Launch Flow Architecture

Understanding the launch flow architecture is essential for developers integrating with POTLAUNCH and users wanting to understand how token launches work under the hood.

Architecture Overview

The POTLAUNCH launch flow consists of multiple interconnected stages, each handling specific aspects of the token launch lifecycle.

System Components

1. Launch Initialization Layer

Responsibilities:

Token metadata validation
Smart contract deployment
Initial configuration setup
Security checks

Technical Flow:


interface LaunchInitialization {
  // Token Metadata
  metadata: {
    name: string;
    symbol: string;
    description: string;
    image: string;
    socials: SocialLinks;
  };
  
  // Token Configuration
  config: {
    supply: number;
    decimals: number;
    mintAuthority: null; // Revoked for security
    freezeAuthority: null; // Revoked for fairness
  };
  
  // Launch Parameters
  launchConfig: {
    curveType: 'linear' | 'exponential' | 'logarithmic';
    initialPrice: number;
    targetMarketCap: number;
    graduationThreshold: number;
  };
}

Process:

Metadata Validation

Verify all required fields are present
Check image format and size
Validate social links
Ensure uniqueness of token symbol

Smart Contract Deployment

Deploy SPL token contract
Initialize token mint
Set up token account
Revoke mint and freeze authorities

Bonding Curve Setup

Create curve contract instance
Initialize reserve accounts
Set pricing parameters
Configure fee structure

Security Initialization

Enable anti-rug mechanisms
Set up liquidity locks
Configure graduated migration
Activate monitoring systems

2. Configuration Layer

Bonding Curve Configuration:


interface BondingCurveConfig {
  // Curve Parameters
  curveType: CurveType;
  parameters: {
    a: number; // Linear coefficient
    b: number; // Exponential coefficient
    c: number; // Constant offset
  };
  
  // Reserve Configuration
  reserveRatio: number; // 0-1
  initialReserve: number; // SOL
  
  // Price Bounds
  minPrice: number;
  maxPrice: number;
  
  // Graduation Settings
  graduationThreshold: {
    marketCap: number;
    totalRaised: number;
    timelock: number; // seconds
  };
}

Curve Types:

Linear Curve
```
Price(supply) = a × supply + b
```
- Constant price increase
- Predictable pricing
- Suitable for stable launches
Exponential Curve
```
Price(supply) = a × e^(b × supply) + c
```
- Accelerating price growth
- Early bird advantages
- Rewards early participants
Logarithmic Curve
```
Price(supply) = a × ln(supply) + b
```
- Decelerating price growth
- More accessible at scale
- Long-term sustainable

Fee Configuration:


interface FeeStructure {
  // Trading Fees
  buyFee: number; // Basis points (100 = 1%)
  sellFee: number; // Basis points
  
  // Platform Fees
  platformFee: number; // Platform revenue
  creatorFee: number; // Creator royalty
  
  // Distribution
  feeRecipients: {
    address: PublicKey;
    percentage: number;
  }[];
}

3. Trading Engine Layer

Order Processing:


class TradingEngine {
  async executeBuy(params: BuyParams): Promise<Transaction> {
    // 1. Calculate current price
    const price = this.calculatePrice(params.amount);
    
    // 2. Calculate fees
    const fees = this.calculateFees(price, 'buy');
    
    // 3. Validate balance
    await this.validateBalance(params.buyer, price + fees);
    
    // 4. Execute trade
    const tx = await this.createBuyTransaction({
      buyer: params.buyer,
      amount: params.amount,
      price: price,
      fees: fees,
    });
    
    // 5. Update state
    await this.updateCurveState(params.amount, 'buy');
    
    return tx;
  }
  
  async executeSell(params: SellParams): Promise<Transaction> {
    // Similar flow for selling
  }
}

Price Calculation Engine:


class PriceCalculator {
  calculatePrice(
    currentSupply: number,
    tradeAmount: number,
    curveParams: CurveParameters
  ): number {
    // Integral calculation for bonding curve
    const integral = this.integrateCurve(
      currentSupply,
      currentSupply + tradeAmount,
      curveParams
    );
    
    return integral / tradeAmount; // Average price
  }
  
  calculateSlippage(
    amount: number,
    currentPrice: number
  ): number {
    // Slippage calculation based on curve derivative
    return this.derivativeCurve(amount) * amount / currentPrice;
  }
}

State Management:


interface CurveState {
  // Supply Tracking
  totalSupply: number;
  circulatingSupply: number;
  reserveSupply: number;
  
  // Reserve Tracking
  reserveBalance: number; // SOL
  targetReserve: number;
  
  // Trading Metrics
  totalVolume: number;
  totalBuys: number;
  totalSells: number;
  uniqueTraders: number;
  
  // Price Metrics
  currentPrice: number;
  highPrice: number;
  lowPrice: number;
  averagePrice: number;
  
  // Graduation Status
  marketCap: number;
  progressToGraduation: number; // 0-100%
  graduationEligible: boolean;
}

4. Graduation & Migration Layer

Graduation Criteria:


interface GraduationCriteria {
  // Market Cap Requirements
  minimumMarketCap: number; // e.g., 100,000 SOL
  
  // Volume Requirements
  minimumVolume: number; // e.g., 10,000 SOL
  minimumTrades: number; // e.g., 100 trades
  
