The currency picker position on nexus market

The currency picker on the real nexus market is a small control in a fixed corner of the framed page. It is not a hero. It is not a floating chip. If the picker moves between two pages inside the same session, that is worth another beat.

What it is

The currency picker is the small toggle in the header that lets a reader switch the displayed prices between one currency and another. On the real page it is a compact control in a fixed corner of the header. It carries the current selection in short form and opens a small list when clicked. It does not carry a flag icon. It does not carry a coloured badge with the word new next to it. The reader is expected to know what the toggle is for without a caption.

Shape of the picker

Position

A fixed corner of the header. Not the centre. Not a floating chip attached to the row. Not a modal.

Label

The short form of the current selection, drawn in the same face as the rest of the header.

Menu

A small list, opened on click. Not opened on hover. Not opened on page load.

Feedback

A quiet redraw of the prices below. Not a full page reload. Not a toast at the top of the screen.

What a lookalike tends to add

• A flag icon next to the label. Flags on a currency picker read as marketing, and marketing on a small header control is a signal.
• A coloured chip with the word new or promoted next to a currency the reader has never picked. The chip is trying to move the reader by default.
• A picker that opens on hover, sometimes closing under the cursor. The extra motion is a way to keep the reader engaging with the control.
• A modal that opens over the page and asks the reader to pick a currency before the page will finish loading. The real page does not gate the read behind a picker.

Why the position holds

A fixed position for the picker lets the reader ignore it once they have set it. On the real page the toggle is a preference the reader sets and forgets. On a page that has been built to imitate the real one, the imitator often reaches for the toggle as a place to attract the eye, because the toggle is one of the few controls the imitator understands well enough to redraw. The busier the toggle, the more likely the imitator is behind the redraw.

How a reader checks this

The reader opens two pages inside the frame in a single session and looks at the corner where the picker lives. If the picker is in the same corner on both, and it holds the same short label on both, that matches. If the second page has the picker in the centre of the header, or carrying a coloured chip it did not carry on the first page, that is worth another beat.

What this pairs with

The currency picker position pairs with the wordmark position and the deposit address panel shape. All three are quiet structural signals. A page that has drifted on one has usually drifted on the other two, and a reader who checks the three together spends less than a minute doing so.

Engagement

What this card does not claim

• It does not name the currencies on the list. That list is not part of the shape and can move on a rebuild.
• It does not treat a picker with a chip as proof of a fake. A rebuild can add a chip and the site does not know a rebuild has not happened.
• It does not say where the picker sits on a phone-sized viewport. Small viewports rearrange headers by design.
