BEST Onboarding Flow

We are just like OnlyFans except built for celebrities + mainstream influencers and their super fans. We will not allow explicit 18+ adult content. We are keeping things 'brand-safe'. So the question is do you all have a bona fide sign-up and onboarding flow for sellers (the talent in our case) and buyers (talent's super fans). Our app was just approved to the app store recently and we've been hard at it trying to get to this point but would love to see if anyone can share onboarding steps that have worked well for them either currently or in the past. Thanks!
