This guide explores their functionality, security risks, and best practices for safe usage.

How Hot Wallets Work
Hot wallets operate through two core components:
1. Public Keys: Wallet addresses (like account numbers) for receiving funds.
2. Private Keys: Secret codes granting access to assets—never share these!
Transaction Process
- Initiate: Enter recipient’s public key and amount.
- Verify: Confirm details (e.g., gas fees for Ethereum).
- Execute: Transaction broadcasts to the blockchain.
Note: Hot wallets store private keys online, making them vulnerable to hacking compared to offline cold storage.
