• CríticoEXPLOIT: Re-entrancy risk — external call before state update, no guard

  beacon/light/sync/update_sync.go:149

  Verify the contract follows the Checks-Effects-Interactions pattern: (1) CHECK conditions first (require balance > 0), (2) UPDATE state (balance = 0), (3) INTERACT externally (call{value:}). Use OpenZeppelin ReentrancyGuard modifier on all functions making external calls. The nonReentrant modifier should appear on the function.
