Sensitive Data Exposure\n\n#### Logging\n```typescript\n\u002F\u002F ❌ WRONG: Logging sensitive data\nconsole.log('User login:', { email, password })\nconsole.log('Payment:', { cardNumber, cvv })\n\n\u002F\u002F ✅ CORRECT: Redact sensitive data\nconsole.log('User login:', { email, userId })\nconsole.log('Payment:', { last4: card.last4, userId })\n```\n\n#### Error Messages\n```typescript\n\u002F\u002F ❌ WRONG: Exposing internal details\ncatch (error) {\n  return NextResponse.json(\n    { error: error.message, stack: error.stack },\n    { status: 500 }\n  )\n}\n\n\u002F\u002F ✅ CORRECT: Generic error messages\ncatch (error) {\n  console.error('Internal error:', error)\n  return NextResponse.json(\n    { error: 'An error occurred. Please try again.' },\n    { status: 500 }\n  )\n}\n```\n\n#### Verification Steps\n- [ ] No passwords, tokens, or secrets in logs\n- [ ] Error messages generic for users\n- [ ] Detailed errors only in server logs\n- [ ] No stack traces exposed to users\n\n### 9. Blockchain Security (Solana)\n\n#### Wallet Verification\n```typescript\nimport { verify } from '@solana\u002Fweb3.js'\n\nasync function verifyWalletOwnership(\n  publicKey: string,\n  signature: string,\n  message: string\n) {\n  try {\n    const isValid = verify(\n      Buffer.from(message),\n      Buffer.from(signature, 'base64'),\n      Buffer.from(publicKey, 'base64')\n    )\n    return isValid\n  } catch (error) {\n    return false\n  }\n}\n```\n\n#### Transaction Verification\n```typescript\nasync function verifyTransaction(transaction: Transaction) {\n  \u002F\u002F Verify recipient\n  if (transaction.to !== expectedRecipient) {\n    throw new Error('Invalid recipient')\n  }\n\n  \u002F\u002F Verify amount\n  if (transaction.amount > maxAmount) {\n    throw new Error('Amount exceeds limit')\n  }\n\n  \u002F\u002F Verify user has sufficient balance\n  const balance = await getBalance(transaction.from)\n  if (balance \u003C transaction.amount) {\n    throw new Error('Insufficient balance')\n  }\n\n  return true\n}\n```\n\n#### Verification Steps\n- [ ] Wallet signatures verified\n- [ ] Transaction details validated\n- [ ] Balance checks before transactions\n- [ ] No blind transaction signing\n\n### 10.
