Coinsbuy Exchange Drained of $8 Million in Coordinated TRON-Ethereum Attack

The $8 million drain of Coinsbuy across TRON and Ethereum marks the latest case where a single on-chain footprint ties two blockchain networks into one attack narrative.

According to the original report, forensic analysis has connected the exploitation of the exchange to one actor, with the stolen funds primarily routed through the non-custodial platform FixedFloat.

The attack, which unfolded early on 10 August 2026, siphoned assets from wallets operating on both TRON and Ethereum. On-chain data shows the attacker rapidly dispersed tokens into a chain of intermediary addresses before funnelling them toward FixedFloat swap contracts.

The ability to link the two disparate chains in real time suggests a level of orchestration that is becoming more common as cross-chain infrastructure grows.
