Spent Volume Age Bands (SVAB) is a separation of the on-chain transfer volume based on the coins' age. Each band represents the percentage of spent volume that was previously moved within the time period denoted in the legend. This metric is entity-adjusted and discards transactions between addresses of the same entity ("in-house" transactions).

Entities are defined as a cluster of addresses that are controlled by the same network entity and are estimated through advanced heuristics and Glassnode's proprietary clustering algorithms. Note that entity–based metrics are based on data science techniques and statistical information that changes over time and are therefore mutable – the data is stable, but most recent data points are subject to slight fluctuations as time progresses.
