Integration Pattern

import { PaywallBuilder, PricingStrategy } from '@nirholas/x402-ecosystem/premium';
import { SolidityCompiler } from '@nirholas/solidity-compiler';

// Compilation pricing
const compilerPricing = PricingStrategy.resourceBased({
  'compile-basic': 0,           // Free: basic compilation
  'compile-optimized': 0.01,    // $0.01: optimizer enabled
  'compile-max-opt': 0.05,      // $0.05: max optimization (200+ runs)
  'verify-source': 0.02,        // $0.02: Etherscan verification
  'deploy-testnet': 0,          // Free: testnet deployment
  'deploy-mainnet': 0.10,       // $0.10: mainnet deployment assist
  'gas-estimation': 0.005,      // $0.005: detailed gas analysis
  'security-scan': 0.25,        // $0.25: security vulnerability scan
  'audit-report': 5.00          // $5.00: basic audit report
});

const compiler = new PaywallBuilder()
  .service('solidity-compiler')
  .pricing(compilerPricing)
  .build();

Compilation Tiers

// Optimization levels
const optimizationLevels = {
  none: { runs: 0, cost: 0 },
  basic: { runs: 200, cost: 0.01 },
  standard: { runs: 1000, cost: 0.02 },
  maximum: { runs: 10000, cost: 0.05 }
};

// Compile with optimization
async function compileContract(
  source: string,
  settings: CompileSettings = {}
) {
  const optimization = settings.optimization || 'none';
  const config = optimizationLevels[optimization];

  if (config.cost > 0) {
    await compiler.charge(config.cost, { 
      type: 'compilation',
      optimization,
      runs: config.runs
    });
  }

  return SolidityCompiler.compile(source, {
    optimizer: {
      enabled: config.runs > 0,
      runs: config.runs
    },
    evmVersion: settings.evmVersion || 'paris'
  });
}

Source Verification

// Premium Etherscan verification
async function verifyOnEtherscan(
  address: string,
  source: string,
  constructorArgs: any[],
  chain: 'ethereum' | 'arbitrum' | 'base' | 'polygon'
) {
  await compiler.charge(0.02, { 
    type: 'verify-source',
    chain,
    address
  });

  return SolidityCompiler.verify({
    address,
    source,
    constructorArgs,
    chain,
    compilerVersion: 'v0.8.24',
    optimization: true,
    runs: 200
  });
}

Security Scanning

import { PayableAgent } from '@nirholas/x402-ecosystem/agent';

const agent = new PayableAgent({
  wallet: agentWallet,
  approvedServices: ['solidity-compiler'],
  dailyLimit: 20
});

// Premium security scan
async function securityScan(source: string) {
  await agent.pay({
    service: 'solidity-compiler',
    amount: 0.25,
    description: 'Security vulnerability scan'
  });

  return SolidityCompiler.securityScan(source, {
    checks: [
      'reentrancy',
      'overflow',
      'access-control',
      'oracle-manipulation',
      'front-running',
      'dos-vectors',
      'unchecked-return'
    ]
  });
}

// Basic audit report
async function generateAuditReport(source: string) {
  await agent.pay({
    service: 'solidity-compiler',
    amount: 5.00,
    description: 'Generate basic audit report'
  });

  const scan = await SolidityCompiler.securityScan(source);
  const gasAnalysis = await SolidityCompiler.analyzeGas(source);

  return SolidityCompiler.generateReport({
    source,
    securityFindings: scan,
    gasAnalysis,
    recommendations: true,
    format: 'pdf'
  });
}

Gas Analysis

// Premium gas estimation
async function analyzeGas(source: string) {
  await compiler.charge(0.005, { type: 'gas-estimation' });

  const compiled = await SolidityCompiler.compile(source);

  return SolidityCompiler.analyzeGas(compiled, {
    functions: true,        // Per-function gas costs
    deployment: true,       // Deployment cost
    optimization: true,     // Optimization suggestions
    comparison: true        // Before/after optimization
  });
}

Deployment Assist

// Premium mainnet deployment assistance
async function deployAssist(
  bytecode: string,
  abi: any[],
  constructorArgs: any[],
  chain: string
) {
  const isMainnet = !chain.includes('testnet') && !chain.includes('sepolia');

  if (isMainnet) {
    await compiler.charge(0.10, { 
      type: 'deploy-mainnet',
      chain 
    });
  }

  return SolidityCompiler.prepareDeployment({
    bytecode,
    abi,
    constructorArgs,
    chain,
    // Returns: encoded data, gas estimate, recommended gas price
  });
}
