Largest Crypto Exploits by Value

Comparing the Tectonic exploit's $9.2M to the biggest crypto hacks reveals a stark difference in scale, with some incidents involving hundreds of millions or even billions of dollars.

The top 3

  1. The Bybit $1.5 Billion Breach: In February 2025, Bybit experienced the largest crypto hack in history, losing an estimated $1.5 billion in Ethereum-based assets due to compromised third-party developer workstations and social engineering tactics that manipulated transaction processes.
  2. The Ronin Bridge $600M+ Exploit: In March 2022, the Ronin Bridge, which connects Axie Infinity's sidechain to Ethereum, suffered a hack where attackers stole 173,600 ETH and 25.5 million USDC, valued at over $600 million at the time, by compromising five of nine validator signatures.
  3. Poly Network $610M+ Exploit: The Poly Network suffered a $610 million exploit in August 2021, where an attacker used data manipulation to steal assets across Ethereum, BNB Chain, and Polygon, though most of the funds were eventually returned.
