💬 Example Prompts for AI Assistants

Wallet Management:

"Create a new Casper wallet for me"
"What's my CSPR balance?"
"Check the balance of wallet 01abc123..."
"Show me my Casper account details"

Transfers:

"Send 100 CSPR to wallet 01abc123..."

🔒 Security

🛡️ Security Best Practices

• Private Key Protection - Never commit .env files or private keys to version control
• Environment Variables - Store sensitive data (API keys, private keys) in environment variables
• API Key Security - Keep your cspr.cloud API key secure and don't share it
• Input Validation - All public keys and amounts are validated before processing
• Mainnet Caution - This server operates on Casper mainnet with real CSPR tokens
• Error Handling - Errors don't expose sensitive wallet information
• Secure Communication - All RPC calls use HTTPS to cspr.cloud
