# Uniswap V3

To know if it's a uniswap v3 contract before the drop goes live we can simply check through the contract.

First address: 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2

Second address: The token contract

Input section: Try 500, 3000 or 10000 when it returns a contract it's V3 when it doesn't return anything it isn't V3.
