Notes

●	Exchange Trading Volume for a specific period is the total value, based on the underlying asset, of all transactions completed through<br>Coincheck’s exchange platform. Coincheck’s exchange platform facilitates buy and sell transactions directly between two parties<br>(a buyer and a seller) for which, generally, Coincheck charges no fee. Coincheck sometimes is a buyer on the exchange platform to help<br>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<br>through Coincheck’s marketplace platform business. Historically, Coincheck’s total revenue has been derived primarily from<br>transactions on Coincheck’s marketplace platform business. For additional details, please see Coincheck Group N.V.’s filings<br>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<br>that have been opened after the account owner completes all application procedures (including “know your customer” or “KYC”),<br>after subtracting therefrom the total number of closed accounts.
---	---
●	Customer Assets are preliminary figures prepared in accordance with Japanese generally accepted accounting principles (JGAAP) and<br>differ from the financial figures of Coincheck Group N.V., prepared in accordance with International Financial Reporting Standards (IFRS),<br>and may be revised in the future.
---	---
●	Prior monthly numbers, which are generally preliminary at the time of initial publication, may have been updated by immaterial amounts.
