DeFi’s old hack vectors are fading – But the new risk can hit six chains at once

- DeFi isn’t dead; it’s just evolved. Losses crashed 80% since 2022 because we finally fixed the stupid stuff: bridge hacks, flash loans, and private key leaks are now yesterday’s news. The industry learned to patch the low-hanging fruit. But don’t pop the champagne yet. The new threat is multi-chain code reuse. A single logic bug in a protocol deployed across Ethereum, Base, Arbitrum, Polygon, OP Mainnet, and Sonic can drain six chains simultaneously. Remember Balancer’s $128M drain? That was eleven audits failing to catch one arithmetic flaw. We traded billion-dollar bridge hacks for systemic, cross-chain logic exploits. It’s safer, sure, but now one typo takes down half the ecosystem. Bear market merch incoming? More like "multi-chain audit fatigue" tees. Stay sharp, or get drained.
