When a crypto asset holder in their 50s wants to transfer assets to a spouse or children in preparation for sudden accidents or illness, there is no single source of information covering wallet passwords, seed phrase transfer methods, valuation for inheritance tax as of the assessment date, and inheritance application procedures that differ by exchange. It is even unclear how to report crypto assets on the National Tax Service inheritance tax return, so hiring a tax accountant costs 1-3 million KRW (approx. $750-$2,250) per case, and finding a tax accountant specializing in crypto assets is difficult.
On the web, users select their exchanges, wallet types, and asset types, and the service provides step-by-step: (1) inheritance application procedures and required document checklists by exchange, (2) inheritance tax base amount simulation (automatic calculation of valuation as of inheritance date), and (3) secure seed phrase and password transfer guides (including legally valid will templates). It compares tax scenarios based on the 2026 crypto asset taxation implementation standards.
