Switching to a WF HYSA

My wife and I have had a HYSA with Amex for a few years now and recently came to the conclusion that we should move our funds to somewhere else now with the rates dropping so low. I’ve been looking into Wealthront and from what I’m understanding the cash account is basically a HYSA. What’s interested me are the other options as well besides that but does anyone have some feedback as far as opening a joint account with Wealthfront? Any things to know? Also can anyone share with me a boosted rate referral code? Thank you!
