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:
- Wallet with 0.01-0.05 ETH on Arbitrum (for gas only)
- Wallet private key configured in keystore
- 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)
# 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
- Buy ETH on Coinbase/Binance/Kraken
- Withdraw to Arbitrum One network (important!)
- Minimum: 0.01 ETH (
$20), Recommended: 0.05 ETH ($100)
Option C: Use existing Arbitrum wallet
# 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)
# 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
# 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:
# 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
# Update config to enable execution
# Bot will start executing profitable trades automatically
# Restart bot with new configuration
🔒 Security Best Practices
Wallet Security
- ✅ Use dedicated wallet - Don't use your main wallet
- ✅ Fund minimum amount - Start with 0.01-0.02 ETH
- ✅ Monitor regularly - Check balance doesn't deplete
- ✅ Backup private key - Store encrypted backup
- ✅ Never commit to git - Keystore is in .gitignore
Execution Safety
- ✅ Start small - Test with min profitable threshold
- ✅ Monitor first 24h - Watch for issues
- ✅ Set max gas price - Prevent overspending on gas
- ✅ Enable alerts - Get notified of executions
- ✅ Emergency stop - Can pause execution anytime
📈 Expected Returns

- 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.

❓ 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: 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).