  // Time Requirements
  minimumAge: number; // e.g., 24 hours
  
  // Community Requirements
  minimumHolders: number; // e.g., 50 holders
  minimumLiquidity: number; // e.g., 10 SOL
}

Migration Process:

Graduation Eligibility Check


async checkGraduationEligibility(): Promise<boolean> {
  const state = await this.getCurveState();
  const criteria = this.graduationCriteria;
  
  return (
    state.marketCap >= criteria.minimumMarketCap &&
    state.totalVolume >= criteria.minimumVolume &&
    state.totalBuys >= criteria.minimumTrades &&
    state.age >= criteria.minimumAge &&
    state.holders >= criteria.minimumHolders
  );
}

Liquidity Extraction


async extractLiquidity(): Promise<LiquidityPool> {
  // 1. Calculate total reserve
  const reserve = await this.getReserveBalance();
  
  // 2. Calculate token allocation
  const tokenAmount = this.calculateTokensForDEX(reserve);
  
  // 3. Prepare liquidity
  return {
    solAmount: reserve * 0.9, // 90% to DEX
    tokenAmount: tokenAmount,
    platformFee: reserve * 0.1, // 10% platform fee
  };
}

DEX Pool Creation


async createDEXPool(
  liquidity: LiquidityPool
): Promise<PoolAddress> {
  // 1. Choose DEX (Raydium or Meteora)
  const dex = this.selectDEX(liquidity);
  
  // 2. Create liquidity pool
  const pool = await dex.createPool({
    tokenA: this.tokenMint,
    tokenB: NATIVE_SOL,
    amountA: liquidity.tokenAmount,
    amountB: liquidity.solAmount,
  });
  
  // 3. Burn LP tokens (lock liquidity)
  await this.burnLPTokens(pool.lpMint);
  
  return pool.address;
}

Post-Migration


async finalizeMigration(): Promise<void> {
  // 1. Disable bonding curve
  await this.disableCurve();
  
  // 2. Update token metadata
  await this.updateMetadata({
    dexPool: this.dexPoolAddress,
    graduated: true,
    graduationDate: Date.now(),
  });
  
  // 3. Emit graduation event
  await this.emitGraduationEvent();
  
  // 4. Notify stakeholders
  await this.notifyGraduation();
}

5. Monitoring & Analytics Layer

Real-time Monitoring:


interface MonitoringSystem {
  // Price Monitoring
  trackPriceChanges(): void;
  detectPriceAnomalies(): void;
  alertOnVolatility(): void;
  
  // Trading Monitoring
  trackTradingVolume(): void;
  detectSuspiciousActivity(): void;
  monitorLargeTransactions(): void;
  
  // Health Monitoring
  checkSystemHealth(): void;
  validateStateConsistency(): void;
  monitorReserveBalance(): void;
}

Analytics Dashboard:


interface AnalyticsDashboard {
  // Trading Metrics
  volume24h: number;
  trades24h: number;
  uniqueTraders24h: number;
  
  // Price Metrics
  currentPrice: number;
  priceChange24h: number;
  priceHigh24h: number;
  priceLow24h: number;
  
  // Supply Metrics
  totalSupply: number;
  circulatingSupply: number;
  holderCount: number;
  topHolders: Holder[];
  
  // Graduation Progress
  progressToGraduation: number;
  estimatedGraduationTime: number;
}

Error Handling & Recovery

Error Types


enum LaunchError {
  // Initialization Errors
  INVALID_METADATA = 'INVALID_METADATA',
  INSUFFICIENT_FUNDS = 'INSUFFICIENT_FUNDS',
  
  // Trading Errors
  SLIPPAGE_EXCEEDED = 'SLIPPAGE_EXCEEDED',
  INSUFFICIENT_LIQUIDITY = 'INSUFFICIENT_LIQUIDITY',
  
  // System Errors
  NETWORK_ERROR = 'NETWORK_ERROR',
  CONTRACT_ERROR = 'CONTRACT_ERROR',
}

Recovery Mechanisms


class ErrorRecovery {
  async handleError(error: LaunchError): Promise<void> {
    switch (error) {
      case LaunchError.SLIPPAGE_EXCEEDED:
        // Retry with updated price
        await this.retryWithNewPrice();
        break;
        
      case LaunchError.NETWORK_ERROR:
        // Wait and retry
        await this.waitAndRetry();
        break;
        
      case LaunchError.CONTRACT_ERROR:
        // Emergency pause
        await this.emergencyPause();
        break;
    }
  }
}

Performance Optimization

Caching Strategy


class CacheManager {
  // Price Cache
  priceCache: LRU<string, number>;
  
  // State Cache
  stateCache: LRU<string, CurveState>;
  
  // TTL Configuration
  cacheTTL = {
    price: 1000, // 1 second
    state: 5000, // 5 seconds
    metadata: 60000, // 1 minute
  };
}

Batch Processing


class BatchProcessor {
  async processBatch(transactions: Transaction[]): Promise<void> {
    // Group transactions by type
    const groups = this.groupTransactions(transactions);
    
    // Process in parallel
    await Promise.all([
      this.processBuys(groups.buys),
      this.processSells(groups.sells),
    ]);
  }
}
