Labeling cold wallets beside exchange accounts

Teams often import exchange balances cleanly and then drop a hardware-wallet total into the same column as trading inventory. The portfolio ledger then implies those coins can be sent to meet a margin call this afternoon. They cannot.

Separate labels, same book

Keep cold wallets on the ledger so net wealth stays visible, but give them a label that blocks accidental “available” math. Our import desktop treats labeled external wallets as confirmation lines: you refresh them deliberately, usually with an explorer check or a signed balance note, rather than a live exchange connector.

What goes wrong without labels

Without a cold label, a quarterly review may treat a long-term reserve as free float. With a label but no periodic confirmation, the ledger quietly ages. Neither failure is exotic; both appear in Hong Kong desks that grew faster than their bookkeeping habits.

A minimal ritual

Once per reconciliation window, open the cold address, note the balance and block height or confirmation time, and update the ledger line. Record who checked it. That single habit prevents most cold-wallet surprises we see during period close.
