I was explained that to find the pair contract on PancakeSwap, all that's needed to be done is go to the Factory contract of Pancakeswap on bscscan ( 0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73 ), find the getPair() function in the read section of the contract, and insert the addresses of each of the cryptocurrencies in the pair.

I did this for WBNB and BUSD:

  • WBNB contract address:

  • BUSD contract address:


and I got the following contract:

  • Obtained pair contract address from the getPair() function on the Pancake Factory contract:


So far so good. The obtained contract shows about 244 million dollars worth of WBNB and about the same in BUSD inside it's liquidity pool. However!!... I randomly online found that there is another pair contract on PancakeSwap for the same pair of cryptocurrencies (WBNB/BUSD):

And now I'm entirely confused. I previously thought that only one pair can exist on PancakeSwap for 2 cryptocurrencies, but apparently that isn't accurate.

My Question:

Doesn't PancakeSwap only allow one contract per a specific pair of crypocurrencies? In the case that it doesn't, which pair is getPair() in the PancakeSwap Factory deciding to give you if there is more than one possible answer? In the case that only one pair can exist, then how was I able to find two contracts for this pair?

you're looking at the different PancakeSwap contracts versions. Example:

PancakeRouter V1 - 0x05ff2b0db69458a0750badebc4f9e13add608c7f

PancakeFactory V1 - 0xbcfccbde45ce874adcb698cc183debcf17952812

PancakeRouter V2 - 0x10ed43c718714eb63d5aa57b78b54704e256024e

PancakeFactory V2 - 0xca143ce32fe78f1f7019d7d551a6402fc5350c73

And so the contract 0x58F876857a02D6762E0101bb5C46A8c1ED44Dc16 is the WBNB/BUSD pair living inside the PankcakeRouter V2 and the contract 0x1b96b92314c44b159149f7e0303511fb2fc4774f is the WBNB/BUSD pair living inside the PankcakeRouter V1. They're completely different pairs with different liquidity ( not so different, because of arbitrage traders ). Every version is somehow better than the previous, currently I just saw that V1 is not supported anymore ( the contract might still be live, but PancakeSwap removed it from their interface ).

And as we know PancakeSwap is a fork of UniSwap and UniSwap presented lately V3 with another set of good features. I'm not sure if PancakeSwap will follow V3.
