What is Hot vs Cold Wallet?

Hot and cold describe how exposed a wallet is to the internet. A hot wallet, such as a mobile or browser wallet, is always online, making it convenient for daily use but more exposed to hacks. A cold wallet stays offline, such as a hardware device kept disconnected, offering stronger protection for savings you rarely touch.

This matters because it lets you match security to purpose. Small spending amounts can live in a hot wallet, while the bulk of your holdings sit in cold storage where remote attackers cannot easily reach them.

Example: you keep a little crypto in a phone wallet for quests and swaps, and store your long-term savings on a hardware wallet locked in a drawer.

Safety note: never keep large balances in a hot wallet you use for connecting to random apps, since a single malicious token approval or drainer site can empty it. Splitting funds between a well-secured cold wallet and a small hot wallet limits the damage any single mistake can cause. Related terms include hardware wallet, cold storage, wallet-drainer, and self-custody.
