Notes
●Exchange Trading Volume for a specific period is the total value, based on the underlying asset, of all transactions completed through Coincheck’s exchange platform. Coincheck’s exchange platform facilitates buy and sell transactions directly between two parties (a buyer and a seller) for which, generally, Coincheck charges no fee. Coincheck sometimes is a buyer on the exchange platform to help support transaction activity on the marketplace platform.
●Marketplace Trading Volume for a specific period is the total value, based on the underlying asset, of all transactions completed through Coincheck’s marketplace platform business. Historically, Coincheck’s total revenue has been derived primarily from transactions on Coincheck’s marketplace platform business. For additional details, please see Coincheck Group N.V.’s filings with the U.S. Securities and Exchange Commission.
●Customer Assets and Number of Verified Accounts correspond to figures as of the end of each month. Verified Accounts are all accounts that have been opened after the account owner completes all application procedures (including “know your customer” or “KYC”), after subtracting therefrom the total number of closed accounts.
●Customer Assets are cryptocurrencies held for customers + fiat currency deposited by customers. Customer Assets do not include non-fungible tokens (NFTs).
●Prior monthly numbers, which are generally preliminary at the time of initial publication, may have been updated by immaterial amounts.
