A hot wallet is a cryptocurrency wallet that is connected to the internetsuch as a browser extension, mobile app, or desktop client. Hot wallets are convenient for day-to-day use, trading, and interacting with dApps and NFT marketplaces, but they carry higher security risk because they are more exposed to malware, phishing, and compromised devices.
By contrast, cold wallets (hardware wallets or air-gapped setups) keep private keys offline and are generally preferred for long-term storage of high-value funds and NFTs.
