Code Comparison: Same Operation, Different SDKs​

Simple Token Swap Implementation​

TypeScript SDK​

import { swapSaros, getSwapAmountSaros } from '@saros-finance/sdk';

async function executeSwap(fromToken: string, toToken: string, amount: number) {
  // Multi-step process with comprehensive error handling
  const quote = await getSwapAmountSaros(
    connection,
    fromToken,
    toToken,
    amount,
    0.5, // slippage
    poolParams
  );

  if (quote.priceImpact > 2.0) {
    throw new Error('Price impact too high');
  }

  const result = await swapSaros(
    connection,
    fromTokenAccount,
    toTokenAccount,
    amount,
    parseFloat(quote.amountOutWithSlippage),
    null,
    poolAddress,
    SWAP_PROGRAM_ID,
    walletAddress,
    fromToken,
    toToken
  );

  return result;
}

// ✅ Pros: Comprehensive, easy to understand
// ⚠️ Cons: More verbose, requires multiple steps

DLMM TypeScript SDK​

import { DLMMSDKv2 } from '@saros-finance/dlmm-sdk';

async function executeSwap(poolAddress: string, amount: number, isXToY: boolean) {
  const dlmm = new DLMMSDKv2(connection);
  
  // Streamlined DLMM-optimized swap
  const quote = await dlmm.getSwapQuote({
    poolAddress,
    amount,
    isXToY,
    slippageTolerance: 0.1 // Lower slippage for concentrated liquidity
  });

  const swapTx = await dlmm.swapWithQuote({
    quote,
    wallet: userWallet,
    computeUnitPrice: 1000 // Priority fee for faster execution
  });

  return await dlmm.sendAndConfirm(swapTx);
}

// ✅ Pros: Optimized for DLMM, cleaner API
// ⚠️ Cons: DLMM pools only, no AMM support

Rust DLMM SDK​

use saros_dlmm_sdk::prelude::*;

async fn execute_swap(
    client: &DlmmClient,
    pool_address: &str,
    amount: u64,
    is_x_to_y: bool
) -> Result<String, DlmmError> {
    // High-performance swap with minimal allocations
    let swap = client
        .build_swap(pool_address)?
        .amount(amount)
        .direction(is_x_to_y)
        .slippage_bps(10) // 0.1% slippage
        .build();

    // Execute with optimized transaction
    let result = client.execute_swap(swap).await?;
    
    Ok(result.signature)
}

// ✅ Pros: Maximum performance, minimal resource usage
// ⚠️ Cons: Requires Rust knowledge, compilation setup

import { useSarosSDK, usePool, useSwap } from '@saros-finance/sdk/react';

function SwapInterface() {
  const { connection, wallet } = useSarosSDK();
  const pool = usePool('SOL-USDC');
  const { swap, loading, error } = useSwap();

  const handleSwap = async () => {
    try {
      const result = await swap({
        fromToken: 'SOL',
        toToken: 'USDC', 
        amount: 1.0,
        slippage: 0.5
      });
      
      console.log('Swap successful:', result.signature);
    } catch (err) {
      console.error('Swap failed:', err);
    }
  };

  return (
    <div className="swap-interface">
      <PoolInfo pool={pool} />
      <SwapForm onSwap={handleSwap} loading={loading} />
      {error && <ErrorDisplay error={error} />}
    </div>
  );
}

      staking: stakingPositions,
      farming: farmingPositions,
      liquidity: liquidityPositions
    });

    return {
      positions: { stakingPositions, farmingPositions, liquidityPositions },
      metrics: {
        totalValue: this.calculateTotalValue(stakingPositions, farmingPositions, liquidityPositions),
        dailyYield: totalYield.daily,

Migration Strategies​

From General to Specialized​

Phase 1: Start with TypeScript SDK​

// Begin with full-featured SDK
import { SarosSDK } from '@saros-finance/sdk';

const sdk = new SarosSDK(connection);
await sdk.executeSwap({ /* params */ });
await sdk.stakeTokens({ /* params */ });

Phase 2: Identify Performance Bottlenecks​

// Profile your application
console.time('Portfolio Load');
const portfolio = await sdk.getCompletePortfolio(wallet);
console.timeEnd('Portfolio Load'); // ~2000ms

// Identify heavy operations
const heavyOperations = [
  'DLMM position analysis',
  'Real-time price feeds',
  'Bulk transaction processing'
];

Phase 3: Migrate Heavy Operations​

// Hybrid approach: use specialized SDK for performance-critical parts
import { DLMMSDKv2 } from '@saros-finance/dlmm-sdk';

class HybridPortfolio {
  private generalSDK: SarosSDK;
  private dlmmSDK: DLMMSDKv2;

  async getPortfolio(wallet: string) {
    // Use general SDK for AMM and staking
    const [stakingPositions, farmingPositions] = await Promise.all([
