It cannot be uniswap
That's because uniswap doesn't support BSC
That transaction is really BSC
I believe my friend do my limit order on BSC
He told me it's pancake swap. Cancelling order means he got the money back
Sorbet was supporting the multiple chain. It's better if you shall visit the site. It was supporting some blockchains like ethereum , BSC, AVAX and polygon. I guess your friend was using this service to make limit order on BSC chain. It's not only working on uniswap or ethereum blockchains.
