Echo Protocol Private Key Leak: $821.70K Reported Loss

·Historical incident record

Incident Overview

Echo Protocol’s eBTC on Monad was compromised due to an admin private key leak. The attacker granted themselves minting rights, minted 1,000 unbacked eBTC (~$76.7M nominal value), deposited 45 eBTC (~$3.45M) as collateral into Curvance to borrow ~11.29 WBTC (~$867K), bridged it to Ethereum, swapped for ETH, and sent ~384 ETH (~$821K) to Tornado Cash. The remaining 955 eBTC stays under attacker control, posing ongoing depegging risk.
