hold major assets (including DOT, USDT and USDC) in Polkadot’s [Minimal Relay Chain architecture](https://github.com/polkadot-fellows/RFCs/blob/main/text/0032-minimal-relay.md),  as well the potential developer friendly locus for [contract-pallets](https://polkadot.polkassembly.io/referenda/885) and consumer-friendly ["Plaza"](https://www.rob.tech/blog/plaza/).   

This proposal concerns [dotswap.org](https://dotswap.org), an Asset Hub DEX UI, developed by [MVP Workshop](https://mvpworkshop.co/) with support from [Colorful Notion](https://x.com/colorfulnotion):

* [Dotswap.org V2 Video Overview (with voiceover)](https://drive.google.com/file/d/1gTOqJ60jmij-v5BibbYBzp0d1DmhlvYg/view) 

MVP Workshop and Colorful Notion are 2 long-term Polkadot ecosystem teams who have worked together successfully this Spring and seek to work together for the rest of 2024.   This proposal concerns retroactive funding for dotswap v1 for Q1/Q2 2024, and support for v2 development and hosting dotswap.org for Q3/Q4 2024.

[dotswap.org](https://dotswap.org) aims to be a full-fledged interface for users to manage Asset Hub-related assets, with key functionality of swapping assets using a new assetConversion pallet on Asset Hub, as well as basic gateway between Asset Hub and the Relay Chain (v1) and major parachains (v2) and Ethereum (via [Snowbridge](https://polkadot.subsquare.io/referenda/944)).  Following the [Asset Hub Vision](https://forum.polkadot.network/t/assethub-vision/6934) and the new [Polkadot app](https://x.com/Polkadot/status/1811342289735655651), we envision dotswap.org to be accessible for _everyone_, from beginners to lightweight traders rather than just advanced traders and Polkadot experts.

## Details

Using the working v1 implementation and v2 mockups, in June a usability testing session was conducted with 15+ members active in the Polkadot OpenGov community.  Results are compiled here:

* [Report](https://docs.google.com/document/d/1r3QPm9ET5hoQ49rBcg-M2LBaQWQmfZeq4MaQAnHiKgs/edit)
* [Raw data](https://docs.google.com/document/d/1rpfl0Q0LFePfpbGwANewZ6ncbqD6h-RVMjVBL3srcxA/edit )

Based on the above user feedback, we have compiled the following roadmap and budget:

## Dotswap v1 Feature Summary

The Dotswap.org v1 feature enables a basic asset swap dashboard centered around Asset Hub.

#### Dashboard

Enables users to see all their assets on Asset Hub and the Relay Chain.

#### Swap

Enables users to swap assets on assethub with the new “AssetConversion” pallet, and also add and remove liquidity to Uniswap v2 style liquidity pools

#### Cross-Chain Transfers

Enables users to move assets between Asset Hub and the Relay Chain

## Dotswap v2 Feature Summary

The basic functionality is expanded upon in Dotswap v2, summarized below, with much of the functionality below demonstrated in the [Dotswap.org V2 Video Overview (with voiceover)](https://drive.google.com/file/d/1gTOqJ60jmij-v5BibbYBzp0d1DmhlvYg/view)  

#### Feature: Foreign Asset Support (WETH/WBTC/…, MYTHOS/…)

Through Snowbridges and standard parachain channels, Asset Hub will have assets from:
* Ethereum eg WETH + WBTC + PEPE + SHIB (possible now, tested [here](https://x.com/colorfulnotion/status/1808927242803892637))
* Any parachain e.g. MYTHOS (possible soon, testing in progress as of July 2024) 

The dashboard will simply show foreign assets and enable all the same operations:

![image](https://i.ibb.co/8KHqzD2/4113-sourabhniyogi-1720837784243.png)

#### Feature: DOT/X + X/USD Graph presentation

Recent swap activity for any assets (measured against DOT or USD) will be accessible from the Swap page and Dashboard page.  A third-party API call be used to fetch the graph data, cached from BigQuery / Dune on a regular basis:

![image](https://i.ibb.co/wdtZ6Q4/4113-sourabhniyogi-1720837101513.png)

#### Feature: Pool Volume + APY presentation

While liquidity pool providers are a tiny portion of any DEXes user base, they are critical to its healthy functioning.  In v2 we add standard functionality to show a liquidity pool provider their Asset Hub pool contributions, their USD value, the recent APR (based on 7d or 30d average activity), TVL, as well as easy access to add and remove liquidity to any pool.

