Seoul · Family Vault Record-Keeping

Offline ledgers for Ethereum and stablecoin family reserves

We help households document cold-wallet holdings, reconcile stablecoin balances, and prepare heir-ready vault records — entirely on paper and local files, without exposing keys online.

Bound ledger and archival folders on a wooden desk

Concrete records for real holdings

Ethereum address ledgers

Indexed lists of wallet addresses, derivation notes, and last-known on-chain balances copied during your session — never your private keys.

Stablecoin reserve sheets

USDT, USDC, and other fiat-pegged balances reconciled against exchange statements and cold-storage attestations you bring to the office.

Heir handover binders

Step-by-step recovery instructions, contact lists, and quarterly update schedules formatted for family members who do not trade daily.

Family Vault Ledger Setup

A four-hour in-office session where we build your household's offline record system: address index, reserve reconciliation worksheet, and a signed cover sheet listing what each document contains.

You leave with a numbered binder, duplicate copies for a second location, and a written schedule for the next quarterly review.

Households who keep offline vault records

"Our three adult children finally have a binder that explains which Ledger holds the family ETH and where the quarterly USDC tally lives. The session took one afternoon — longer than I hoped, but thorough."

— Min-jae H., Gangnam, ledger setup client

"The reconciliation worksheet caught a duplicate address entry we'd carried for two years. Small fix, but it saved confusion during our trust attorney review."

— Eleanor W., Seocho, quarterly review
