No need create your own token list of USDC, WETH, etc...

what for this? If you want create enum with supported chains - do it.

Why you have 2 addLiquidity functions? slippageTolerance - not use anywhere.

this imports not use in code. We have strict rules in our project, it will not even compile with such imports and functions.

why if user want work with one token we must fetch his balances for all supported tokens?

we have 1-3 notify in execute functions
You have -
marketSwap.ts: 8 occurrences
getSwapsLiquidity.ts: 14 occurrences
getPerpsLiquidity.ts: 14 occurrences
closePosition.ts: 12 occurrences
getPerpsLiquidity.ts (leverage folder): 14 occurrences
getAllOpenPositions.ts: 18 occurrences
getPosition.ts: 17 occurrences
claimRewards.ts: 3 occurrences

Here maybe it's correct, because all info which goes in toResult - going through AI and it can be cut or modified, but in notify you can convey immutable data to user. But no need such notify quantity in execution functions.

you already check chain. currentNetworkContracts can't be undefined. You have a lot such redundant checks throughout all project.

Uses 18 decimals. Defaults to "0" if not specified. - what for? Use must specify token amount and inside functions you must handle decimals. Do not leave this for AI

do not do this. If you need specific tokens - it's ok. But not reassign WS, USDC, Anon. We already have our token list https://github.com/RealWagmi/heyanon-tokenlist
