Implementation Summary: CreateStreamModal Field Labels & Helper Text

Issue: #216
Status: Ready for Review
Type: UI/UX Design + Implementation
Date: May 31, 2026

Overview

Successfully implemented clarified form field labels and contextual helper text for the CreateStreamModal component (Step 2: Rate & Schedule). This update addresses user confusion by providing inline unit indicators, tooltips with detailed explanations, and improved helper text for the accrual rate, cliff, and duration fields.

What Changed

🎨 User-Facing Changes

Before:

Stream rate field lacked unit indicators (users didn't know if it was per day, week, or month)
No contextual explanations for "cliff" concept or how accrual works
Generic helper text didn't provide sufficient guidance
High error rate due to unclear input expectations

After:

✅ Inline unit badges: "USDC / day" and "days" clearly visible in input fields
✅ Info icon tooltips: Detailed explanations for stream rate calculation, duration, and cliff concepts
✅ Improved helper text: Clear, actionable guidance for each field
✅ Fully accessible: WCAG 2.1 AA compliant with keyboard navigation and screen reader support
