# Crypto Portfolio Tracker iOS Template, Free and Read-Only > By Lawrence Arya, Founder & CEO of VP0.

Keep it read-only: track via public prices, never custody keys or seed phrases. **TL;DR.** A crypto portfolio tracker shows holdings, live prices, total value, and performance charts. Build it free from a VP0 design in SwiftUI, pull prices from a public market API, and keep it strictly read-only: track balances via manual entry or read-only public addresses, and never ask for, store, or custody private keys or seed phrases. Prototype with sample holdings, then connect a price API. Read-only and key-safe is the whole safety story. Building a crypto portfolio tracker for iOS? The short answer: it shows what you hold and what it is worth, and the single most important design choice is to keep it read-only. Track balances and pull public prices, but never custody keys or seed phrases. Build it free from a VP0 design, the free iOS design library for AI builders, in SwiftUI, and clone it into your AI tool. Read-only and key-safe is the whole safety story. ## Who this is for This is for builders making a crypto portfolio, holdings, or markets app who want live tracking and clean charts without paying for a kit, and who want to avoid the security and liability of handling keys. ## What a tracker has to get right, safely The features are straightforward: a holdings list, live prices, total portfolio value, allocation, and a performance chart over time. The safety model is what matters most. A tracker should be strictly read-only: let users add holdings manually or by a read-only public address, fetch prices from a public market API to value them, and never ask for, store, or transmit a private key or seed phrase. That removes the biggest risk entirely, you cannot lose what you never hold. The [Apple Human Interface Guidelines](https://developer.apple.com/design/human-interface-guidelines) cover the layout, [Swift Charts](https://developer.apple.com/documentation/charts) renders the performance graph, and a public API like [CoinGecko](https://www.coingecko.com/en/api) supplies prices. | Element | Job | Get it right | |---|---|---| | Holdings | What you own | Manual or read-only address | | Live prices | Value it | Public market API | | Total and allocation | The big picture | Clear, glanceable | | Performance chart | Show over time | Swift Charts | | Security | Protect users | Read-only, never custody keys | ## Build it free with a VP0 design You do not need a fintech kit, which can run $49 to $200. Pick a portfolio or dashboard screen in VP0, copy its link, and prompt your AI builder: > Build a SwiftUI crypto portfolio tracker from this design: [paste VP0 link]. A holdings list, live prices from a public market API, total value and allocation, and a performance chart with Swift Charts. Read-only only: add holdings manually or by read-only address, never ask for private keys. Match the palette and spacing from the reference, and generate clean code.

Track holdings by manual entry or by importing a read-only public address, and fetch prices from a public API to value them. The app never needs and never asks for a private key or seed phrase, which keeps users safe and you free of custody liability. Prototype with sample holdings and a stubbed price feed, then connect the real API, keeping any provider key behind a backend. Show clear total value, allocation, and a performance chart, and the tracker is genuinely useful without ever touching the one thing that could hurt users. ## Common mistakes The first mistake is asking for private keys or seed phrases; a tracker never should. The second is custodying funds, which adds huge risk. The third is no clear total or allocation, the reason people open a tracker. The fourth is a key embedded in the app for a paid price API. The fifth is paying for a kit when a free VP0 design plus Swift Charts does it. ## Key takeaways - A crypto tracker shows holdings, prices, total value, and performance. - Keep it strictly read-only: manual entry or read-only addresses, never private keys. - Pull prices from a public market API and chart performance with Swift Charts. - VP0 gives you the UI free, ready to build in SwiftUI with Claude Code or Cursor. - Read-only and key-safe removes the biggest security and liability risk. ## Frequently asked questions How do I build a crypto portfolio tracker app? Build holdings, live prices, total value, and charts from a public market API, in SwiftUI from a free VP0 design, keeping it read-only with no private keys. What is the best free crypto tracker template for iOS? VP0, the free iOS design library for AI builders, which generates clean SwiftUI for the holdings and charts from a design link. Should a tracker handle private keys? No. Keep it read-only, manual entry or read-only public addresses, and never ask for or store private keys or seed phrases. Where do crypto prices come from? From a public market data API such as CoinGecko. The app values holdings without wallet access; keep any API key behind a backend. ## Frequently asked questions ### How do I build a crypto portfolio tracker app?
