How Bitfinex Lost—and What It Means for DeFi Users

Bitfinex’s loss was a centralized-exchange custody failure, not a demonstrated DeFi smart-contract failure. An intermediary lost control of assets, making the distinction between platform and user control crucial for every asset holder today. Bitfinex said in its security-breach notice that it had discovered an unauthorized access event and halted digital-token withdrawals while it investigated, establishing that the initial disruption was a platform incident rather than an on-chain protocol governance decision.
