Bramblefield Yield
Auto-compounding yield aggregator.
Vaults deposit into third-party farms and periodically harvest and swap rewards back into the deposit asset. A keeper network triggers harvests; strategies can be swapped by a strategist role.

Risk factors
HighGovernance RiskProfile analysis
Instant strategy migration
A malicious or compromised strategist can migrate funds to a contract that withdraws them.
MediumEconomic SecurityProfile analysis
Harvest sandwiching
Predictable harvests with fixed slippage are profitable to sandwich.
MediumInfrastructure ResilienceProfile analysis
Third-party farm risk
Vault safety depends on farms outside the protocol’s control.
Recommendations
Governance Risk: 66 → 76
Timelock strategy migrations
Add a 48-hour delay and public queue for strategy changes.
+1.5
→ 71.7
Economic Security: 70 → 78
Oracle-bounded harvest swaps
Set minimum output from an oracle price rather than a fixed tolerance.
+1.2

- FailStrategy swaps. Strategist can migrate funds to a new strategy immediately.
- CautionHarvest slippage. Reward swaps use a fixed 2% slippage tolerance.
Governance exposure
High
A 2-of-3 strategist multisig can move all vault funds into a new strategy without delay.
Operational resilience
Adequate
Keepers harvest on a schedule; no public monitoring of strategy changes.
