Seer - create liquidity pool

[gabrielfior]

After market is created using MarketFactory, we should create an uni-v3-like liquidity pool (ERC20 outcome token x collateral, normally sDAI).

• Create functions for creating a new pool with erc20/collateral tokens in Uniswap v3 (due to higher liquidity than Swapr)
• Add new contract (UniswapV3Pool) to PMAT (note that we will not buy/sell directly on Univ3 but rather through cow, so refrain from writing methods to swap here)

[greenlucid]

But, Uniswap v3 is not available in Gnosis Chain, is it? Which might be why Seer is using Swapr.
Also I was told that Cow indexes only tokens with >100_000 units in total balance, and that caused issues with Seer in small markets (which made Seer not have an Order Book mplemented and just rely on AMM)
Can @xyzseer provide more context?
I think none of this was an issue before because Omen has its own AMM contracts

afaik there's a uniswap deployment on gnosis but it's not officially integrated on the frontend (see Uniswap/sdk-core#89)

what green mentions about the 100k limit is also true, for example this market https://seer.pm/#/markets/100/0x43d881f5920ed29fc5cd4917d6817496abbba6d9 has two tokens

• HARRIS2024 (0x68984a7d283ff918e530368e6aaad1fc2af88692) has a swapr pool with 140k and can be traded on cowswap
• TRUMP2024 (0x6b8c2ae8dba895620475259e95377fde08fbf02a) has a pool with 53k and cowswap says this token is unsupported

Updating my understanding here:
-> Creating liquidity pools occurs outside of Seer
-> Seer "finds" markets through this function useAllOutcomePools (link)
-> We could use SwaprV3 or Uni v3 (deployed recently on Gnosis chain)

Swapr V3
-> To be clarified what the easiest way is to interact with it - Seer UI uses Swapr SDK (link), no Python integration available (would need to write logic from scratch)

Uni V3
-> Python client exists (functionalities include createPool, createPosition, make trade, etc)

@gabrielfior I interacted with some market on Seer using CoW previously. What are the limitations there (if any except for 100k threshold)? Would we support a reasonable part of Seer markets if we are CoW-only? (because for CoW we already have some integration in PMAT and Martin talked about some improvement being made there, so we could just wait it out)

From the prev comments, I thought cow didn't support small markets, however it seems that now it does (see link below, pool contains < 100k tokens and still Cow supports swaps)
https://app.seer.pm/markets/100/0x7d72aa56ecdda207005fd7a02dbfd33f92d0def7?outcome=YES

So I will create a market manually (with aprox 10 xDAI) and check if Cow is able to solve that. I will report back here.

Update - cow is able to find the tiny pools I created for the test market. Proceeding under the assumption that cow integration suffices for the betting interaction.
