Sweeper (Balance Cleaner)
Keep hot wallets lean and safe by automatically sweeping coins and tokens to your cold treasury. This page explains how the sweeper is started, how it decides what to move, and which parameters control its behavior.
What the sweeper does
Iterates over all active hot addresses in the payment system, checks balances, and tries to move funds to cold addresses.
Coins (native assets): sent via a normal transfer; gas is paid by the sending address.
Tokens (e.g., ERC-20/TRC-20): require native coins on the source address to pay gas, so the sweeper first tops up a small amount of native coin to that address, then sends the tokens to cold storage.
