@vic-en can you take a look at this PR since you worked on PancakeSwap upgrade?

[vic-en]

@fengtality
These changes are not related to pancake v3 LP.
They're changes to the existing swap.
Nevertheless, I'll look before today ends.

@0xcodercrane
Just one comment for you, you can remove the router abi file as I see it's no longer used.

@fengtality
As mentioned earlier, this changes pertain to the swap funtionalities.
As it is, it integrates the latest smart router which allow swaps to automatically use v3 pools when available.
That being said, there's no funtionality to strictly use v3 pool only as available in uniswap code. So I guess further decision is up to you.

@vic-en routerAbi is required field of Uniswapish.
and for the functionality which allow swaps to use only v3 pools, i pushed the changes about allowed pool types. i believe we can use that function.

@vic-en @0xcodercrane @fengtality what about this pr, what else is missing to merge it?

[jellebuth]

We have been testing the implementation and noticed a 10x increase in RPC calls for price fetching. The free ANKR endpoint does not support price fetching for PCS V3 as there is a limit of 300/s and it is exceeded.

Please take a careful look into this before merging.

Could you please approve ci/cd run @fengtality ?

[0xcodercrane]

adding last fixes of unit test.

[cardosofede]

approved workflow run @0xcodercrane

[0xcodercrane]

approved workflow run @0xcodercrane

thank you. how can I see which tests are failing from ci/cd. Would you help me on that? @cardosofede

[0xcodercrane]

hey admins! anyone please approve the workflow run?

[fengtality]

@0xcodercrane Thanks - looks like tests are passing now. I'll review and address @vic-en's comment above shortly.

[fengtality]

Looks good - thanks for the addition of the subgraph connection - I can definitely see why this improves latency for price fetching.

@jellebuth Thanks for testing this PR. Does the change from Ankr to LlamaRPC as default provider fix your issues?

@0xcodercrane Requested changes:

Review the fields in pancakeswap.yml in the templates folder. If any are not used anymore after this change, please remove them from this file. This will let users know what options they have to modify how the connector works.

@vic-en I don't think we need to add an option for users to select only V2 or V3 pools, unless they request it afterwards.

[fengtality]

Actually, I will approve merge this PR in now, so that other outstanding PRs can update their dependencies. @0xcodercrane please clean up the Pancakeswap default configs template at your convenience.
