Asset Hub: Asset Conversion and Swap Weight Trader by muharem · Pull Request #218 · polkadot-fellows/runtimes

muharem · 2024-03-05T17:46:20Z

Asset Conversion instance for Polkadot Asset Hub and XCM Swap Weight Trader for both Asset Hubs.

TODO:

update treasury account when this PR merged - Treasury Pallet Account as destination for XCM fees on System Parachains #191
define account deposit for pool assets, liquidity withdrawal fee, pool setup fee;

muharem · 2024-03-06T11:54:23Z

@joepetrowski need your help to set there parameters:

account deposit for pool assets
pool setup fee
liquidity withdrawal fee

I think we can have 0 for 1. if 2. is not 0. In Kusama both set as 0.

…ion-and-weight-trader

joepetrowski · 2024-03-07T14:41:07Z

We decided to set both as 0 because all pairs must be against DOT, so the number of pools is limited by the number of assets linearly (one asset, one pool) as opposed to quadratically (any-to-any pools, N^2). Since asset creation requires a deposit, we decided that it would reasonably include having a pool fot it.

Liquidity withdrawal fee can also be 0, that only needs to be nonzero if any-to-any pools are allowed.

Some minor nits but looking good. One question, XCM V3 is used throughout, but since SDK v1.7.0 we are on XCM v4. Do these types need to be updated here?

I didn't look too closely at the bridge test cases. Would be good if @acatangiu can check those.

Link an issue?

I am also collecting similar TODOs here: #186

Reviewed tests and all of them look good! Before finishing full review, I had an early question: are we adding the DEX/pools on both Kusama and Polkadot at the same time? I was under the impression Polkadot was to get it one release later than Kusama..

This has been on Kusama for like 6 months :)

Ok, sorry, I posted the early question too early (before even looking at the runtimes code) :))

@joepetrowski I have updated the deposits/fees. Plus for PoolAssets in Kusama Asset Hub, AssetAccountDeposit is updated from 0 to the same amount as in other Assets instances

what about the AssetHubKusama? It uses pallet_asset_conversion::WithFirstAsset, should we change it there also?

only possible with migration, which will be available for the next release

what about AssetHubKusama? There is still:

type PoolSetupFee = ConstU128<0>; // Asset class deposit fees are sufficient to prevent spam

shouldn't we change AHK also?

set it as in polkadot

when merged, I will regenerate weights as a part of #223

@acatangiu can you please help with review

+	type MetadataDepositBase = ConstU128<0>;
+	type MetadataDepositPerByte = ConstU128<0>;


DQ but why are they zero?

Only the system (the AC pallet) can actually create assets within this instance of Assets, so only the system itself could actually create any assets and add any metadata.
