Hi. I found very little documentation or instructions about BinanceUS’s fiat withdrawal endpoint. When I tried using the endpoint, it seems like ACH withdrawals do not work and using the Silvergate Exchange Network (SEN) is required? Attempting to withdraw to an ACH paymentAccount yielded “HTTP Response error: 400. {“code”:-9000,“msg”:“not bind sen”}”. There is no documentation about how to setup SEN with your BinanceUS account or if it’s even possible. Also, I feel like most customers use ACH or Wire Transfers for withdrawals and SEN isn’t used or mentioned anywhere else on the website.

If so, is it possible for ACH withdrawal support to get added to the BinanceUS API? For reference, Bittrex and CoinbasePro support this in their api’s, and it would be very useful if Binance.us did too.
