Shakeeb Ahmed stole over $12 million from Nirvana Finance and a DEX thought to be Crema Finance. Shakeeb Ahmed, a security engineer who stole over $12 million from two different decentralized cryptocurrency exchanges (DEXs) built on Solana, was sentenced to three years in prison and three years of supervised release by a federal judge on Friday. Ahmed was arrested last year on wire fraud and money laundering charges, after federal officials alleged he stole $9 million from a DEX built on Solana – which appears to be Crema Finance. He pleaded guilty to one count of computer fraud in December.
