It's called Roger Bank. Its target customers are military members and veterans, but unlike USAA, anyone can open an acct. It also offers a 2% checking acct with no DD or debit card usage requirements.

Citizens Bank of Edmond is listed with Plaid, but you wouldn't be able to select this as an option since Roger accounts are completely separate, with it's own credentials.
The ACH limits if you were to push and pull directly with Roger are low.
This bank only has 2 branches, and is small, and could be overwhelmed if a lot of people were to sign up at once. And I might guess that the 4.89% APR equaling 5% APY wouldn't be able to be sustained. The last assets total listed here at Deposit Accounts was $399.5 million.
@Midas89, I've noticed that you post comments at doc pretty frequently. Which website do you like better, doc or this one?
The only thing keeping this site possibly helpful for someone is the comments section, as you know.
I think DoC is the better one. Not only can people search through the comments sections, there are still helpful articles posted regularly, on various subjects like credit card rewards and bank & credit card bonuses, and there's an updated very helpful page with a list of a lot of banks and their current rates. And they even have a page dedicated to Hub Accounts, which lists a lot of banks and their ACH limits (not all are accurate, but searching the comments can help to see if anyone posted possible changes). In my opinion, DoC is the better place.
