Funding Your Account

I currently hold a UK based Revolut account that I want to hold USD in.
I want to fund the account using a bank transfer of USD from my brother’s account in Singapore to my UK Revolut account.
Is this possible, will there be any issues with funding my UK based Revolut account with a bank transfer from a foreign bank account not in my name i.e. in my brothers name.

Yes you will most likely trigger a money laundering flag and get a blocked account.
