🎯 CreatorCharmStrategyV2 - Production Ready

✅ What Changed from USD1/WLFI → CREATOR/WETH​

Token Replacements:​

Ratio Adjustments:​

maxSwapPercent30%5%99/1 ratio needs minimal swaps
Initial ratio~50/5099/1CREATOR-heavy pool
Price fallback7 WLFI per USD1100 CREATOR per WETHReflects 99/1 ratio

Interface Additions:​

✅ Added full IStrategy interface implementation:

  • isActive() → bool
  • asset() → address
  • getTotalAssets() → uint256
  • deposit(uint256) → uint256
  • withdraw(uint256) → uint256
  • emergencyWithdraw() → uint256
  • harvest() → uint256
  • rebalance() → void

New Features:​

✅ Single-sided CREATOR deposits - Handles 100% CREATOR input
✅ Auto-swap to maintain ratio - Swaps 1-5% CREATOR → WETH as needed
✅ Graceful WETH→CREATOR conversion - Withdrawals return only CREATOR
✅ Harvest tracking - Monitors profit over time

📊 How It Works - 99/1 CREATOR/WETH​

Initial Deposit (Empty Charm Vault):​

User deposits: 100,000 CREATOR

Strategy automatically:
1. Keeps 99,000 CREATOR (99%)
2. Swaps 1,000 CREATOR → ~10 WETH (1%)
3. Deposits both to Charm vault
4. Returns unused tokens to vault

Result: 99/1 ratio established

Subsequent Deposits (Vault has liquidity):​

Charm has: 990,000 CREATOR + 10,000 WETH (ratio 99:1)
User deposits: 50,000 CREATOR

Strategy calculates:
1. For 50,000 CREATOR, need ~500 WETH
2. Don't have WETH → swap 500 CREATOR → 5 WETH
3. Deposit 49,500 CREATOR + 5 WETH
4. Maintains 99/1 ratio

Result: Proportional deposit, ratio maintained

Withdrawal (Auto-convert to CREATOR):​

User withdraws: 10% of position

Strategy executes:
1. Withdraw 10% shares from Charm
2. Receive ~9,900 CREATOR + 100 WETH
3. Swap 100 WETH → ~10,000 CREATOR
4. Return ~19,900 CREATOR to user

Result: User receives only CREATOR (as expected by IStrategy)

🚀 Deployment Steps​

1. Deploy CreatorCharmStrategyV2:​

constructor(
    address _vault,          // CreatorOVault address
    address _creator,        // CREATOR token address
    address _weth,           // WETH address (Base: 0x4200000000000000000000000000000000000006)
    address _uniswapRouter,  // SwapRouter (Base: 0x2626664c2603336E57B271c5C0b26F421741e481)
    address _charmVault,     // CharmAlphaVault (deployed separately or 0x0)
    address _swapPool,       // CREATOR/WETH V3 pool (or 0x0 if not exists yet)
    address _owner           // Strategy owner
)

2. Initialize Approvals:​

strategy.initializeApprovals();

3. Set Charm Vault (if not set in constructor):​

strategy.setCharmVault(charmVaultAddress);

4. Set Swap Pool (if exists):​

strategy.setSwapPool(creatorWethPoolAddress);

5. Optional: Enable zRouter for gas savings:​

// Base zRouter (when available)
strategy.setZRouter(0x...);
strategy.setUseZRouter(true);

6. Optional: Enable auto fee tier discovery:​

// Base V3 Factory: 0x33128a8fC17869897dcE68Ed026d694621f6FDfD
strategy.setUniFactory(0x33128a8fC17869897dcE68Ed026d694621f6FDfD);
strategy.setAutoFeeTier(true);

7. Add Strategy to Vault:​

vault.addStrategy(strategyAddress, allocationBps); // e.g., 6900 = 69%

⚙️ Configuration Parameters​

Default Settings (Safe for Launch):​

maxSwapPercent = 5          // Max 5% CREATOR → WETH per transaction
swapSlippageBps = 300       // 3% max swap slippage
depositSlippageBps = 500    // 5% deposit slippage tolerance
swapPoolFee = 3000          // 0.3% fee tier (standard)

Adjust After Launch (if needed):​

strategy.setParameters(
    5,      // maxSwapPercent (1-10% recommended for 99/1)
    300,    // swapSlippageBps (300-500 bps)
    500,    // depositSlippageBps (500-1000 bps)
    3000    // swapPoolFee (3000 or auto-discover)
);

🔒 Safety Features​

✅ Battle-Tested from USD1/WLFI:​

  1. Slippage Protection - All swaps have min output
  2. Try/Catch on Deposits - Graceful failure, returns tokens
  3. Range Checks - Skips deposit if Charm out of range
  4. Single Atomic Deposits - No batching complexity
  5. Max Swap Limits - Prevents excessive swaps
  6. Emergency Withdraw - Owner can recover funds
  7. Unused Token Returns - Nothing stuck in strategy

✅ CREATOR-Specific Additions:​

  1. IStrategy Interface - Full CreatorOVault compatibility
  2. Single-sided Deposits - Handles 100% CREATOR input
  3. Auto WETH→CREATOR - Withdrawals return only CREATOR
  4. Harvest Tracking - Monitors profit for vault

📈 Expected Behavior​

Initial Launch (99% CREATOR, 1% WETH):​

Deposit #1: 1,000,000 CREATOR
├─ Keep:  990,000 CREATOR (99%)
├─ Swap:   10,000 CREATOR → ~100 WETH (1%)
└─ Charm: 990,000 CREATOR + 100 WETH

Subsequent Deposits:​

Deposit #2: 500,000 CREATOR
├─ Need:  ~5 WETH to match ratio
├─ Swap:  ~500 CREATOR → 5 WETH
└─ Charm: +495,000 CREATOR + 5 WETH

Withdrawals:​

Withdraw: 10% of strategy
├─ From Charm: 148,500 CREATOR + 1.5 WETH
├─ Swap WETH: 1.5 WETH → ~1,500 CREATOR
└─ Return: 150,000 CREATOR to vault

🎯 Integration with StrategyDeploymentBatcher​

Update the batcher to deploy CreatorCharmStrategyV2 instead of the old one:

// In StrategyDeploymentBatcher.sol
result.creatorCharmStrategy = address(new CreatorCharmStrategyV2(
    creatorVault,
    underlyingToken,      // CREATOR
    quoteToken,           // WETH
    UNISWAP_ROUTER,       // Base SwapRouter
    result.charmVault,    // Charm vault (just deployed)
    result.v3Pool,        // CREATOR/WETH V3 pool (just created)
    msg.sender            // Owner
));

// Initialize approvals
CreatorCharmStrategyV2(result.creatorCharmStrategy).initializeApprovals();

✅ Verification Checklist​

Before launch, verify:

  • CreatorCharmStrategyV2 deployed
  • CharmAlphaVault deployed for CREATOR/WETH
  • CREATOR/WETH V3 pool created (0.3% fee tier)
  • Strategy has approvals initialized
  • Strategy.setCharmVault() called
  • Strategy.setSwapPool() called
  • Vault.addStrategy() called with correct allocation
  • Strategy.isActive() returns true
  • Strategy.asset() returns CREATOR address
  • Optional: zRouter configured
  • Optional: Auto fee tier enabled
