 the existence of and the Company’s rights to crypto assets held (current assets) for its own account in cold wallets, and the assessment of the Company’s obligation to safeguard crypto assets held on behalf of its customers in cold wallets as a critical audit matter. A high degree of auditor judgment was required to determine the nature and extent of the procedures performed and audit evidence obtained to evaluate the existence of and the Company’s rights to crypto assets held (current assets) for its own account in cold wallets, and the assessment of the obligation to safeguard crypto assets held on behalf of its customers in cold wallets, as control over these crypto assets is provided through private keys. The following are the primary procedures we performed to address this critical audit matter. We involved IT professionals with specialized skills and knowledge, who assisted in: •evaluating the design of certain internal controls over the existence of and the Company’s rights to crypto assets held in cold wallets, as well as testing the operating effectiveness of certain of these controls, including controls related to access management, segregation of duties across certain processes connected with the holding of crypto assets in cold wallets, and management’s reconciliation of internal records to public blockchains •comparing the Company’s records of select crypto assets held in cold wallets to the records on public blockchains using software audit tools •evaluating the reliability of audit evidence obtained from public blockchains and •obtaining evidence that management had control of the private keys required to access the crypto assets held in cold wallets by observing the movement of crypto assets in the blockchain, using the related private keys, and comparing to the Company’s internal records for a selection of crypto asset transactions. We evaluated the nature and extent of audit evidence obtained by assessing the results of procedures performed over the existence of and the Company’s rights to crypto assets held in cold wallets and the assessment of the obligation to safeguard crypto assets held on behalf of its customers in cold wallets. /s/ KPMG AZSA LLC We have served as the Company’s auditor since 2018.
