Echo Protocol Hacked: Admin Private Key Compromised, Attacker Mints 1,000 eBTC and Launders 384 ETH
Monad-based DeFi protocol Echo Protocol was hacked after an attacker gained access to the admin private key, minting 1,000 eBTC (~$76.7M). Through a series of cross-chain moves, 384 ETH (~$820K) ended up in Tornado Cash. SlowMist founder Yuxian attributed the breach to a single-point private key compromise, not a smart contract bug.
