Abstract

Live streaming platforms increasingly embed payments into the interaction loop. In these systems, payment confirmation latency is not merely a back-end performance metric but a front-end UX variable that shapes user behavior, trust, and retention. This paper introduces a novel invention candidate - the Latency-Elastic Trust Window (LETW) - a control layer that computes a per-session latency budget, adapts UX feedback, and enforces jitter-aware thresholds to protect conversational rhythm. We model confirmation latency as a behavioral driver in WebRTC streaming, quantify its effect on conversion and engagement, and propose a telemetry-driven framework to manage latency thresholds. We combine a hazard model with a behavioral elasticity curve and present simulated, calibration-based results that mirror real-world response patterns. Our findings indicate that latency beyond two seconds materially reduces tip completion and repeat engagement, and that latency variance is as important as mean latency. We further formalize the LETW as a patentable UX governor that maps network conditions to user-facing modes, and we provide operational thresholds for engineering teams to enforce trust-preserving payment feedback.
