The sum count of unique wallets that were active in the network as a sender of funds. All unique wallets that have sent funds in transactions are counted. This metric does not double-count wallets. In other words, if a wallet has been deemed active by sending funds, it is not counted again if it sends funds again during the same time interval. Wallets represent groups of addresses that we estimate are owned by the same entity. They provide a better proxy for user behavior since users often own more than one blockchain address.
