🔍 CREATOR/WETH vs CREATOR/USDC Analysis

The Core Problem Doesn't Change

Current Issue:

User deposits CREATOR → Vault → Strategy → Charm Vault

Problem: Charm needs BOTH tokens for LP
- CREATOR ✅ (we have this)
- USDC ❌ (we don't have this)

With WETH Instead:

User deposits CREATOR → Vault → Strategy → Charm Vault

Problem: Charm STILL needs BOTH tokens
- CREATOR ✅ (we have this)  
- WETH ❌ (we still don't have this!)

The pair doesn't matter - we need BOTH tokens regardless! ⚠️

💡 But WETH Might Be Slightly Better:

WETH Advantages:

1. ✅ More liquid - Higher trading volume
2. ✅ Native to ETH - No stablecoin risk
3. ✅ Higher LP fees - ETH pairs trade more
4. ✅ Better for DeFi - Most protocols use WETH
5. ✅ Easier to get - Just wrap ETH

USDC Advantages:

1. ✅ Stable value - No price volatility
2. ✅ Lower IL risk - CREATOR/USDC has less impermanent loss
3. ✅ Dollar-denominated - Easier for users to understand

🎯 The REAL Question: How to Get the Second Token?

We have 3 options regardless of WETH or USDC:

Option A: Swap Half (Most Viable)

function deposit(uint256 creatorAmount) external returns (uint256) {
    // 1. Take CREATOR tokens
    IERC20(CREATOR).transferFrom(vault, address(this), creatorAmount);
    
    // 2. Swap 50% CREATOR → WETH (or USDC)
    uint256 halfCreator = creatorAmount / 2;
    uint256 wethReceived = _swapOnUniswap(halfCreator);
    
    // 3. Deposit BOTH to Charm
    charmVault.deposit(
        halfCreator,   // CREATOR
        wethReceived,  // WETH
        0, 0, address(this)
    );
}

With WETH: ✅ Better - higher liquidity, easier swaps
With USDC: ⚠️ Okay - but less liquid for swaps

Option B: Treasury Provides Match

// Treasury pre-deposits WETH to strategy
// Strategy uses it to match CREATOR deposits
function deposit(uint256 creatorAmount) external returns (uint256) {
    uint256 wethBalance = IERC20(WETH).balanceOf(address(this));
    uint256 wethNeeded = _calculateWethNeeded(creatorAmount);
    
    require(wethBalance >= wethNeeded, "Need more WETH");
    
    charmVault.deposit(creatorAmount, wethNeeded, 0, 0, address(this));
}

With WETH: ✅ Treasury can easily get WETH
With USDC: ✅ Treasury can easily get USDC
(Both work equally here)

Option C: Use Flash Liquidity

// Borrow WETH via flash loan to create LP, then repay
function deposit(uint256 creatorAmount) external returns (uint256) {
    // 1. Flash loan WETH
    // 2. Create CREATOR/WETH LP
    // 3. LP fees pay back flash loan
    // 4. Keep excess
}

With WETH: ✅ Many WETH flash loan providers
With USDC: ✅ Many USDC flash loan providers too
(Both work)

🏆 Winner: CREATOR/WETH

Recommendation: Use CREATOR/WETH

Why:

1. ✅ Higher volume = more LP fees earned
2. ✅ Better liquidity = easier swaps
3. ✅ More integrations = more strategies later
4. ✅ Native token = no stablecoin risk

The swap solution becomes:

// Swap 50% CREATOR → WETH on Uniswap V3
// Then deposit both to Charm

This is easier with WETH because:

• CREATOR/WETH pool likely has more liquidity than CREATOR/USDC
• Less hops (direct swap vs might need CREATOR→WETH→USDC)
• Lower slippage

💡 Practical Implementation:

With CREATOR/WETH:

contract CreatorCharmStrategy is IStrategy {
    ISwapRouter public constant uniswapRouter = 0x...;
    
    function deposit(uint256 amount) external override returns (uint256) {
        // 1. Receive CREATOR
        IERC20(CREATOR).transferFrom(vault, address(this), amount);
        
        // 2. Swap 50% to WETH
        uint256 halfAmount = amount / 2;
        uint256 wethReceived = _swapCreatorForWeth(halfAmount);
        
        // 3. Deposit both to Charm
        (uint256 shares,,) = charmVault.deposit(
            halfAmount,      // CREATOR remaining
            wethReceived,    // WETH from swap
            0, 0,
            address(this)
        );
        
        return halfAmount + wethReceived; // Total value deposited
    }
    
    function _swapCreatorForWeth(uint256 amountIn) internal returns (uint256) {
        ISwapRouter.ExactInputSingleParams memory params = ISwapRouter.ExactInputSingleParams({
            tokenIn: CREATOR,
            tokenOut: WETH,
            fee: 3000, // 0.3%
            recipient: address(this),
            deadline: block.timestamp,
            amountIn: amountIn,
            amountOutMinimum: 0, // Should calculate slippage
            sqrtPriceLimitX96: 0
        });
        
        return uniswapRouter.exactInputSingle(params);
    }
}

🎯 Final Answer:

YES - CREATOR/WETH is better than CREATOR/USDC!

But you still need to add swap logic because:

1. Vault receives only CREATOR
2. Charm needs CREATOR + WETH
3. Strategy must swap 50% CREATOR → WETH

WETH is easier to swap to and has better liquidity, so it's the right choice.
