|
||||||
|
✅ Arbitrage detector initialized
|
||||||
|
✅ Bot scanning every 5 seconds
|
||||||
|
✅ All systems operational
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🚀 Quick Start (3 Steps)
|
||||||
|
|
||||||
|
### Step 1: Deploy Flash Loan Contract (~2 minutes)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
export PRIVATE_KEY="0xYOUR_PRIVATE_KEY"
|
||||||
|
export ARBISCAN_API_KEY="YOUR_ARBISCAN_KEY" # Optional but recommended
|
||||||
|
|
||||||
|
./scripts/deploy-contract.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
**What happens:**
|
||||||
|
- Compiles Solidity contract
|
||||||
|
- Deploys to Arbitrum mainnet (~$0.10 cost)
|
||||||
|
- Verifies on Arbiscan (optional)
|
||||||
|
- Generates Go bindings
|
||||||
|
- Saves contract address
|
||||||
|
|
||||||
|
**Output:**
|
||||||
|
```
|
||||||
|
✅ Contract deployed successfully!
|
||||||
|
📍 Contract Address: 0x... (saved to .contract-address)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 2: Run the Bot
|
||||||
|
|
||||||
|
```bash
|
||||||
|
export ARBITRUM_RPC_URL="https://arb1.arbitrum.io/rpc"
|
||||||
|
export PRIVATE_KEY="0xYOUR_PRIVATE_KEY"
|
||||||
|
|
||||||
|
./bin/mev-flashloan --min-profit 10
|
||||||
|
```
|
||||||
|
|
||||||
|
**What happens:**
|
||||||
|
- Connects to Arbitrum
|
||||||
|
- Discovers profitable pools
|
||||||
|
- Scans for arbitrage every 30 seconds (configurable)
|
||||||
|
- Simulates profitability
|
||||||
|
- Executes profitable trades via flash loans
|
||||||
|
|
||||||
|
**Example Output:**
|
||||||
|
```
|
||||||
|
✅ opportunities found! count=1
|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
**Shows:**
|
||||||
|
- Contract balance updates

## 💰 Economics
|
||||||
|
|
||||||
|
### Capital Requirements
|
||||||
|
|
||||||
|
| Item | Amount | Notes |
|
||||||
|
|------|--------|-------|
|
||||||
|
| **Bot Capital** | **$0** | Uses flash loans! |
|
||||||
|
| Deployment Gas | ~$0.10 | One-time cost |
|
||||||
|
| Execution Gas per trade | ~$0.05 | Arbitrum is cheap |
|
||||||
|
| Flash Loan Fee | 0.05% | Aave V3 standard |
|
||||||
|
|
||||||
|
### Profitability Example
|
||||||
|
|
||||||
|
**Scenario: 10 ETH Arbitrage**
|
||||||
|
|
||||||
|
```
|
||||||
|
Pool A: 1 ETH = 3000 USDC
|
||||||
|
Pool B: 1 ETH = 3030 USDC (1% difference)
|
||||||
|
|
||||||
|
Execution:
|
||||||
|
1. Flash loan 10 ETH from Aave
|
||||||
|
2. Swap 10 ETH → 30,000 USDC on Pool A
|
||||||
|
3. Swap 30,000 USDC → 10.1 ETH on Pool B
|
||||||
|
4. Repay 10.005 ETH (10 ETH + 0.05% fee)
|
||||||
|
5. Profit: 0.095 ETH = $285
|
||||||
|
|
||||||
|
Costs:
|
||||||
|
- Flash loan fee: 0.005 ETH = $15
|
||||||
|
- Gas cost: $0.05
|
||||||
|
- Total costs: $15.05
|
||||||
|
|
||||||
|
Net Profit: $285 - $15.05 = $269.95
|
||||||
|
```
|
||||||
|
|
||||||
|
**Daily Potential (10 trades):** $2,699
|
||||||
|
**Monthly Potential:** $80,985
|
||||||
|
**Capital Required:** $0

|
## 📊 Monitoring & Maintenance
|
||||||
|
|
||||||
|
### Real-time Monitoring
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Terminal 1: Run bot
|
||||||
|
./bin/mev-flashloan
|
||||||
|
|
||||||
|
# Terminal 2: Monitor profits
|
||||||
|
./scripts/monitor-profits.sh
|
||||||
|
|
||||||
|
# Terminal 3: Watch logs
|
||||||
|
tail -f logs/mev-bot.log
|
||||||
|
```
|
||||||
|
|
||||||
|
### Arbiscan Integration
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# View contract
|
||||||
|
https://arbiscan.io/address/YOUR_CONTRACT_ADDRESS
|
||||||
|
|
||||||
|
# View owner balance
|
||||||
|
https://arbiscan.io/address/YOUR_WALLET_ADDRESS
|
||||||
|
|
||||||
|
# View transactions
|
||||||
|
https://arbiscan.io/address/YOUR_CONTRACT_ADDRESS#internaltx
|
||||||
|
```
|
||||||
|
|
||||||
|
### Key Metrics to Track
|
||||||
|
|
||||||
|
- **Opportunities Found**: How many arb opportunities detected
|
||||||
|
- **Success Rate**: % of profitable executions
|
||||||
|
- **Average Profit**: Mean profit per trade
|
||||||
|
- **Gas Costs**: Total gas spent
|
||||||
|
- **Net ROI**: (Total Profit - Gas) / Time
|
||||||
|
|
||||||
|
## 🛡️ Safety Features
|
||||||
|
|
||||||
|
### Built-in Protections ✅
|
||||||
|
|
||||||
|
- [x] Minimum profit threshold (reject unprofitable trades)
|
||||||
|
- [x] Gas price limit (don't execute when gas is high)
