Reading room

A street-level room with two desks and one meeting table.

The library sits on Insam-ro in Geumsan-eup. You come for a booked desk, a Saturday workshop, or to collect a printed brief. Walk-in browsing of the shelves is welcome on staffed days when a session is not using both desks.

A single window desk with a closed notebook, pencil, and glass of water

Hours

Tuesday to Friday 10:00–18:00
Saturday 10:00–16:00. Workshop days use 10:00–13:30 at the back table.
Sunday and Monday Closed

Times are Korea Standard Time.

What is on the shelves

The shelves hold printed field lists for the mint account and the token account, a one-page order of SPL Token instructions from initialize mint through close account, and a short glossary we amend when the same question shows up three weeks running. Spines are plain. You write in your own notebook. The sheets stay in the room unless they were printed for your brief.

How a first visit goes

You book before you travel. On the day, you are met at the desk by the window. Coats go on the hook, phones stay silent, and the seed phrase stays at home. Han or Min-jae confirms the addresses you sent. Water is on the table. The session then follows the shape described on its own page, rather than a tour of the building.

If you are early for a Saturday workshop, the front desk is yours until 9:50. At 10:00 the back table starts, and late arrival after the mint-authority opening means we ask you to take the next Saturday so the group is not split.
