Lack of nonReentrant Protection in Reward Functions

viveksh0062

Description

  • Functions like attendPerformance() and redeemMemorabilia() involve reward or mint logic. If implementation lacks nonReentrant, attackers can re-enter during token transfer/mint.


Risk

Impact:

  • Double reward claim

  • NFT duplication

  • BEAT token inflation


Recommended Mitigation

Mention reentrancy protection requirement in interface (@dev Must be nonReentrant). Enforce using OpenZeppelin's ReentrancyGuard in implementation.
