know your customer regulatory

"Verified Accounts are all accounts that have been opened after the account owner completes all application procedures (including “know your customer” or “KYC”)"

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 technical

"Customer Assets do not include non-fungible tokens (NFTs)."

●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.
