- Blockchain losses jumped 46% YoY to $2.93B in 2025
- DeFi faced 126 attacks, while centralized platforms lost the most
- Ethereum suffered the highest financial damage at $254M
According to a recent report from SlowMist, the total blockchain losses in 2025 reached an alarming $2.935 billion, despite a decrease in the number of reported incidents compared to 2024. This represents a 46% year-over-year increase in losses, revealing that although attacks became slightly less frequent, they were far more financially damaging.
One of the most significant factors behind this spike was a single massive breach involving centralized platform Bybit, which lost $1.46 billion, accounting for nearly half of the year’s total. In fact, centralized entities recorded only 12 incidents, but their financial losses totaled $1.809 billion, underscoring how damaging a single attack on a major player can be.
DeFi Still Targeted Most Often
While centralized platforms bore the brunt in terms of value lost, DeFi platforms remained the most targeted. Out of around 200 total blockchain security incidents, DeFi accounted for 126 attacks (63%), resulting in approximately $649 million in losses.
This trend highlights an ongoing issue in the decentralized finance space — while protocols aim to eliminate intermediaries, their security models still lag behind, making them attractive targets for hackers and exploiters.
Ethereum Tops the List of Affected Blockchains
In terms of individual blockchain networks, Ethereum experienced the highest losses, totaling around $254 million. It was followed by Binance Smart Chain (BSC) with $21.93 million, and Solana with $17.45 million.
These figures suggest that popular blockchains with high activity remain in the crosshairs of attackers. As more value flows into these ecosystems, so does the motivation for malicious actors to exploit vulnerabilities — whether in smart contracts, wallet integrations, or cross-chain bridges.
