No, not that we are aware of.
The ACH pulls actually are going to Prime Trust, our custodial partner who deals with many different types of custodial solutions. As a result, it is not so obvious to your bank that the funds are being used to buy Bitcoin.
In regards to wiring, there have been a few banks that have struggled to wire funds to Nano Banc, our partner bank. We highly recommend using Chase Bank to wire funds, if you already have an account open with them, as their online wiring form is easy and their customers have had smooth experiences wiring funds to fund their Swan account.
