Solo, a privacy-preserving proof-of-humanity company, has integrated its human verification software development kit (SDK) into JellyJelly, a social video app built on Solana and co-founded by Venmo co-founder Iqram Magdon-Ismail.
The integration enables JellyJelly to verify that every account belongs to a real, unique person without requiring government identification or puzzle-solving challenges. Magdon-Ismail, who serves as CEO of JellyJelly and advisor to Solo, co-developed the SDK alongside the company.
AI Agents Passing CAPTCHA Tests
The partnership comes as artificial intelligence agents increasingly defeat traditional CAPTCHA systems. In an experiment, Solo's AI agent joined over 50 Discord servers and sent more than 500 messages without being identified as an AI. The agent successfully passed every CAPTCHA challenge and accepted terms of service through standard browsing and clicking, without custom exploits.
Solo's analysis suggests this reveals a fundamental weakness in CAPTCHA technology. Traditional challenges test whether a visitor can solve puzzles, but capable AI agents can solve the same puzzles humans can. Harder tests add friction for legitimate users while failing to verify that a human controls the account.
Verification Technology Details
Solo's verification process begins with a facial scan from a standard smartphone camera. The company converts the scan into a biometric representation and encrypts it on the device using fully homomorphic encryption (FHE), a technique that allows systems to work on data without decrypting it. This approach lets Solo compare encrypted biometric data against existing records without exposing the underlying information.
Users do not need special hardware or government-issued identification, and raw facial images are not stored. Applications using the SDK receive only a verification result, not access to biometric data.
Broader Applications
The same SDK can be integrated into gaming platforms, payment services, and other applications requiring duplicate account prevention or separation of real users from automated activity. JellyJelly, which allows users to share short videos and send cryptocurrency payments, faces particular challenges from AI-generated video and automated accounts.
Solo is backed by Draper Associates, the venture firm founded by Tim Draper, which led a $1 million funding round in March 2025. The company was also selected for cohort 5 of the Solana Incubator.
