title: Commission on smart contract execution (cut on amount transfered)
body: <p>I'm sorry if it's the wrong place but I was asking my self where in the smart contracts websites like PancakeSwap or UniSwap takes their cut (0.2 and 0.3% if I'm right).</p>
  <p>Willing to work with solidity and I didnt know if they just take their cut with a quick math and send it to their wallet or if there are other ways to do so.</p>
  <p>Thanks for you answers !</p>
