World ID 4.0 Launches with Tinder and Zoom Integration, Reaches 18M Verified Users

Gate News message, April 19 — Tools for Humanity, the startup behind World ID and chaired by OpenAI CEO Sam Altman, launched World ID 4.0 on April 19, expanding its biometric human verification system. The update introduces key rotation, which splits encrypted biometric data across multiple parties, and tiered verification options ranging from Orb iris scans to government IDs and selfies. World ID has reached 18 million verified users who have authenticated 450 million times since its 2023 launch.

World ID is now integrating with Tinder in the US, where verified users can display a verification badge, and with Zoom, where meeting hosts can require identity verification before participants join. The company also released a beta app for storing credentials.

The expansion is supported by venture funding and token sales, including a $65 million WLD token sale in March 2026 to fund ecosystem growth. WLD has declined approximately 97% from its March 2024 peak. A significant unlock event scheduled for July 23, 2026 could potentially double the circulating supply and create additional downward price pressure.
