Definition. The number of unique addresses active in the network as a sender or receiver. Number of Sending Addresses and Number of Receiving Addresses are the sender and receiver subsets, and Number of Active Addresses (with contracts) also counts contract calls.

Technical. Only addresses active in successful transactions are counted. For BTC and DOGE, coinbase (miner reward) receivers are not counted. For ETH tokens, the zero address is counted as the sender of mints and the receiver of burns. For TON, the Elector and Config system contracts are excluded.
