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.
