Your wallet sleeps when you do.
Every Solana transaction is timestamped. Plot a wallet's activity by hour and a quiet window appears — usually the owner's night. From that, anyone can guess the time zone. Paste a wallet to see what its timing gives away.
Paste an address above. We read up to 1,000 signatures (timestamps), then check which of the newest 400 this wallet actually signed. 2–10 seconds.
Timing is a fingerprint you cannot see.
On its own, a time zone is weak. Combined with a social account that posts at the same hours, or another wallet with the same rhythm, it narrows things down quickly.
Why it works
People transact while awake. Over a few weeks the gap where they sleep shows up clearly, and the midpoint of that gap sits around 3–5 a.m. local time for most people.
Linking wallets
Two wallets with the same quiet window, weekday pattern and busy hours look like one owner, especially if they also share counterparties.
Scheduled actions
Recurring buys, limit orders and DCA run on a schedule, not your clock. Using them for routine moves blurs the pattern.
Irregular timing
For a wallet you want kept separate, avoid using it in the same sessions as your main wallet, and do not move funds between them back-to-back.
