        <div>
          <h4>🏛️ Traditional AMM (Main SDK)</h4>
          <ul>
            <li>✅ Uniform liquidity distribution (x*y=k)</li>
            <li>✅ Simple and predictable behavior</li>
            <li>✅ Lower complexity for LPs</li>
            <li>✅ Complete DeFi ecosystem (farming, staking, governance)</li>
            <li>✅ Battle-tested mathematical model</li>
            <li>❌ Capital inefficiency (most liquidity unused)</li>
            <li>❌ Higher slippage for large trades</li>
          </ul>
          
          <p><strong>Best for:</strong> Complete DeFi protocols, stable trading pairs, 
          set-and-forget liquidity providers</p>
        </div>
        
        <div>
          <h4>⚡ DLMM (Concentrated Liquidity)</h4>
          <ul>
            <li>✅ Concentrated liquidity (10-100x efficiency)</li>
            <li>✅ Better prices for traders</li>
            <li>✅ Higher fees for active LPs</li>
            <li>✅ Customizable price ranges</li>
            <li>❌ Higher complexity for LPs</li>
            <li>❌ Requires active management</li>
            <li>❌ Impermanent loss amplification</li>
          </ul>
          
          <p><strong>Best for:</strong> Professional trading, active liquidity management,

        <h4>🤔 Which Should You Choose?</h4>
        <p><strong>Choose Main SDK if:</strong> Building complete DeFi ecosystem, need farming/staking, 
        serving passive liquidity providers</p>
        <p><strong>Choose DLMM SDK if:</strong> Focused on trading efficiency, serving active traders,

🚀 Test Your DeFi Protocol

# Install dependencies
npm install

# Start development server
npm run dev

# Test the application
# 1. Connect wallet (Phantom/Solflare)
# 2. Try AMM trading (requires devnet tokens)
# 3. Test yield farming staking
# 4. Participate in governance voting

🎯 Success Validation

✅ Complete DeFi protocol when:

AMM trading interface works with wallet connection
Yield farming allows LP token staking and reward claims
Governance enables SAROS staking and proposal voting
All components integrate smoothly in single application
Users can navigate between all DeFi features seamlessly

🎉 Congratulations! You’ve built a comprehensive DeFi ecosystem that rivals established protocols.

💡 Main SDK Advantages

Complete Ecosystem: Unlike focused solutions, Main SDK provides everything needed for full DeFi protocols - trading, farming, staking, and governance in one package.

Battle-Tested AMM: Traditional x*y=k curve is well understood by users and provides predictable behavior for all liquidity providers.

Developer-Friendly: Simpler mathematics and uniform liquidity distribution make integration easier compared to concentrated liquidity solutions.

🚀 Next Steps

Advanced DeFi Features

Cross-chain integration, advanced routing, and institutional features

Liquidity Provision

Complete guide to providing and managing AMM liquidity

DeFi Protocol Development

Build your own DeFi protocols on top of Saros infrastructure

Production Deployment

Security, monitoring, and scaling for production DeFi applications

💡 Real DeFi Builder Insights

“The Main SDK let us build our yield farming aggregator in 2 weeks instead of 6 months. Having AMM, farming, and governance in one SDK was game-changing.” - DeFi Protocol Founder

“Our users love the predictable behavior of traditional AMM. No surprises, no impermanent loss amplification - just reliable DeFi.” - Product Manager

“The governance features let us build a truly decentralized protocol. Our community actively participates in every major decision.” - DAO Contributor

Production Considerations: This quick start demonstrates the patterns. For production, implement comprehensive security audits, monitoring, and risk management systems.

Choose Your Path: Main SDK excels for complete DeFi ecosystems with traditional AMM behavior. For advanced trading features, consider DLMM SDK for concentrated liquidity.
