# How much is safe to keep in a hot wallet URL: https://www.caijing188.com/how-much-in-a-hot-wallet/ Published: 2026-10-17T18:09:39+08:00 | Updated: 2026-10-27T22:10:00+08:00 Verified: 2026-10-27 ## Quick answer A hot wallet should hold only what you are willing to lose in a single signing mistake, because the browser session is the attack surface. Separation of spending and savings matters more than the specific wallet brand. ## Summary Size it as money you would not miss this month. The browser is the attack surface, not the chain. ## Key takeaways - Cap the hot balance as a monthly figure. - Keep savings behind a hardware signer. - Rotate the spending wallet periodically. ## FAQ Q: Is a hardware wallet immune? A: No. It protects the key from extraction, not from you approving a malicious transaction on a compromised screen or with blind signing enabled. Q: Does a separate browser profile help? A: It reduces cross-site exposure and extension permission creep, which is a meaningful share of real incidents.
