Step-by-Step Guide: Building a Coinbase Clone with Adalo

Building a Coinbase-style cryptocurrency exchange app presents a formidable challenge for entrepreneurs and startups. The technical requirements span user authentication, KYC verification workflows, real-time portfolio tracking, and secure transaction processing—systems that traditionally demand months of development time, specialized blockchain expertise, and significant financial investment.

That's where Adalo comes in. Adalo is a no-code app builder for database-driven web apps and native iOS and Android apps—one version across all three platforms. AI-assisted building and streamlined publishing enable launch to the Apple App Store and Google Play in days rather than months. This powerful combination lets you prototype and validate your crypto exchange concept rapidly, delivering the native mobile experience users expect while keeping development costs and timelines under control.

Why Adalo Is the Smart Choice for Building a Coinbase Clone

Adalo is a no-code app builder for database-driven web apps and native iOS and Android apps—one version across all three platforms, published to the Apple App Store and Google Play. This unified approach makes it ideal for cryptocurrency exchange apps, where users expect consistent access whether they're checking prices on their phone during a commute or executing trades from their desktop at home.

For a Coinbase-style app, native distribution through official app stores builds the trust that crypto users demand. Push notifications become essential for real-time price alerts, transaction confirmations, and security warnings—the kind of instant communication that keeps traders engaged and protected in volatile markets. With Adalo, you can deliver this polished, professional experience while rapidly prototyping your exchange concept without writing a single line of code.

Building a cryptocurrency exchange app traditionally requires months of development time, specialized blockchain expertise, and a substantial budget. From user authentication and KYC verification to portfolio management and transaction processing, the complexity of these interconnected systems presents a significant barrier for entrepreneurs and startups looking to enter the crypto space.

Adalo, an AI-powered app builder, changes this equation entirely. Build database-driven web apps and native iOS and Android apps from a single codebase—one version across all three platforms. AI-assisted building and streamlined publishing enable launch to the Apple App Store and Google Play in days rather than months. This means you can prototype and validate your Coinbase-style exchange concept rapidly, focusing on user experience and core functionality while leveraging external APIs for blockchain integration when needed.

Why Adalo Works for Building a Crypto Exchange App

Adalo creates true native iOS and Android apps alongside web apps from a single build. This cross-platform capability is essential for cryptocurrency applications, where users expect seamless access across their phones, tablets, and desktops without you maintaining separate codebases.

For a cryptocurrency app, native app store distribution matters. Users need push notifications for price alerts, transaction confirmations, and security updates—features that keep them engaged and informed in the fast-moving crypto market. With Adalo, you deliver that professional, native experience while prototyping your core exchange functionality quickly and cost-effectively.

This guide walks you through creating a cryptocurrency exchange-style app using Adalo's platform. While bespoke crypto exchanges can take months and substantial budgets, this AI-assisted approach lets you prototype core flows—registration, KYC capture, portfolio view, buy/sell orders (off-chain accounting), and payments—in weeks. Publish the same app to web, native iOS, and native Android without writing code or rebuilding anything.

Important: This guide implements a custodial/off-chain balance model in Adalo. On-chain deposits/withdrawals and blockchain signing/broadcasting require external services via External collections or Custom actions.

Setting Up Your Adalo Account for Crypto App Development

Step 1: Create Your Adalo Account

  1. Visit Adalo.com and sign up.
  2. Verify your email.
  3. Create New App → choose Mobile App.
  4. Name your project (e.g., "CryptoExchange").
  5. Start from Scratch (no crypto-specific template).

Ada, Adalo's AI builder, lets you describe what you want and generates your app. Magic Start creates complete app foundations from a description, while Magic Add adds features through natural language.

Alternatively, use Magic Start to generate a complete app foundation from a description. Tell it you need a cryptocurrency exchange app with user wallets and trading features, and it creates your database structure, screens, and user flows automatically—what used to take days of planning happens in minutes.

Step 2: Choose Your Plan

Review Adalo pricing for current plan features and publishing eligibility.

Unlike platforms with usage-based charges that create unpredictable bills, Adalo's paid plans include unlimited usage—no bill shock as your user base grows.

Step 3: Configure Your App Theme

Pick a trustworthy palette (navy/green), set typography, spacing, and corner radii, then continue into the builder.

Building the Database Structure

Adalo's database handles complex data relationships without record limits on paid plans. With the right data relationship setups, apps can scale beyond 1 million monthly active users—essential for a crypto exchange that might see rapid growth.

Step 4: Create the Users Collection

Database → Users → add properties:

Step 5: Create the Wallets Collection (Off-Chain)

+ Add Collection → "Wallets"

Step 6: Create the Transactions Collection

+ Add Collection → "Transactions"

Step 7: Create the Market Prices Collection

+ Add Collection → "Market Prices"

Step 8: Set Up Database Relationships

See the Database guide for detailed relationship setup.

