Not every cryptocurrency application needs access to your exchange account.
When people think about crypto platforms, they often assume the first step is connecting an exchange account through an API key.
That assumption makes sense for trading bots, portfolio managers, and automated execution systems. These applications need authenticated access because they interact directly with user accounts.
But what if your application is designed only to help users research the market?
That question became one of the design principles behind Exarbi.
Separating Research From Trading
Our goal was simple:
Help users compare cryptocurrency prices across multiple global exchanges without asking them to connect exchange accounts.
Instead of becoming another trading platform, we wanted to build a research tool.
This decision influenced almost every architectural choice we made.
Why We Chose Not to Require APIs
Requiring exchange API keys introduces additional complexity for users.
Typical onboarding often includes:
- Creating API credentials
- Choosing permissions
- Understanding security settings
- Managing API restrictions
- Updating or rotating credentials
For users who only want to compare markets, those steps create unnecessary friction.
Removing account integration makes getting started much simpler.
User Control Comes First
One design principle we strongly believe in is keeping users in control.
Market research and trade execution don't have to happen inside the same application.
Users can analyze opportunities, compare exchange prices, and then decide for themselves where and when to trade.
The platform provides information.
The trading decision always belongs to the user.
Engineering Challenges
Building a comparison platform still presents technical challenges.
Some of the areas we continuously work on include:
- Aggregating market data from multiple exchanges
- Normalizing trading pairs
- Handling symbol differences between exchanges
- Maintaining reliable data updates
- Presenting information with low latency
These problems are interesting because every exchange exposes market data differently.
Looking Ahead
As cryptocurrency markets continue to evolve, we believe research tools should remain simple, transparent, and easy to use.
Automation has its place, but not every user is looking for a trading bot.
Sometimes all you need is accurate market information presented clearly.
That's the philosophy behind Exarbi.
