Hot Wallet
A crypto wallet connected to the internet, convenient for frequent transactions but exposed to malware, phishing and remote theft.
What Hot Wallet means
A hot wallet holds private keys on a device that is online: a browser extension, a mobile application, a desktop program, or the custodial wallet an exchange maintains on a user's behalf. Keys are available to sign transactions immediately, which makes hot wallets the practical choice for trading, paying fees, interacting with DeFi protocols and moving funds quickly. Self-custodial hot wallets keep the key under the user's control; custodial ones do not, and the distinction determines who actually owns the assets.
Convenience is the entire point. Connecting a browser wallet to a protocol takes seconds, transfers confirm in minutes, and no physical device is needed. That same connectivity is the vulnerability. Malware and keyloggers can read keys or seed phrases from a compromised machine, phishing sites imitate legitimate applications to capture a seed, malicious token approvals can grant a contract permission to drain a balance later, and clipboard hijackers substitute an attacker's address at the moment of transfer.
The workable discipline is to treat a hot wallet as a spending account rather than a vault. Keep only the balance needed for near-term activity, hold long-term positions in cold storage, and review and revoke token approvals periodically. Never type a seed phrase into a website under any circumstance, since no legitimate application asks for it. Where a custodial exchange wallet is used, remember that the assets are an obligation of that firm and are exposed to its solvency and security, not just your own.
Worked example
A trader might keep 500 USD of ether in a browser wallet to pay gas fees and interact with protocols, while the remaining holdings sit on a hardware wallet that is only connected when a large transfer is deliberately made.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
