Implementation Guidelines

Secure Wallet Connection

import { useLaserEyes, WalletConnectionOptions } from '@omnisat/lasereyes-react'

function SecureWalletConnect() {
  const { connect } = useLaserEyes()

  const secureConnect = async () => {
    const options: WalletConnectionOptions = {
      requiredPermissions: ['SIGN_TRANSACTIONS'],
      networkValidation: true,
      timeout: 30000,
      onPermissionRequest: (permissions) => {
        // Validate requested permissions
        return validatePermissions(permissions)
      }
    }

    try {
      await connect(options)
    } catch (error) {
      // Handle connection errors securely
      handleSecurityError(error)
    }
  }
}

Secure Transaction Handling

import { useLaserEyes, TransactionSecurity } from '@omnisat/lasereyes-react'

function SecureTransaction() {
  const { sendBitcoin } = useLaserEyes()

  const secureSend = async (recipient: string, amount: number) => {
    const security = new TransactionSecurity({
      validateAddress: true,
      validateAmount: true,
      requireConfirmation: true,
      maxFeeRate: 100, // sat/vB
      minimumChange: 1000 // sats
    })

    try {
      // Validate transaction parameters
      await security.validate({ recipient, amount })

      // Send transaction with security checks
      const txid = await sendBitcoin({
        recipient,
        amount,
        security
      })

      // Verify transaction broadcast
      await security.verifyBroadcast(txid)
    } catch (error) {
      // Handle security violations
      handleSecurityViolation(error)
    }
  }
}

Privacy Protection

import { useLaserEyes, PrivacyConfig } from '@omnisat/lasereyes-react'

function PrivacyProtection() {
  const privacyConfig: PrivacyConfig = {
    maskAddresses: true,
    hideBalances: true,
    preventTracking: true,
    secureStorage: {
      encryption: true,
      autoClear: true,
      storageKey: 'secure_storage'
    }
  }

  return (
    <LaserEyesProvider
      config={{
        privacy: privacyConfig,
        network: MAINNET
      }}
    >
      <YourApp />
    </LaserEyesProvider>
  )
}

Security Best Practices

Input Validation

Always validate and sanitize user inputs, especially addresses and amounts, before processing transactions.

Error Handling

Implement secure error handling that doesn't expose sensitive information in error messages.

Network Security

Use secure connections (HTTPS) and validate network responses to prevent man-in-the-middle attacks.

Data Protection

Encrypt sensitive data at rest and in transit, and implement secure storage practices.

Security Checklist

Secure Key Management

Never store private keys in localStorage or expose them in the frontend.

Transaction Validation

Implement multiple validation layers for all transactions.

Access Control

Implement proper permission checks and wallet authentication.

Privacy Measures

Protect user data and implement privacy-preserving features.
