Background | 'Assumed Management' No Longer Suffices

Corporate crypto holdings continue to expand as part of treasury strategies. The regulatory environment is also shifting. In April 2026, the Cabinet approved a bill to amend the Financial Instruments and Exchange Act to regulate crypto assets, anticipating insider trading regulations. The standard of management required for corporate crypto transactions will inevitably rise.

A commonly overlooked issue is that cryptocurrency management issues do not surface during daily operations; transaction execution itself works fine. The difficulty arises during audits or year-end closing when companies must prove 'who, when, with what authority, and why' a transaction was made.

If any of the following apply, your organization may already face this risk:

- Transaction records are scattered across Excel, chat logs, exchange logs, and wallets. - Transaction approvals are completed verbally or via chat, leaving no audit trail. - Cost basis calculations are manual and dependent on a single individual. - Staking and node reward journal entries are processed in bulk right before closing. - Lack of confidence in answering an auditor immediately about who initiated a remittance and why.

Among the companies supported by the Company, the issues were often realized only after auditor feedback or staff turnover.

Meanwhile, existing options have been polarized. Overseas enterprise custody platforms offer high functionality but come with heavy deployment and operating costs, which is over-engineered for firms holding smaller amounts of crypto assets. Conversely, managing via Excel and manual processes will not withstand upcoming audit and regulatory standards.

'CRYPTO Governance' fills this gap for companies that do not need full enterprise infrastructure but still require control. Starting with a minimum configuration of 5,000 JPY per month, companies can combine only the necessary features and expand coverage as their business grows.

What is 'CRYPTO Governance'?

It packages five core features across pre-transaction, mid-transaction, and post-transaction phases into a single system, ensuring a continuous audit trail from request and approval to accounting journal entries.

- Pre-transaction ①: Transaction Limit Management: Enables execution only within a whitelist specifying currency, amount limit, destination, and expiration date. - Pre-transaction ②: Approval Flow: Enforces Segregation of Duties (SOD) systematically. Supports tier-based approval workflows for prompt authorization in 24/7 markets. - Mid-transaction ③: Real-time Monitoring: Provides cross-monitoring of CEX, DEX, wallets, and node assets on a single screen. Alerts are triggered instantly for off-limit transactions. - Mid-transaction ④: Transaction Execution: Executes only approved transactions via API. Unapproved or off-limit orders are blocked at the system level. - Post-transaction ⑤: Accounting & Evidence: Automatically calculates cost basis (moving average method), realized gains/losses, and various rewards, and integrates with services like freee and Money Forward.

Based on packaged features, customized solutions are delivered to fit each company's actual operations. It supports diverse business models including Digital Asset Treasury (DAT), node operations, and token holdings.

Key Feature 1: Transactions Never Exceed 'Approved Limits'

Users can pre-register transaction limits by specifying currency, maximum amount, connected exchange, recipient address, and expiration date. Transaction execution is allowed only within these boundaries. Any off-limit transaction is instantly detected and alerted via Slack or email. Rather than detecting unauthorized transfers after they happen, it blocks them beforehand.

Key Feature 2: Approved Details Match Executed Details

Separating system approvals from manual execution by operators often leads to discrepancies, human errors, and tampering. In 'CRYPTO Governance,' only transactions that have passed the approval workflow are executed via API. Execution logs are automatically linked with approval logs and saved in an immutable format. Private keys are kept in the customer's own environment, removing any need to deposit them with the Company.

Key Feature 3: Automated Journal Entries and Audit Materials

It automatically calculates the acquisition cost (moving average method) and realized gains/losses from transaction histories.
