$500 is required to open the acct and receive interest; there's no minimum balance requirement. You can name 1 beneficiary. The biggest drawback to me is that you can only link a single FI to your acct.
Credit for this find goes to Kent Jamison who has his own excellent website called Deposit Quest. Every Friday he posts his own list of the top 20 highest yielding savings and MM accounts. I beat him to Climate First Bank's 5% business MM account though! You won't find that one posted at DoC or anywhere else on the internet. If you're interested, I've also included a link to Deposit Quest.
