Crypto-Alerts is a lightweight, real-time monitoring platform that lists popular cryptocurrencies, exposes an expanded coin directory with sortable metrics, and lets registered users create multi-criteria alerts delivered by SMS or email. Users can track price thresholds, percentage-based triggers relative to 24-hour ranges, and manage alerts from a single account dashboard.

The Challenge

Never Miss a Move.

Traders and crypto enthusiasts need timely, actionable notifications across many coins without constant manual monitoring. Existing tools are often noisy, slow, or fragmented across channels, making it hard to react to rapid market moves.

The Solution

A focused web platform that surfaces top coins for quick market overview, provides a searchable, sortable coin directory, and enables account-based alert rules. Users create alerts for price above/below thresholds or within a percentage of the 24-hour high/low, and receive notifications via SMS or email when conditions are met.

Core Features

• Curated homepage listing of the most popular coins for instant market view
• Expanded coin directory with sorting and filtering by name, price, percent change, 24-hour high/low range, and market share
• Account creation and management for personalized alert rules
• Flexible alert criteria: price above/below thresholds or within a percentage of 24-hour high/low
• Multi-channel delivery: SMS and email notifications
• Alert management UI: create, edit, disable, and review alert history

Technical approach

Real-time price feeds and periodic polling compute live metrics and 24-hour ranges. A scalable alert engine evaluates user rules against incoming data and dispatches notifications through integrated SMS and email providers. The UI provides fast search and sorting for large coin lists and a secure account system for managing alerts.

The architecture separates data ingestion, rule evaluation, and notification delivery to ensure reliability under load and to make it straightforward to add new delivery channels or data sources.

Business impact

• Faster reaction times for users who need to act on price moves
• Higher engagement through personalized, multi-channel alerts
• Improved retention by centralizing a user's alert rules and history
• Scalable alerting that supports many users and many coins without manual oversight

Crypto-Alerts brings clarity and speed to a fast-moving market, giving users the power to track the coins they care about and receive real-time alerts the moment opportunities appear. With reliable delivery, flexible alert rules, and an intuitive interface, the platform helps traders stay informed, react faster, and never miss a critical price movement.
