UniswapLP Polygon mainnet - 'Token not supported' error

[fengtality]

Original issue: hummingbot/hummingbot#6099

--
Whatever I do on Polygon, I always get "Token not supported"

Steps to reproduce:

Created clean docker instance
Created gateway with 'gateway create'
Set up uniswap and uniswapLP with appropriate information and keys
Created strategy with uni_v3_lp on pair WMATIC-USDC
"start"
Release: latest / 1.12.0

log snippet:

While gateway create is now deprecated, the error message above seems to indicate that Hummingbot could not resolve the WMATIC symbol.

I confirmed that Gateway can resolve the WMATIC symbol via Postman:
.

I'll check if this works in Hummingbot later.

Latest development 1.14.0 Issue reproduced

Noticed that on uniswap WMATIC token will be placed as MATIC-USDC

Also noticed that bot mentioned WETH-USDC as the non-active market for uniswapLP-polygon-mainnet
However this market exists on the exchange

[nikspz]

Same issue (Token not supported) testing other pairs (UNI-USDC)

p.s. for the note: was able to trade UNI-USDC using amm_arb strategy

@nikspz Can you still reproduce this issue?

[nikspz]

Yes, reproduced on dev-1.17.0

logs_unilppolygondev117.log
UniswapLP polygon mainnet WBTC-USDC - Token not supported error

logs_uniswlpwmaticusdc.log
UniswapLP polygon mainnet WMATIC-USDC - Token not supported error

Got trades on WMATIC-USDC using amm_arb before testing uniswapLP

I think UniswapLP does not support Polygon yet. I was looking at the code, and it seems that UniswapLP is not handling the 'Polygon' chain.

https://github.com/hummingbot/gateway/blob/main/src/connectors/uniswap/uniswap.lp.helper.ts#L38

You can notice that in uniswap.ts, it is being checked if it's Ethereum; otherwise, it will be Polygon.

I'm trying to fix this, but I think I'll spend some time testing to make sure everything is running smoothly.
