April 2026 Changelog: Tax Information and Chart Builder

April brings tax collection controls for affiliate payouts and the biggest Chart Builder update yet with new chart types, metrics, and a public API.

Features

Tax Information

You can now require affiliates to submit tax documentation before they receive any payouts, helping you stay compliant with tax reporting obligations as your program scales.

• Affiliates must submit a W-9, W-8BEN, or W-8BEN-E through the affiliate portal before they can claim any rewards.
  
  
• Each affiliate's tax status is visible at a glance: Approved, Submitted, Expired, Revoked, or Not submitted, with a filter to segment by status.
  
  
• Submissions can be reviewed, approved, or revoked at any time. Revocation blocks the affiliate until they resubmit.

Chart Builder: KPI Cards, APR, and New Metrics

The Chart Builder receives its biggest update yet, with a new chart type, six new metrics, and a public API.

• KPI Cards: A third chart type alongside Line and Bar. Each card shows a single aggregated number for the selected period and appears at the top of your dashboard in rows of up to three.
  
  
• APR metric: Track historical APR across up to five conversions simultaneously, and combine it with TVL on a shared chart with independent scales.
  
  
• User metrics: Track average tokens paid per user, unique users rewarded, unique users converted, and unique referrers earning. All saved charts and their data are accessible via API using your project API key.

Improvements

Affiliate Management

The affiliate dashboard gets two major additions this month.

Tiers

When approving an affiliate application, the affiliate is placed into a tier with a configurable Protection Period. Each tier has its own detail screen where you can manage members, toggle manual approval, and extend or remove protections.

Filtering and Segmentation

• Filter affiliates by their tier status: Members, Candidates, or Lapsed.
  
  
• Segment by the number of referred users active in a given time window, for example, affiliates with between 10 and 20 referred users active in the last 30 days.
  
  
• New regions are now available in the affiliate application form: CIS, Georgia, Sao Paulo, South Africa, and EU aggregate.
  
  

Activity Log
The Activity Log tab in Settings gives you full visibility into your project's history. See every change made over time, who made it, and when, with filters by action, entity, user, or date range.
