A cryptocurrency wallet connected to the internet for easy access — convenient for daily use but more vulnerable to hacking.
A hot wallet is a cryptocurrency wallet that is connected to the internet, providing easy and immediate access to your digital assets for trading, DeFi interactions, and transactions. Common hot wallets include browser extensions (MetaMask, Phantom, Rabby), mobile apps (Trust Wallet, Rainbow), and desktop applications. Hot wallets offer maximum convenience — you can interact with dApps, execute trades, and manage your portfolio instantly. However, their internet connection makes them vulnerable to phishing attacks, malware, keyloggers, and other remote attack vectors. Best practice is to keep only the funds you actively need in hot wallets (typically less than 10% of your total crypto holdings) and store the rest in cold storage. Advanced users often use multiple hot wallets — a 'burner' wallet for interacting with new or unverified dApps, and a primary wallet for trusted protocols.
Hot wallets are cryptocurrency wallets connected to the internet — including browser extensions (MetaMask, Phantom), mobile apps (Trust Wallet, Coinbase Wallet), and desktop applications. They provide immediate access for trading, DeFi interactions, and daily transactions, making them the default choice for active crypto users. The trade-off is security: internet connectivity exposes hot wallets to phishing attacks, malware, browser vulnerabilities, and social engineering. The most common attack vector is malicious transaction signing — users are tricked into approving smart contract interactions that drain their wallet. Best practices include using a separate 'burner' wallet with limited funds for interacting with new or unverified protocols, revoking unnecessary token approvals regularly (through tools like Revoke.cash), and never storing your seed phrase digitally. Many experienced users employ a multi-wallet strategy: hot wallet for daily DeFi activity with small amounts, cold wallet for long-term storage of significant holdings.
A DeFi user keeps $500 in MetaMask for daily swaps and yield farming, while their main holdings of $50,000 are stored on a Ledger hardware wallet — if their MetaMask is compromised through a phishing attack, they only risk the smaller hot wallet balance.
Only what you actively need for trading and DeFi interactions — treat it like cash in your physical wallet rather than your savings account. For larger holdings, transfer to a hardware (cold) wallet. A common rule of thumb: if losing the amount in your hot wallet would significantly impact you, move most of it to cold storage.
