The DEX router and WPOL pair of a Polygon tax token
A Polygon tax token swaps its collected tax through one DEX router, set at deploy in the Polygon token creator. "Uniswap (Recommended)" is the Uniswap v2 router 0xedf606...077AD1. "Router 2" is SushiSwap's v2 router 0x1b02dA...997506. Some of the earliest Tokenry tax tokens on Polygon use QuickSwap's v2 router 0xa5E082...A678ff.
The token's deploy pair is that router's pair with WPOL, wrapped POL, marked as an LP pair from the start. A Uniswap v2 POL pool opened in the Polygon liquidity pool creator fills this pair only on a token with the default router. The pool creator also offers QuickSwap v2 and has no SushiSwap option. Swap Settings can switch the token to another v2 router; the contract then finds or creates that DEX's WPOL pair and marks it as an LP pair, and the old pair stays marked until you unmark it in LP Pools.
