Answer 2:
Unfortunately, there is no direct way to check if a transaction has been affected by a sandwich attack on Curve. However, there are some steps you can take to protect yourself from such attacks. First, always keep your slippage set to a low value, as this will increase the chance of your transaction being successful and not affected by a sandwich attack. Additionally, you can check Etherscan after submitting a transaction to see if it has been affected by a sandwich attack. If you suspect that you have been affected, you can contact the Curve team to investigate further.
