Exchange Trading Volume financial
"Exchange Trading Volume for a specific period is the total value"
Marketplace Trading Volume financial
"Marketplace Trading Volume for a specific period is the total value"
Total number or value of shares, contracts or other units bought and sold on a particular trading venue during a set period, usually a day. It shows how much activity and interest a marketplace or a specific security is drawing — like measuring foot traffic through a store — and helps investors judge how easy it will be to trade, how reliable price moves are, and whether a stock may swing wildly on small orders.
Customer Assets financial
"Customer Assets and Number of Verified Accounts correspond to figures"
Verified Accounts financial
"Verified Accounts are all accounts that have been opened after the account owner completes"
know your customer regulatory
"including “know your customer” or “KYC”), after subtracting therefrom"
Know your customer (often called KYC) is the routine process financial firms use to verify who their clients are and assess the risk they pose, by collecting identity documents, background information and transaction history. For investors, KYC matters because it determines whether you can open or maintain accounts, how quickly you can trade, and how a firm manages regulatory and fraud risk—similar to a landlord checking references before renting to someone.
non-fungible tokens financial
"Customer Assets do not include non-fungible tokens (NFTs)."
A non-fungible token is a unique digital certificate, stored on a blockchain, that proves ownership and authenticity of a specific digital item or a limited physical asset—think of it as a one-of-a-kind trading card or a deed for a piece of art. It matters to investors because it creates markets for scarcity and exclusive rights, with value driven by rarity, demand and transferable ownership, but it can be volatile and illiquid.

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.

Historically, Coincheck’s total revenue has been derived primarily from transactions on Coincheck’s marketplace platform business.
