Yes it's a microfinance bank fully registered under the CBN, that's my primary bank after I dumped Fidelity bank last year September, I've been using it for almost close to a year now so I can confirmed that Kuda is the safest place to be. Be your own bank is what kuda operates unlike the other banks. The signup might be slow due to high traffic so just dey try as long as you dey fill in the right information e go sign you up. If your case na verification code then the issue is from your network server, try use another sim or wait and keep trying.
