Dego Finance

Hacked

DeFi · $DEGO · ✝ 2022

One leaked key, three chains drained at once.

Dego Finance was a cross-chain NFT and DeFi protocol. In February 2022 attackers compromised its private keys and drained roughly $10M across Ethereum, BNB Chain, and Cronos.

Peak: ~$10M stolen
Cause: Hacked
Year of death: 2022

☠️ Cause of death

Private keys controlling the protocol's deployer or treasury wallets were compromised by an unknown method, enabling multi-chain draining.

📓 Lessons left behind

—A single key compromise can span every chain you deploy to.
—Use multisig and cold storage for cross-chain admin keys.
—Rotate and compartmentalize keys across deployments.

🌱 The idea that survived

Multisig admin keys

Reinforced multisig and cold-storage custody for protocol deployer and treasury keys.
