Plain English

A hot wallet is a crypto wallet that stays connected to the internet. Browser extensions like MetaMask, mobile apps like Phantom, and exchange accounts are all hot wallets.

How it actually works

Hot wallets store private keys on devices that are routinely online. They prioritize convenience: one-tap signing, instant access, easy connection to DeFi. The trade-off is exposure — malware, phishing, browser exploits, and compromised devices can all reach a hot wallet’s keys.

What it means for you

Hot wallets are appropriate for spending money, active DeFi positions, and amounts you can afford to lose. They are not appropriate for long-term holdings. The line for most members: only what you would carry in cash should live in a hot wallet.

How ARCrypto teaches this

We cover hot-wallet hygiene — dedicated browsers, hardware-wallet pairing, transaction-simulation tools — for members who actively use DeFi without putting their full stack at risk.
