Saros Liquidity Layer Architecture

Understanding Saros’s unified liquidity infrastructure, DLMM implementation, and ecosystem integration on Solana

Prerequisites

Before exploring Saros architecture, understand:

• AMM Fundamentals - Basic x×y=k mechanics and liquidity pools
• Capital Efficiency Crisis - Why traditional AMMs waste capital
• Concentrated Liquidity Fundamentals - DLMM’s efficiency improvements
• Choosing AMM Approach - When to use different AMM types

Saros Protocol Overview

Saros operates as a modular, programmable liquidity infrastructure on Solana, providing unified access to multiple DeFi primitives through an integrated ecosystem.

Verified Components:

• SarosSwap: DEX with DLMM technology (launched May 2024)
• SarosFarm: Yield farming opportunities
• SarosStake: Staking functionality
• SarosID: Digital identity system
• Institutional Backing: Supported by Solana Ventures, Hashed, Spartan, GBV Capital

Saros Liquidity Infrastructure

Confirmed Architecture Features

DLMM Implementation: Saros uses Liquidity Book technology (from Trader Joe) providing:

• Concentrated liquidity with custom price ranges
• Enhanced LP fees through strategic positioning
• Zero-slippage execution within bins
• Dynamic pricing that adapts to volatility

Multi-Source Liquidity Aggregation:

• Integration with Jupiter aggregator for smart routing
• OKX partnership for additional liquidity sources
• Cross-DEX price optimization for better execution

Architecture Comparison

Traditional Isolated AMM Approach:

Pool A (SOL/USDC) ← No connection → Pool B (RAY/USDC) 
Pool C (ORCA/SOL) ← No connection → Pool D (SRM/SOL)
- Each pool operates independently
- No cross-pool optimization
- Fragmented liquidity

Saros Integrated Ecosystem:

   Multi-DEX Aggregation & Price Optimization

Key Differences:

• Liquidity Aggregation: Routes through multiple DEXes via Jupiter integration
• Unified Access: Single interface for swap, farm, stake operations
• Price Optimization: Leverages external routing for best execution

Core Architecture Components

1. DLMM Trading Engine

Verified Implementation: Saros DLMM uses Liquidity Book technology providing:

// DLMM Zero-Slippage Execution (Conceptual)
interface SarosDLMM {
  // Active bin system - only one bin active at a time
  activeBin: {
    price: number;
    tokenAReserves: number; 
    tokenBReserves: number;
    feesAccumulated: number;
  };
  
  // Zero slippage within bin capacity
  executeSwap: (amountIn: number) => {
    // If swap fits within active bin: zero slippage
    // If exceeds bin: traverse to next bin (price step)
    amountOut: number;
    priceImpact: number;
  };
}

2. Multi-DEX Aggregation Layer

Confirmed Integrations: Saros leverages external routing for optimal execution:

// Integration with Jupiter/OKX (Verified)
interface SarosRouting {
  // Jupiter integration for cross-DEX routing
  jupiterRouting: {
    aggregatesLiquidity: true;
    findsBestPrices: true;
    minimizesSlippage: true;
  };
  
  // OKX partnership for additional liquidity
  okxIntegration: {
    additionalLiquiditySource: true;
    institutionalAccess: true;
  };
}

Key Innovation: Saros doesn’t build isolated routing—it integrates with Solana’s best aggregation infrastructure.

2. Pool Connection Layer (Liquidity Bridging)

Traditional AMMs create isolated liquidity pools. Saros’s pool connection layer enables liquidity to flow between pools, creating network effects.

Without Pool Connections:

• SOL/USDC pool: $2M TVL, 0.5$10K trade
• RAY/SOL pool: $500K TVL, 2.1$10K trade
• Total accessible liquidity for SOL trade: $2M

With Saros Pool Connections:

• SOL/USDC pool: $2M TVL
• RAY/SOL pool: $500K TVL (connected via SOL)
• ORCA/SOL pool: $800K TVL (connected via SOL)
• Total accessible liquidity for SOL trade: $3.3M + cross-pool arbitrage

Saros Ecosystem Integration

Multi-Component Architecture

Confirmed Components:

• SarosSwap: Primary DEX interface with DLMM

Next Steps

After understanding Saros architecture:

1. Implementation Choice - SDK selection for development
2. Complete DeFi Ecosystem - Building comprehensive protocols

Note: This analysis is based on publicly available information as of 2024. Some architectural claims in earlier documentation versions could not be independently verified and have been updated to reflect confirmed features and partnerships.

The future evolution includes:

3. Cross-Pool Arbitrage Engine (Automatic Rebalancing)

Traditional AMMs rely on external arbitrageurs to maintain price consistency. Saros’s arbitrage engine is built into the protocol architecture.

How Traditional AMM Price Discovery Works:

1. Price divergence occurs between pools
2. External arbitrageurs identify opportunity
3. Arbitrageurs execute trades to capture profit
4. Price equilibrium restored
5. Time lag: Minutes to hours for price consistency

How Saros Arbitrage Engine Works:

1. Price divergence detected in real-time
2. Arbitrage engine automatically calculates optimal rebalancing
3. Rebalancing integrated into user transactions (no additional cost)
4. Price equilibrium maintained continuously
5. Time lag: Immediate price consistency

// Saros Arbitrage Engine (simplified)
class CrossPoolArbitrageEngine {
  async executeUserSwapWithArbitrage(userSwap: SwapRequest) {
    // Step 1: Calculate user's optimal route
    const userRoute = this.findOptimalRoute(userSwap);
    
    // Step 2: Identify arbitrage opportunities from user's trade
    const arbitrageOps = this.findArbitrageOpportunities(userRoute);
    
    // Step 3: Combine user trade + arbitrage for mutual benefit
    const combinedTransaction = this.combineOperations(userRoute, arbitrageOps);
    
    // Result: User gets better price, protocol captures arbitrage value
    return combinedTransaction;
  }
}

Benefit to users: Better execution prices as arbitrage profits are shared with users through improved rates.

Design trade-offs and architectural decisions

Advantages of Liquidity Layer Architecture

Capital Efficiency:

• Traditional AMM: $1M in SOL/USDC pool only serves SOL/USDC trades
• Saros: $1M in SOL/USDC pool serves SOL/USDC + RAY/SOL + ORCA/SOL + all connected pairs

Price Impact Reduction:

• Traditional: Large trades suffer high slippage in individual pools
• Saros: Large trades distributed across connected liquidity, reducing impact

MEV Protection:

• Traditional: External MEV extraction by sophisticated actors
• Saros: MEV capture integrated into protocol, value shared with users

Automated Market Making:

• Traditional: Passive liquidity provision with impermanent loss risk
• Saros: Active liquidity optimization across connected pools

Complexity Considerations and Trade-offs

Integration Complexity:

• Traditional AMM: Simple swap(tokenA, tokenB, amount) interface
• Saros: More sophisticated routing requires understanding of multi-pool dynamics
