Here’s your roundup of this week's onchain insights. Highlights: Behavior Filters Based on First-Seen Transaction Frequency Chart Query Parameter Redaction Sticky Referrer Tracking Reading List 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.
