### **Behavior Filters Based on First-Seen**

Behavior filters now support First-seen relative time windows to make targeting much more precise.

Until now, behavior filters were limited to rolling windows ("did X in the last N days").

You can now anchor windows to each user's first-seen timestamp, so you can ask questions like:

*   Users who visited the Trading Competition page within 2 hours of their first session (attribute engagement directly to the campaign that brought them in).
    

*   Users who connected a wallet, deposited, and clicked "Enroll" within their first 24 hours (first-day activation funnel).
    

*   Users who came back to transact more than 7 days after first-seen (true returning users vs. same-session conversions).
    

Together these mean better attribution to specific campaigns, sharper onboarding activation analysis, and more targeted segments.

### **Transaction Frequency Chart**

A new transaction frequency chart on the Users page show you how often your users transact.

View the distribution of transaction counts per wallet to distinguish one-time users from power users, spot drop-off between first and second transactions, and target wallets by activity tier.

  

### **Query Parameter Redaction**

You can now strip sensitive query parameters before events are stored or sent.

Pass a list of query parameter names and the SDK redacts matching keys (case-insensitive) from event properties.

  

### **Sticky Referrer Tracking**

The Web SDK now keeps first-touch referrer sticky across an entire session, so internal navigation no longer overwrites the source that brought a user in.

This means cleaner channel reports, more accurate first-touch attribution, and no more "self-referral" noise from internal page-to-page navigation.
