LayerZero is an omnichain messaging layer that makes protocol upgrades optional via Library upgrades so apps opt into new code rather than having their security clock reset; upgrade keys cannot force a change. A second defense, pre-crime, forks the involved chains during the inter-chain delivery window, runs invariants (eg total supply equals 1,000,000,000; deposits equal withdrawals like 50,000 in/out) and blocks delivery if checks fail. Launched silently in April/May and live protecting Stargate after industry hacks (Ronin/Harmony/Wormhole) exposed upgrade and messaging risks.
