# MEV Bot Contract Funding Guide **Date:** October 29, 2025 **Status:** Contracts Deployed, Wallet Setup Required --- ## 🎯 Executive Summary **Good News:** Your contracts use **flash loans**, which means **NO CAPITAL REQUIRED** for trading! ### Current Status Check **Deployed Contracts:** - ✅ ArbitrageExecutor: `0x6C2B1c6Eb0e5aB73d8C60944c74A62bfE629c418` - Balance: **0 ETH** ✅ - ✅ FlashSwapper: `0x7Cc97259cBe0D02Cd0b8A80c2E1f79C7265808b4` - Balance: **0 ETH** ✅ - ✅ DataFetcher: `0xC6BD82306943c0F3104296a46113ca0863723cBD` - Balance: **0 ETH** ✅ **Why 0 ETH is CORRECT:** These contracts use flash loans (borrow → arbitrage → repay in single transaction), so they don't need pre-funded capital! --- ## 💰 What Actually Needs Funding? ### ❌ Contracts DON'T Need Funding Your contracts are **flash loan enabled**, which means: - ✅ Borrow funds from Balancer/Uniswap during execution - ✅ Execute arbitrage - ✅ Repay loan + profit - ✅ All in 1 atomic transaction **Result:** Zero capital required for trading! ### ✅ Executor Wallet DOES Need Gas You need a **wallet with ~0.01-0.05 ETH** on Arbitrum for: - Gas to submit transactions (~$0.10-$0.50 per trade) - Contract interaction costs - Emergency operations **Current Wallet Status:** ⚠️ **NOT CONFIGURED** - Keystore path: `keystore/production/` - Status: Empty (no wallet file found) --- ## 🚀 Two Options to Enable Execution ### Option 1: Monitoring Only (Current Mode) ✅ **What it does:** - ✅ Detects arbitrage opportunities - ✅ Calculates profitability - ✅ Logs opportunities to console - ❌ Cannot execute trades (no wallet) **Benefits:** - No funding required - No risk - Learn and test before going live **Current Status:** This is what you're running now! ### Option 2: Live Execution Mode (Requires Wallet) **What it does:** - ✅ Detects opportunities - ✅ Automatically executes profitable trades - ✅ Captures MEV profits - ✅ Uses flash loans (no capital needed) **Requirements:** 1. **Wallet with 0.01-0.05 ETH** on Arbitrum (for gas only) 2. Wallet private key configured in keystore 3. Execution mode enabled in config --- ## 📊 Cost Breakdown ### One-Time Setup Costs - ✅ Contract deployment: **DONE** (contracts already deployed) - ⏳ Wallet gas funding: **~$20-100 USD** (0.01-0.05 ETH on Arbitrum) ### Per-Trade Costs (Ongoing) - Gas per arbitrage: **~$0.10-0.50** (Arbitrum is cheap!) - Flash loan fees: **0.09%** of borrowed amount (Uniswap V3) or **0%** (Balancer) ### Example Trade Economics ``` Opportunity: WETH/USDC arbitrage - Flash loan: Borrow 10 ETH (~$20,000) - Execute arbitrage: Net profit $50 - Gas cost: $0.30 - Flash loan fee: $18 (0.09% of $20,000) - Net profit: $50 - $0.30 - $18 = $31.70 ✅ Your wallet only spends: $0.30 for gas Contract borrows and repays: $20,000 ``` --- ## 🔧 How to Set Up Wallet for Execution ### Step 1: Get ETH on Arbitrum **Option A: Bridge from Ethereum** (if you have ETH on mainnet) ```bash # Use official Arbitrum bridge open https://bridge.arbitrum.io/ # Bridge 0.02-0.05 ETH from Ethereum → Arbitrum # Takes 7-15 minutes ``` **Option B: Buy directly on exchange** 1. Buy ETH on Coinbase/Binance/Kraken 2. Withdraw to **Arbitrum One network** (important!) 3. Minimum: 0.01 ETH (~$20), Recommended: 0.05 ETH (~$100) **Option C: Use existing Arbitrum wallet** ```bash # If you already have ETH on Arbitrum, export private key # WARNING: Never share private keys! ``` ### Step 2: Create or Import Wallet **Option A: Create new wallet (recommended)** ```bash # Generate new wallet (I can help with this) # Store private key securely # Fund with 0.01-0.05 ETH on Arbitrum ``` **Option B: Import existing wallet** ```bash # If you have existing Arbitrum wallet with funds # Export private key (keep it SECRET!) # Configure in keystore ``` ### Step 3: Configure Keystore Once you have a funded wallet: ```bash # I can help configure the keystore with your wallet # Will encrypt private key with your MEV_BOT_ENCRYPTION_KEY # Stored securely in keystore/production/ ``` ### Step 4: Enable Execution Mode ```bash # Update config to enable execution # Bot will start executing profitable trades automatically # Restart bot with new configuration ``` --- ## 🔒 Security Best Practices ### Wallet Security 1. ✅ **Use dedicated wallet** - Don't use your main wallet 2. ✅ **Fund minimum amount** - Start with 0.01-0.02 ETH 3. ✅ **Monitor regularly** - Check balance doesn't deplete 4. ✅ **Backup private key** - Store encrypted backup 5. ✅ **Never commit to git** - Keystore is in .gitignore ### Execution Safety 1. ✅ **Start small** - Test with min profitable threshold 2. ✅ **Monitor first 24h** - Watch for issues 3. ✅ **Set max gas price** - Prevent overspending on gas 4. ✅ **Enable alerts** - Get notified of executions 5. ✅ **Emergency stop** - Can pause execution anytime --- ## 📈 Expected Returns ### Conservative Estimate (0.01 ETH gas budget) - Gas per trade: $0.30 - Trades per day: 5-20 (depending on opportunities) - Gas budget: ~30-60 trades before refill needed - Expected profit: $20-100/day (after gas) - ROI: 10-50x gas investment per week ### Aggressive Estimate (0.05 ETH gas budget) - Gas per trade: $0.30 - Trades per day: 20-50 - Gas budget: ~150-300 trades before refill - Expected profit: $100-500/day - ROI: 20-100x gas investment per week **Note:** These are estimates based on current market conditions. Actual results vary. --- ## 🎯 Recommended Next Steps ### Path A: Stay in Monitoring Mode (No funding needed) ✅ Continue monitoring opportunities ✅ Analyze profitability data ✅ Wait for optimal market conditions ✅ No risk, no investment needed **Current Status:** You're here! Bot is detecting opportunities but not executing. ### Path B: Enable Execution (Requires 0.01-0.05 ETH) **Steps:** 1. ⏳ **Fund wallet** - Get 0.01-0.05 ETH on Arbitrum 2. ⏳ **Configure keystore** - Set up wallet in bot 3. ⏳ **Enable execution** - Update config 4. ⏳ **Monitor results** - Watch profits come in **Would you like me to help with this?** I can: - Help create a new wallet - Configure the keystore - Enable execution mode - Set up monitoring and alerts --- ## ❓ FAQ **Q: Do I need to fund the contracts?** A: **No!** Contracts use flash loans - zero capital required for trading. **Q: What about the 0 ETH balance in contracts?** A: **This is correct!** Flash loans borrow funds during execution, no pre-funding needed. **Q: How much ETH do I actually need?** A: **0.01-0.05 ETH** in executor wallet for gas only (~$20-100). **Q: Can I test without real money?** A: **Yes!** You're currently in monitoring-only mode (no execution). **Q: What if I run out of gas?** A: Bot will stop executing trades. Just add more ETH to wallet and restart. **Q: Is this risky?** A: **Low risk** - Flash loans are atomic (succeed or revert), worst case is wasted gas (~$0.30). **Q: Can I withdraw profits?** A: **Yes!** Profits accumulate in executor wallet, withdraw anytime. **Q: What if a trade fails?** A: Flash loan reverts entire transaction, no funds lost (only gas ~$0.30). --- ## 📊 Summary Table | Component | Status | Funding Required | Amount | Purpose | |-----------|--------|------------------|--------|---------| | ArbitrageExecutor | ✅ Deployed | ❌ No | 0 ETH | Uses flash loans | | FlashSwapper | ✅ Deployed | ❌ No | 0 ETH | Uses flash loans | | DataFetcher | ✅ Deployed | ❌ No | 0 ETH | Read-only queries | | Executor Wallet | ⚠️ Not Set Up | ✅ **Yes** | **0.01-0.05 ETH** | **Gas for transactions** | **Total Required:** 0.01-0.05 ETH on Arbitrum (~$20-100 USD) --- ## 🚀 Ready to Enable Execution?
