Summary
India's largest cryptocurrency exchange, CoinDCX, has temporarily restricted new futures positions following a security incident at Binance, a key liquidity provider for the platform. According to CoinDesk, CoinDCX said on X that it had moved its futures market into "reduce-only" mode, citing "recent developments impacting a global liquidity provider." The exchange did not name the provider publicly, but a CoinDCX spokesperson told CoinDesk that it was Binance.
Under the restriction, traders cannot open new positions or increase the size of existing long or short bets. They may still add or reduce margin on existing positions, and open orders continue to execute. CoinDCX said deposits and withdrawals are functioning normally and that customer funds remain safe. The restriction is temporary and applies only to futures, though the exchange has not given a timeline for resuming normal trading.
CoinDCX aggregates a significant share of its futures liquidity from large global venues, including Binance, and its institutional materials describe systems that stream Binance order books for USDT-margined perpetuals and route activity accordingly. The exchange's futures market is small relative to global peers such as Binance and Deribit, however; its combined spot and futures volume over the past 24 hours was just over $1 million, according to CoinGecko.
Binance, the world's largest cryptocurrency exchange, reported a major security incident on October 29-30, 2026, with an estimated impact of about $6.3 billion in crypto assets. Early findings pointed to a compromised DevOps engineer's laptop that enabled unauthorized withdrawal transactions. Binance said there was no evidence of private-key leaks.
