India’s CBI arrested Ayush Varshney, co‑founder and CTO of Darwin Labs, accusing the firm of providing technical infrastructure for the GainBitcoin Ponzi scheme. Authorities say the probe involves thousands of victims and cryptocurrency worth large sums, calling the arrest a major breakthrough.

On March 11–12, 2026 the Central Bureau of Investigation detained and then arrested Ayush Varshney, co‑founder and chief technology officer of Darwin Labs, as part of a long‑running probe into the GainBitcoin crypto fraud alleged to have swindled investors across India and abroad. Officials say Darwin Labs supplied the backend systems and technical services that powered trading interfaces and wallets used in the scheme; investigators claim the operation drew in thousands of retail investors and involved proceeds measured in thousands of crores of rupees. Varshney was intercepted at Mumbai airport and taken into custody amid coordinated evidence collection and questioning. Indian outlets described the move as a significant development in one of the country’s largest crypto Ponzi probes, with investigators pursuing asset tracing, exchange records and international cooperation to recover funds. Prosecutors have indicated further arrests and asset identification efforts may follow as the CBI seeks to map the full network behind GainBitcoin’s recruitment, payments and technology stack.