Designing the User Authentication System

Step 9: Build the Welcome Screen

Logo + tagline, and buttons to Create Account and Login. Use Magic Add to add features by describing what you want—tell it "add a welcome screen with login and signup buttons" and it generates the components.

Step 10: Create the Sign Up Screen

Form (Users): Email, Password, Full Name, Phone, Country (+ Terms checkbox). Submit actions: Create User → navigate to KYC or dashboard.

Email verification: Implement via Custom actions or automation (e.g., SendGrid) using Adalo's tutorial: verification email. Configure it in your flow for production apps.

Step 11: Build the Login Screen

Email/Password → Login. If Two Factor Enabled is true → route to 2FA Verification.

Step 12: Implement Two-Factor Authentication (TOTP)

Create 2FA Setup and 2FA Verification screens.

See TOTP overview (industry standard). OWASP Mobile

Step 13: Create KYC Verification Flow

KYC Verification screen (Users update): document type/number, DOB, front/back images, selfie → set KYC Status = Pending and notify admin.

Compliance: In most jurisdictions, exchanges must implement KYC/AML and obtain required registrations/licensing. Requirements vary—consult regulators and counsel. FinCEN • FATF guidance

Creating the Cryptocurrency Dashboard

Step 14: Build the Main Dashboard

The Adalo 3.0 infrastructure overhaul (launched late 2025) makes apps 3-4x faster than before—critical for crypto dashboards where users expect instant price updates.

Step 15: Connect to Price APIs

Use External collections or API component to connect to CoinGecko. Endpoint: /coins/markets (vs_currency=usd, order=market_cap_desc).

Mapping (correct):

Refresh via a timer pattern or screen revisit.

Step 16: Create Portfolio Analytics

Portfolio screen: list user wallets with amount held, current value, % of portfolio, and 24h P/L. Add charts via Component marketplace.

Building Buy and Sell Functionality

Step 17: Create the Trading Screen

Tabs for Buy and Sell.

Step 18: Implement Order Processing

Validations: balance checks, KYC Status = Verified. On submit: create Transaction (Pending) → Order Confirmation → on confirm:

Step 19: Integrate Payment Processing (Fiat → App Balance)

Install Stripe or Marketplace Payments (for multi-party payouts). Configure keys and create a charge to fund USD balance; on success, complete the transaction flow.

Fees: In the U.S., online card pricing is typically 2.9% + $0.30 per successful charge; fees vary by country and payment method. Stripe pricing

Designing Wallet Features

Step 20: Build the Wallets Screen

List user wallets: icon, balance, USD value, and + to add a wallet record.

Step 21: Wallet Details Screen

Show coin name, balance, value, optional display address/QR (if using custody). Actions: Deposit, Withdraw, Transaction History.

Step 22: Deposit Flow (If Using External Custody)

Display "Send to this address" details returned by your custody API. Monitor incoming TX via External collections; on confirmations, update balance and notify the user.

Step 23: Withdrawal Flow (If Using External Custody)

Form: recipient address, amount, network fee, priority. Validate balance, run 2FA, call custody API via Custom actions, then update status as confirmations arrive.

Implementing Security Features

Step 24: Security Settings

Add toggles for 2FA, change password, and notification preferences.

Step 25: Rate Limiting (App Logic)

Track failed attempts in Users; lock after threshold and notify. (Business logic in Adalo database + actions.)

Step 26: Data Protection Notes

Adalo provides authentication and HTTPS; consult current materials for data-protection details and handle secrets carefully. See Mobile app security (OWASP) and Adalo's security best-practice content.

Do not store private keys in Adalo; use dedicated key management/custody.

Step 27: Activity Logs

Create an Activity Log collection (action, IP/device, time, status). Log sensitive actions and show a recent history screen. Use X-Ray to identify performance issues before they affect users as your logging data grows.

Testing Your Crypto Exchange App

Step 28: Create Test Data

Seed test users (KYC states, 2FA on/off), wallets, and transactions. Use Stripe test cards for payment tests.

Step 29: Test Core Workflows

Step 30: Performance Optimization

Compress images, limit list sizes, and cache price data. See Optimize performance and consider External collections for large datasets. Adalo's modular infrastructure scales with your app's needs—no arbitrary ceilings to hit.

Publishing Your Crypto Exchange App

Step 31: Prepare for Launch

Switch to production keys (Stripe, price data, custody), set push notifications, and add legal pages (Privacy, Terms, Risk, Fee schedule). Set up support flows.

Step 32: App Store Submission

Adalo handles the complex App Store submission process, so you focus on your app's features instead of wrestling with certificates, provisioning profiles, and store guidelines. Updates to published apps are unlimited on all paid plans.

Step 33: Web App Deployment

Configure a custom domain via web app publishing; set SSL and DNS, then test responsiveness. One build updates web, iOS, and Android simultaneously.