|
||||||
|
- [x] Atomic flash loans (all-or-nothing execution)
|
||||||
|
- [x] Emergency withdraw (recover stuck tokens)
|
||||||
|
- [x] Owner-only functions (secure contract access)
|
||||||
|
- [x] Simulation before execution
|
||||||
|
- [x] Comprehensive error handling
|
||||||
|
|
||||||
|
### Risk Mitigation
|
||||||
|
|
||||||
|
| Risk | Mitigation |
|
||||||
|
|------|-----------|
|
||||||
|
| Front-running | Use Flashbots/private mempool (future) |
|
||||||
|
| Slippage | Set minimum output amounts (future) |
|
||||||
|
| Gas spikes | Max gas price configured |
|
||||||
|
| Failed swaps | Flash loan auto-reverts |
|
||||||
|
| Smart contract bugs | Start small, audit contract |
|
||||||
|
| Price manipulation | Only trade liquid pools (>$10k) |
|
||||||
|
|
||||||
|
## 🚨 Important Notes
|
||||||
|
|
||||||
|
### Before Production
|
||||||
|
|
||||||
|
1. **Test on Testnet First**
|
||||||
|
```bash
|
||||||
|
# Use Arbitrum Goerli testnet
|
||||||
|
export ARBITRUM_RPC_URL="https://goerli-rollup.arbitrum.io/rpc"
|
||||||
|
./bin/mev-flashloan --min-profit 1 # Lower threshold for testing
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Start Small**
|
||||||
|
- Begin with 0.1 ETH trades
|
||||||
|
- Monitor for 24 hours
|
||||||
|
- Gradually increase trade size
|
||||||
|
|
||||||
|
3. **Security Checklist**
|
||||||
|
- [ ] Private key stored securely (hardware wallet recommended)
|
||||||
|
- [ ] Contract verified on Arbiscan
|
||||||
|
- [ ] Emergency withdraw function tested
|
||||||
|
- [ ] Monitoring alerts configured
|
||||||
|
- [ ] Backup RPC endpoints configured
|
||||||
|
|
||||||
|
4. **Legal Compliance**
|
||||||
|
- Arbitrage is legal in most jurisdictions
|
||||||
|
- Check local regulations
|
||||||
|
- Consider tax implications
|
||||||
|
- Keep records of all trades
|
||||||
|
|
||||||
|
## 📈 Optimization Tips
|
||||||
|
|
||||||
|
### Performance Tuning
|
||||||
|
|
||||||
|
1. **Scan Interval**
|
||||||
|
```bash
|
||||||
|
# Faster scanning = more opportunities
|
||||||
|
--interval 10s # Every 10 seconds
|
||||||
|
--interval 5s # Every 5 seconds (aggressive)
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Profit Threshold**
|
||||||
|
```bash
|
||||||
|
# Lower threshold = more trades
|
||||||
|
--min-profit 5 # 0.05% minimum (more trades)
|
||||||
|
--min-profit 20 # 0.2% minimum (fewer but bigger trades)
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **RPC Endpoints**
|
||||||
|
```bash
|
||||||
|
# Use fastest RPC for lower latency
|
||||||
|
# Try multiple providers:
|
||||||
|
# - Alchemy
|
||||||
|
# - Infura
|
||||||
|
# - QuickNode
|
||||||
|
# - Your own node (fastest!)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Scaling Up
|
||||||
|
|
||||||
|
Once profitable:
|
||||||
|
|
||||||
|
1. **Add More DEXes**
|
||||||
|
- Implement Sushiswap parser
|
||||||
|
- Add Camelot support
|
||||||
|
- Support Curve pools
|
||||||
|
|
||||||
|
2. **3-Hop Arbitrage**
|
||||||
|
- A → B → C → A paths
|
||||||
|
- More opportunities
|
||||||
|
- Higher gas costs
|
||||||
|
|
||||||
|
3. **Cross-DEX Strategies**
|
||||||
|
- Multi-protocol arbitrage
|
||||||
|
- Liquidity aggregation
|
||||||
|
- Advanced routing
|
||||||
|
|
||||||
|
## 🐛 Troubleshooting
|
||||||
|
|
||||||
|
### Common Issues
|
||||||
|
|
||||||
|
**"Pool discovery complete poolsFound=0"**
|
||||||
|
```bash
|
||||||
|
# RPC might be rate limiting
|
||||||
|
# Solution: Use paid RPC endpoint or your own node
|
||||||
|
export ARBITRUM_RPC_URL="https://arb-mainnet.g.alchemy.com/v2/YOUR_KEY"
|
||||||
|
```
|
||||||
|
|
||||||
|
**"Gas price too high"**
|
||||||
|
```bash
|
||||||
|
# Increase max gas price
|
||||||
|
--max-gas-price 2000000000 # 2 gwei
|
||||||
|
```
|
||||||
|
|
||||||
|
**"No opportunities found"**
|
||||||
|
```bash
|
||||||
|
# Markets are efficient! Try:
|
||||||
|
# 1. Lower profit threshold
|
||||||
|
# 2. Faster scanning
|
||||||
|
# 3. Add more pools
|
||||||
|
# 4. Check during high volatility
|
||||||
|
```
|
||||||
|
|
||||||
|
**"Flash loan execution failed"**
|
||||||
|
```bash
|
||||||
|
# Check:
|
||||||
|
# 1. Contract has enough ETH for gas
|
||||||
|
# 2. Pools have sufficient liquidity
|
||||||
|
# 3. No front-running (use Flashbots)
|
||||||
|
```
