MEW is a MyEtherWallet which can detect existing transactions and can also check on blockchains that have been set up, such as Ethereum, Binance Smart Chain, Polygon Matic, Avalanche etc.
If the OP needs a few dollars for transaction fees from the Ethereum network then it will definitely be a heavy burden because it is very expensive, but if the transaction fees from Binance Smart Chain, Polygon Matic, and Avalanche it will feel very cheap and just ask OP's friend who has gas costs. lol
