India's Central Bureau of Investigation (CBI) intercepted and arrested Ayush Varshney, co-founder and CTO of Darwin Labs, at Mumbai airport as he attempted to flee to Colombo, Sri Lanka. The arrest followed a Look Out Circular issued after Varshney went into hiding. The case involves the Gain Bitcoin scam, one of India's largest financial frauds valued at over ₹20,000 crore (approx. $2.4 billion).
Darwin Labs: The Technical Backbone of the Fraud
CBI investigations reveal that Darwin Labs was not a peripheral player but the "technical backbone" of the entire scheme. Under Varshney's leadership, the firm built digital infrastructure that enabled the fraud, including the MCAP token — used to deceive investors when real Bitcoin supply dwindled in 2017. Other tools included a fake Bitcoin mining pool to simulate a legitimate business, a "Coin Bank" for moving digital funds, and the main website gainbitcoin.com, which lured victims.
The scam, initiated by the late Amit Bhardwaj, promised investors a 10% monthly return in Bitcoin for 18 months. In reality, it was a classic Ponzi scheme: early investors were paid with new deposits until the system collapsed.
Raj Kundra's Involvement and Asset Seizures
The scam's scale drew in high-profile figures, notably businessman Raj Kundra. India's Enforcement Directorate (ED) alleged Kundra received 285 Bitcoins from Bhardwaj for a mining project in Ukraine that never materialized. On February 20, 2026, a Mumbai court granted Kundra bail after a supplementary chargesheet valued his alleged holdings at over ₹150 crore. The ED previously attached assets worth ₹97.79 crore belonging to Kundra and his wife, actress Shilpa Shetty, including a flat in Juhu and a bungalow in Pune.
Shift in Law Enforcement Focus: Architects Now Targeted
This arrest signals a major shift: law enforcement now targets the "architects" who build the code, not just those who sold fraudulent investments. The CBI is expected to analyze data from Varshney's devices to track the 29,000 Bitcoins still missing. As international agencies cooperate to freeze digital wallets, this case will set new standards for crypto regulation in India. More arrests are anticipated as the investigation uncovers hawala transactions and global money laundering networks.
