@keeganquigley like we discussed earlier :)
apologies for the delay, can you please review? thank you

We plan to store all the assets including all the parachain assets like HDX,GLMR as foreign assets at Polkadot Asset Hub.

https://wiki.polkadot.network/docs/build-integrate-assets#foreign-assets

Foreign assets are those assets in Asset Hub whose native blockchain is not Asset Hub. These are mainly native tokens from other parachains or bridged tokens from other consensus systems (such as Ethereum). Once a foreign asset has been registered in Asset Hub (by its root origin), users are enabled to send this token from its native blockchain to Asset Hub and operate with it as if it were any other asset.

I will update the proposal with above info for better clarification. Proposal updated with above info

I have added some more architecture diagrams in Project Details -> Core Components section and some other clarifications in the proposal.
Please let me know if any further clarficiation required, more than happy to explain or add anything :)

@keeganquigley thank you for your response.

Could you perhaps make a brief comparison to Chain Flip and Squid Router, and how these projects differ?

Hey these are cross chain DEX's which help swap across blockchain networks like MoonBeam <-> Ethereum and other Ethereum L2s outside of Polkadot. I mentioned it as an example to highlight the importance of cross chain solutions.
I will clarify this in the proposal.

Also, do you foresee any uncertainties related to Plaza's ongoing development? Anything that might need to change along the way?

Currently I dont think so. In our development scope we have added only for Polkadot Asset Hub DEX and Hydration DEX which doesn't involve any smart contracts yet. But down the road we have to figure out on how to integrate smart contracts, which is beyond the scope of development roadmap proposed.

also some updates on our current Development Status

Still in development, we plan to iterate it further :)

I recently made a huge swap on Hydration and ended up paying high fees. A similar transaction on StellaSwap (Moonbeam) would have cost much less in fees. This highlights how a DEX aggregator can simplify the process by fetching the best rates across the ecosystem. :)

@muddlebee I don't believe you've gone through the KYC/KYB process yet. While waiting for further reviews, could you please complete either KYC verification (for individual check) or KYB verification (for legal entity check, if any). Thanks!

@keeganquigley I have completed my individual KYC. We don't have any legal entity as such.

@muddlebee just out of curiosity—did you really pay over 28 DOT in fees for a swap on Hydration? That sounds unusually high. Do you know what caused it? I’ve never encountered trading fees anywhere near that level, and to my knowledge, their pools typically yield around ~0.3% APR, so I’m quite surprised.

In the meantime, I’ll be reviewing your proposal in detail and will provide additional feedback soon.

ahh yes, little less than that actually. The screenshot is after I made the swap and realized where the rest of my DOTs went. The reason for high trading fees is due to

Dynamic Fees during Increased Volatility
Protocol fees are dynamic and adjusted based on the current market volatility. If prices in the Omnipool are volatile, each swap will incur higher Protocol fees

Hi @muddlebee. Sorry for the long wait. I asked our legal team for input, and they asked me to verify that you are not building a DEX yourself, but an aggregator. I can see that this is the case, but just to make sure, is this on your roadmap at all?

Otherwise happy to support!

Hi @semuelle. No worries, and thank you for following up! We are not building a DEX, nor is it on our roadmap. Our primary goal is to serve as a hub for parachain DEXes or a DEX aggregator.

Hey @muddlebee
thanks for your application.

Different from the similar projects in the ecosystem that you listed I saw Kheopswap which is not focussed on pooling assets themselves or being limited to a single chain. It's also open source and has been retroactively funded via OpenGov. Do you think that it would be possible for you to reuse a lot of it's code? To my understanding there is a lot of overlap in the features between your project and Kheopswap. Maybe this could both reduce your development work and the price of the grant.

Otherwise I'm fond of your idea and I would like to see it happening. Please let me know your thoughts here.

Best,
Piet

Hey @PieWol thank you for reviewing.

Kheopswap is a DEX only for Asset Hubs(Polkadot and Kusama) and my use case is a DEX aggregator to find optimal routes for asset swaps from any of the DEX'es like Asset Hub or Parachain DEX'es like hydration or moonbeam.

Do you think that it would be possible for you to reuse a lot of it's code? To my understanding there is a lot of overlap in the features between your project and Kheopswap.

for our DEX aggregator we will using the AssetConversion/Assets pallets exposed by the Asset Hub's runtime to get pool liquidity data, asset conversion which I believe must be used by Kheopswap as well. That's the only overlap I could think of.
