How cold wallets work

Many people often misunderstand that wallets (hot and cold wallets) are places to keep and store users' cryptographic assets.

However, it must be understood that:

All cryptographic assets are stored on the blockchain network.

The wallet stores only the pair of public keys (representing the user's blockchain address) and the private key.

The only way to access cryptographic assets is through a specific private key for that public key.

Private keys allow users to authorize and sign transactions from addresses on the blockchain.

The main function of a cold wallet is to manage and protect users' private keys in an offline environment.

Therefore, it is not capable of interacting with decentralized applications (dApps) on its own and is suitable for long-term asset maintenance needs.

When needing to perform a transaction, the user must transfer the necessary amount from the cold wallet to the hot wallet.
A hot wallet will then be responsible for processing transactions and connecting to different dApps over the internet.
