DATX X-Wealth — AI stock-investing app

X-Wealth is DATX's consumer fintech app — turning dense market data into clear signals, rankings and portfolios, with copy-trading and an AI Broker, for 10,000+ Vietnamese retail investors. The v2 work rebuilt the app on a tokenised design system.

DATX X-Wealth — AI stock-investing app
The challenge

Retail investors face overwhelming, jargon-heavy market data — and in trading, a misread number costs money. The v1 app's inconsistent UI and weak colour contrast hurt both trust and accessibility. It needed a calmer, decision-first interface and a scalable system across eight feature areas.

01UX Research & IA

I mapped the investor decision journey — watch, read the signal, decide, then copy or trade — and structured eight feature areas around it.

  • Organised the app into clear areas: overview, signals, rankings, portfolio, copy-trade, AI broker, research and pricing.
02Design System

I rebuilt the product on design tokens and fixed the colour system to meet accessibility contrast — so the app scales consistently and reads correctly under pressure.

  • Tokenised colour, type and spacing; reset the palette for WCAG contrast; wrote the design principles.
03UI Design

A data-dense but calm interface that turns market noise into glanceable signals and rankings, with status-driven colour.

  • Designed high-fidelity flows for signals, copy-trade and the AI broker.
Approach
  1. 01

    Discover

    Mapped how retail investors actually decide — where the data overwhelms and trust breaks.

  2. 02

    Systemise

    Rebuilt the app on design tokens and an accessible colour system so eight feature areas stay consistent.

  3. 03

    Design

    Designed the decision-first flows across signals, portfolio, copy-trade and the AI broker.

Key decisions

Design tokens before screens

Rebuilding on tokens made eight feature areas consistent and far faster to extend — the system did the heavy lifting.

Fix colour for trust

I redid the palette for WCAG contrast because in trading a misread figure costs real money — accessibility here is a trust feature.

Two token tiers, on purpose

Benchmarked Spectrum, Polaris, Carbon and Fluent v2, then shipped only reference + system tokens — skipping the full four-tier model — to rebuild eight feature areas fast without over-engineering.

Switchable real / demo, one UI

After studying eToro, Mitrade, Coinbase, Bybit and OKX, I met the board's 'merge demo and real accounts' ask with a switchable mode behind an identical interface — satisfying stakeholders without confusing investors.

Outcome
  • Order completion 65% → 82%
  • Referrals drove 30% of signups — CAC down ~70%
  • Served 10,000+ investors / 8,000+ DAU; app rated 4.6/5
Reflection

In fintech, clarity is the product. A tokenised system and an accessible colour palette turned a noisy, jargon-heavy app into a calm decision tool — and proved that accessibility and trust are the same thing here.
