Overview

01 · The brief

Nanovest's shelf already held gold, crypto, and US stocks under one wallet. Foreign Stocks adds Hong Kong and mainland China listings to that same shelf, so an Indonesian investor buys a Shenzhen-listed stock the same way they already buy Apple.

Problem

02 · Where it broke

The shelf stopped at the US border.

Nanovest already sat as one wallet under gold, crypto, and US stocks, all read from a single balance. But an investor reading about a Hong Kong tech rebound or a Shenzhen-listed name had nowhere to act on it inside the app: those tickers simply didn't exist in Nanovest, so the only route out was a separate broker, a separate KYC, a separate account to remember.

The company's own roadmap made the shape of the gap obvious: all-in-one only meant something if the assets people actually wanted, not just the ones already built, lived under that one roof.

Approach

03 · How I worked

New markets, the same shelf.

Foreign Stocks became a row of tabs, not a new app section: US Stocks, HK Stocks, CN Stocks, and Gold sit inside one screen with a shared portfolio chart underneath, so switching markets is a tap, not a new place to learn.

Each market keeps its own index widget above the fold (HSI, HSCI, HSTECH for Hong Kong), so someone can read the mood of a market before opening a single stock. The stock detail and limit-buy screens carry over almost unchanged from the earlier US stocks case, quick-offset price chips included, so an HK$ order feels exactly as familiar as a US one already did.

What actually changed underneath was surfaced in one place, not spread across the whole flow: a processing screen with a world map names what's happening, a rupiah wallet routing through a foreign-exchange leg before it reaches a Hong Kong-listed share, so the extra second or two reads as visible progress, not a stall.
