Partly, you can build the app, but real trading and crypto storage need an approved partner.
You can build a Coinbase-style app with coin prices, a portfolio and buy-and-sell screens. Real trades and holding customers' crypto need a licensed provider that approves your app and handles those services.
What keeps people on Coinbase:It moves real moneyPartner accessRegulation
The checker split your own version of Coinbase into its key parts and sorted each one.
Coin prices and portfolio
Vibecode can build price lists, charts and a portfolio screen using crypto price data.
Works out of the box
User accounts
Use Vibecode Cloud on Plus for login and saved account data.
Needs setup
Real buying and selling
You need approval from a licensed crypto trading provider, then Vibecode can build around its API.
Takes more work
Holding customers' crypto
Use an approved custody provider to hold assets and handle transfers rather than storing customers' private keys yourself.
Takes more work
Practice trading
Start with pretend money and simulated trades so you can test the app before connecting a provider.
Works out of the box
An iPhone app fits checking your balance and buying or selling on your phone.
Plan ahead: Choose a licensed partner first and confirm its approval, identity checks and regional rules before offering real trades or custody.
Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want to track crypto and practice buying and selling before using real money. The main screen should show a sample portfolio balance, coin holdings and a list of coin prices. Tapping a coin opens its price chart and Buy and Sell buttons. Those buttons should open a simple amount form and confirmation screen, then update the practice portfolio. Use realistic sample data and clearly label all balances and trades as simulated. Do not connect real wallets or accept money. Give it a clean navy and white design with readable numbers and simple navigation.

Coinbase provides licensed trading and custody, established banking connections, and an existing market of buyers and sellers that a homemade app would need approved partners to access.

Vibecode builds a first version from one prompt, and the checker would start with these parts: a coin list with sample prices and coin detail screens; a sample portfolio with balances; practice buy and sell flows using pretend money. Plan on a few weeks for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Coinbase, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year); API key for crypto trading and custody provider (that service's pricing).
Coinbase provides licensed trading and custody, established banking connections, and an existing market of buyers and sellers that a homemade app would need approved partners to access. A version you build yourself won't have these: Coinbase's financial licenses; established banking relationships; existing exchange liquidity; Coinbase's crypto custody operations.
