Select pools
Choose Uniswap Swap and up to three pools across your selected chains. The picker combines v2, v3, and v4; check the version and pair before selecting. v4 pools use a pool ID rather than a pool contract address.
Use the version filter if you want only one Uniswap version. A pool selection watches that pool’s swaps, not every trade involving either token.
If liquidity moves to a different pool or version, update the selected pool. Combining versions in one picker does not automatically follow a pool migration.
Understand the amounts
token_in and token_out describe swap direction; amount_in and amount_out are the corresponding positive amounts. Price is token1 per token0, and price_inverse expresses the opposite direction.
USD value and fee information may be unavailable. Inspect a concrete example before choosing filter units or writing a price message. Do not describe a swap’s execution price as a market-wide token price.
