Harassment and abuse
Unaccountable users creating toxic environments lead to user churn and reputational damage for your platform.

FAQ
Common questions
How is Trust & Safety different from Fraud Prevention?+
Fraud Prevention focuses on stopping direct financial loss (e.g., payment fraud). Trust & Safety is broader — it's about protecting the user experience and platform integrity from non-financial harm like scams, spam, and abuse, which ultimately protects your brand's value.
Will identity verification scare away my users?+
Not with a seamless process. Our flow takes less than a minute and can be presented as a benefit — a commitment to user safety. In our experience, legitimate users appreciate platforms that take security seriously.
What does the "Verified" badge look like?+
The badge design is flexible and can be customized to fit your brand. It signals to other users that the profile has been verified by a trusted third party, increasing confidence in interactions.
Does this work for both sides of a marketplace?+
Yes — you can require verification for buyers, sellers, service providers, or all parties. Configurable flows let you apply different verification levels to different user segments.
