Gap Limit Management
Gap Limit Management is the practice of setting a threshold for how many unused addresses a wallet will scan before stopping its search for incoming funds. Because wallets derive addresses in a sequence, they need a way to know when to stop looking for new transactions.
The gap limit, typically set to 20, ensures that the wallet finds all addresses that have been used, even if some were skipped. If a user generates more than the gap limit of unused addresses, the wallet might stop scanning and fail to detect future transactions.
This is a common issue for users who use many addresses or have complex transaction patterns. In the context of systems risk, proper gap limit management prevents the loss of visibility into assets.
It is a technical constraint that users must understand to ensure their wallets function correctly. By managing this limit, software developers provide a balance between synchronization speed and reliability.
It is a critical, albeit often hidden, part of the wallet's operational logic.
