Advanced Security Testing

Last Updated: February 19, 2026
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"?

  1. Attack-Focused: Tests potential exploit scenarios
  2. Economic Reality: Validates incentive structures
  3. Multi-User: Complex interactions between actors
  4. Timing-Sensitive: Front-running, MEV, race conditions
  5. 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
