I mistakenly sent Busd from my Iopay wallet to Binance unknown that the chain is not on Binance.
Please how do I recover my Busd please help me 
Hello Johnson,
Thanks for writing in.
Sorry we can not do anything as the tokens already in Binance’s system, you can go to Binance’s customer service to request a refund.
Hope it works.
Best Regards,
