|
## 🎯 Key Features
|
|
|
|
### 🐋 Automatic Token Funding
|
|
|
|
The framework automatically funds test accounts by:
|
|
|
|
1. 📋 Looking up whale addresses from the registry
|
|
2. 🎭 Impersonating whales on the fork
|
|
3. 💸 Transferring tokens to test accounts
|
|
4. ✅ Verifying balances
|
|
|
|
### 🔮 Enhanced Oracle Shocks
|
|
|
|
Oracle shocks attempt to modify Chainlink aggregator storage:
|
|
|
|
1. 🔍 Resolve aggregator address from feed name
|
|
2. 📊 Read current price and round ID
|
|
3. 🧮 Calculate new price based on percentage delta
|
|
4. 💾 Attempt to modify storage slot (with fallback warnings)
|
|
5. 📝 Log detailed information for verification
|
|
|
|
### 🎲 Fuzzing Support
|
|
|
|
Fuzzing runs scenarios with randomized parameters:
|
|
|
|
- ✅ Amounts vary by ±20%
|
|
- ✅ Oracle shock percentages vary within ranges
|
|
- ✅ Fee tiers randomly selected
|
|
- ✅ Slippage parameters varied
|
|
- ✅ Each iteration runs on a fresh snapshot
|
|
|
|
### 🔌 Multi-Protocol Support
|
|
|
|
The framework supports multiple protocols:
|
|
|
|
| Protocol | Features | Status |
|
|
|----------|----------|--------|
|
|
| Aave v3 | Lending/borrowing | ✅ |
|
|
| Uniswap v3 | Swaps | ✅ |
|
|
| Compound v3 | Lending/borrowing | ✅ |
|
|
| ERC20 tokens | Approvals, balances | ✅ |
|
|
|

## 📝 Notes
|
|
|
|
### 🔮 Oracle Manipulation
|
|
|
|
Oracle storage manipulation is complex and may not work on all forks. The framework attempts the manipulation and logs warnings if it fails. For production use, consider:
|
|
|
|
- ✅ Using mock oracles
|
|
- ✅ Deploying custom aggregators
|
|
- ✅ Using Tenderly's simulation capabilities
|
|
|
|
### 🐋 Token Funding
|
|
|
|
Token funding relies on:
|
|
|
|
- ✅ Whale addresses having sufficient balances
|
|
- ✅ Fork supporting account impersonation
|
|
- ✅ RPC endpoint allowing custom methods
|
|
|
|
If funding fails, accounts can be manually funded or alternative methods used.
|
|
|
|
### 🍴 Fork Requirements
|
|
|
|
For best results, use:
|
|
|
|
- ✅ Anvil (Foundry) for local forks
|
|
- ✅ RPC endpoints that support custom methods
|
|
- ✅ Sufficient block history for protocol state
|
|
