Why use it. The headline size of a coin, the figure coins are ranked by. How to read it. It moves with the price day to day; supply changes move it slowly. Compare it with Fully Diluted Valuation to see how much supply is still to come.

Calculation. Hourly closing price of CryptoKeyhole's own ARB/USD index of public exchange markets x the circulating supply. Published supply, not node-verified: Arbitrum Foundation supply method, with the ArbitrumDAO treasury read from Arbitrum One's public RPC (https://docs.arbitrum.foundation/token-supply), the Arbitrum Foundation's method: 10 billion ARB less the ArbitrumDAO treasury's balance and less the team, investor and Foundation allocations not yet unlocked under their published schedules (unclaimed airdrop ARB returned to the treasury counts as treasury here).