![image](https://i.ibb.co/RNXhyBg/4113-sourabhniyogi-1720837177684.png)

#### Feature: Info Bubbles / Tutorial Bubbles

To give newbie/non-expert Polkadot users a walkthrough of Dotswap.org functionality, each major section will have a small tour.  This is intended to provide users with comfort with Polkadot’s multi chain peculiarities:

![image](https://i.ibb.co/pW8Ng7r/4113-sourabhniyogi-1720837420625.png)

#### Feature: Local Transfer features

To make it easy to send assets between addresses within Asset Hub, the basic transfer functionality of polkadot.js is encapsulated so that “everything can be done in one place”.

![image](https://i.ibb.co/drTjgV2/4113-sourabhniyogi-1720837381207.png)

#### Feature: Cross-chain to/from HydraDX + Moonbeam + Mythos

In v2, dotswap will be extended to support cross chain transfers to and from top defi parachains (Hydration [Substrate] and Moonbeam [EVM] + Mythos).  Initial viability testing has been conducted already for top assets for Hydration and Moonbeam and will be extended to support Mythos for the [upcoming airdrop](https://dune.com/substrate/mythos).

![image](https://i.ibb.co/gy9Sxbs/4113-sourabhniyogi-1720837632031.png)

#### Feature: Asset Admin and Create Pool

Historically, creators/minters of assets on Asset Hub have had to use polkadot.js to create new assets and set up new pools.  In v2, dotswap.org will be extended to support all major methods:
* assets.create - a user can create a new assetID
* assets.setMetadata - a user can set the name, symbol and decimals of an assetID
* assets.setTeam - a user can set the issuer, freezer, admin an assetID
* assets.mint - if an issuer, the user can mint some amount of an assetID to any beneficiary
* assets.burn - if an admin, the user can burn some amount of an assetID
* assetConversion.createPool - the user can create a pool for assets where there is no existing pool, and the user has at least some of that asset

For each of the above operations, a dedicated modal will be provided for seamless interaction.  While this advanced feature is not for everyone, it is a significant feature of Asset Hub to be able to create new assets, pools and have them be fee-paying.

## Requested Funding / Budget 

We request 77,903 DOT (est $468.2K based on EMA7 $6.01) for Dotswap v1.x + v2.x through OpenGov with utility.batch in 3 payments: (see [preimage](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot-public-rpc.blockops.network%2Fws#/extrinsics/decode/0x1a000c130503000100a10f0001000b0035061495f203000101002c8feeab5bd9a317375e01adb6cb959f1fea78c751936d556fa2e36ede425a4700130503000100a10f0001000b00bfc98d30e503000101002c8feeab5bd9a317375e01adb6cb959f1fea78c751936d556fa2e36ede425a47019a7d5b01130503000100a10f0001000b0079ab90c1ec03000101002c8feeab5bd9a317375e01adb6cb959f1fea78c751936d556fa2e36ede425a47019cb46f01))

## Key Benefits of Dotswap.org

With OpenGov support of this development plan, Dotswap.org will:

* Provide a place for everyone (non-advanced traders) to swap/transfer/create their assets across the ecosystem, starting with Asset Hub and the Relay Chain but to Ethereum (via Snowbridge) and major parachains and then others
* Begin to set up a user-friendly destination for lightweight trading for major assets (DOT/USDT/USDC), parachain assets (e.g. MYTH), and user-generated assets

I have successfully conducted the 3 operations on Dotswap.org

(1) XCM Transfer: https://assethub-polkadot.subscan.io/xcm_message/polkadot-1f12ea359684b21088e11ff171efeae6967fa8eb

(2) Swap: https://assethub-polkadot.subscan.io/extrinsic/6482878-2

(3) Added Liquidity: https://assethub-polkadot.subscan.io/extrinsic/6482890-2

Kindly send 10 USDT to 12RC63G52VeBkLhPxgVcieMG7Fwr1Qwu4q5eKUwz7KvD3228 on Polkadot Asset Hub!

Feedback: Looks simple and good. My only concern is that it took over 4 minutes for the XCM transfer to go through after it was completed in Dotswap.org. Maybe provide a notification to let users know that XCM transfers may take time to show up.
