~snip~You can use dexcreener and filter base on the time the smart contract created. Dexscreener tracks all the newly created token smart contracts on every chain including the liquidity volume on the pool.
That is pretty good advice. I also use Dexscreener to track all purchases or track contracts created by new projects. Just need to filter it and everything will be caught. But there are also some new tools like Arkham Intelligence which can look at all transactions at their root, you should also give it a try. It is backed by binance and is a popular intelligence tool for tracking cryptos today
