UniswapLP Polygon mainnet - 'Token not supported' error about gateway

[johna1203]

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.

https://github.com/hummingbot/gateway/blob/main/src/connectors/uniswap/uniswap.ts#L61

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

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

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
