Advanced Security Testing
Last Updated: January 13, 2026
Test Count: 25 advanced tests
Status: Production Ready
Overview
Advanced security tests go beyond basic functionality to validate real-world attack scenarios, economic gaming, and complex multi-user interactions.
Test Philosophy
What Makes a Test "Advanced"?
- Attack-Focused: Tests potential exploit scenarios
- Economic Reality: Validates incentive structures
- Multi-User: Complex interactions between actors
- Timing-Sensitive: Front-running, MEV, race conditions
- State Complexity: Edge cases and unexpected states

Security Impact
Attack Vectors Validated
Economic Attacks (8 tests):
- ✅ Flash loans cannot manipulate state
- ✅ Front-running is unprofitable (fees)
- ✅ Reward gaming prevented (time-weighted)
- ✅ Dilution attacks don't affect past rewards
Timing Attacks (5 tests):
- ✅ Last-second stakes don't steal rewards
- ✅ Blacklist is immediate (no timing window)
- ✅ Pause blocks all operations instantly
- ✅ Multi-block scenarios handled correctly
Gaming Attacks (7 tests):
- ✅ Stake cycling not more profitable
- ✅ Mass exits don't harm remaining stakers
- ✅ Dust attacks don't break accounting
- ✅ Tiny stakes still earn proportionally
Invariants (5 tests):
- ✅ Conservation of tokens maintained
- ✅ Sum of balances = total supply
- ✅ Earned rewards ≤ available balance
- ✅ Total staked ≤ token supply
Real-World Scenarios
Scenario 1: MEV Bot Attack
Setup:
- Whale prepares large buy transaction
- MEV bot sees transaction in mempool
- MEV bot front-runs with smaller buy
- Whale's transaction executes
- MEV bot tries to sell for profit
Test Result:
- ✅ Fees make front-running unprofitable
- ✅ Time-weighted rewards prevent gaming
- ✅ Same-block buy/sell restricted
Scenario 2: Last-Second Stake
Setup:
- Alice stakes 1M tokens for 29 days
- Attacker sees period ending
- Attacker stakes 10M tokens at last second
- Both claim rewards
Test Result:
- ✅ Alice earns ~100x more than attacker
- ✅ Time-weighted distribution works
- ✅ Gaming attack not profitable
Scenario 3: Reward Dilution
Setup:
- Alice stakes and earns for 15 days
- Whale stakes 90M tokens (massive)
- Alice checks if past rewards diluted
Test Result:
- ✅ Alice's past 15-day rewards protected
- ✅ Only future rewards are diluted
- ✅ Past earnings immutable
