Live fee intelligence for crypto swaps

Quantora — the framework that finds the cheapest route across exchanges.

Stop losing money to invisible fees. Quantora scans centralized and decentralized exchanges, network fees and hidden costs to route every swap where you keep the maximum possible amount of crypto.

Fees are the hidden tax on every crypto swap.

On paper, many exchanges look similar: same pair, similar rate. In reality, every swap is a combination of:

Service fees charged by exchanges;
Network / gas fees that constantly change;
Minimum and maximum limits per pair;
And extra “convenience” fees hidden in the final quote.

You can manually check 2–3 venues. Quantora checks 10's of them in seconds and routes your users where they keep more of what they swap.

Quantora in one line

Quantora is a framework that sits between your users and the exchanges, constantly calculating:

Best resulting amount after all fees;
Alternative routes with slightly higher fees but lower slippage;
Custom rules per region / compliance / preferred venues.

You integrate one framework. Your users get a smarter swap button everywhere.

How Quantora works

UNDER THE HOOD

Aggregate live quotes

Quantora pulls rates, fee schedules and gas cost from centralized and decentralized exchanges, aggregators and custom venues you configure.

Simulate net output

For each possible route, Quantora simulates the swap, subtracts all direct + indirect fees and calculates the exact amount the user ends up with.

Route & explain

Quantora returns the best venue plus human-readable breakdown of fees so you can display transparent routing to users or keep it fully invisible in the backend.

Framework modules

PLUG ONLY WHAT YOU NEED

Q-Scanner

Normalizes data from exchanges, DEXes and aggregators. Tracks fee tiers, maker / taker fees, gas costs, limits and temporary promos in one unified format.

Input: venues & pairs · Output: clean fee-aware quotes.

Q-Router

Computes optimal routes based on net received amount, latency, reliability and your own routing rules.

Supports custom weighting (slippage, liquidity depth, regions...).

Q-Policy

Enforces your constraints: blocklist venues, prefer regulated ones, limit per-venue exposure and apply jurisdiction-based rules.

Keeps the routing smart but compliant with your stack.

Q-Metrics

Time-series analytics of how much your users saved in fees, where routes were sent and which venues underperform.

Perfect for dashboards and investor updates.

Q-SDK

Lightweight SDKs for bots, web frontends and services. Bring live routing into a Telegram bot or a single “Best price” button on your site in minutes.

REST, WebSocket and simple client libraries.

Q-Sandbox

Simulation environment to test strategies on historical fee + price data without touching real liquidity.

Great for quant teams and research.

This demo shows exactly how Quantora sits behind your interface: your user chooses what to swap, and the framework does the heavy lifting in the background.

• You can fully customize which venues are included.
• You decide how to weigh fees vs. latency vs. reliability.
• You keep full control over UX — Quantora only returns data.

The same logic can power:

— A single “Best price” button on your website
— A command in your trading / Telegram / Discord bot
— A background optimization layer inside your existing product

Who Quantora is built for

USE CASES

Trading bots

Plug Quantora into your existing trading bot to always route through the venue that leaves the most crypto after all fees are paid.

Wallets & Super-apps

Add a “Best route” toggle to your swap screen. Quantora becomes the invisible engine that optimizes routing behind a familiar UI.

Quant / research teams

Use the historical fee & route data to design strategies, measure real cost of trading, and justify venue selection with hard numbers.

High-level architecture

BIG PICTURE

Quantora was designed as a framework, not just a single API endpoint. You can embed its components into your own infrastructure or run it fully managed.

• Data layer: connectors to CEX / DEX / aggregators.
• Computation layer: the routing and simulation engine.
• Policy layer: rules per region / venue / user group.
• Interface layer: SDKs, REST, Websocket, CLI.

FLOW User → Quantora → Venue

Your UI / Bot → Quantora API

↓ Q-Scanner: queries venues ↓ Q-Router: simulates net received ↓ Q-Policy: applies your constraints

← Best route + breakdown

From the user’s perspective, it’s still “just a swap”. From your perspective, every swap is now optimized.

Developer-first by design

DOCS

Quick start

Make a single HTTP request to get a list of routes sorted by net amount received.

POST /v1/routes
{
  "from_token": "USDT",
  "to_token": "BTC",
  "amount": 1000,
  "network": "ethereum"
}

Response example

[
  {
    "venue": "Dex A",
    "rate": 0.0000231,
    "service_fee_pct": 0.20,
    "network_fee": 3.10,
    "you_receive": 0.02301,
    "is_best": true
  },
  ...
]

Attach this directly to your UI, or process / log routes for analytics.

Roadmap

WHAT’S NEXT

Phase 1 · Core routing

Multi-venue routing, fee-aware simulation, SDK for bots and web frontends.

Phase 2 · Advanced policy & analytics

Fine-grained policies, historical data lake, dashboards, custom optimization profiles.

Phase 3 · Cross-chain & predictive layer

Cross-chain routing with bridge fees + predictive models for fee spikes and congestion.

FAQ

QUESTIONS

Is Quantora a DEX aggregator?

Partially. Quantora can aggregate DEXes, but it is designed as a general framework that also works with CEX APIs, P2P desks and your internal routing logic.

Can I hide which venue was chosen?

Yes. You control what is shown to your users. Quantora only returns data. You decide whether to display full breakdown or keep routing fully internal.

Which languages / stacks are supported?

Any stack that can speak HTTP/WebSocket can use the core API. On top of that, we provide small SDKs that can be used directly in bots or web frontends.

Every swap your users make can be cheaper.

Quantora is the missing layer between “click swap” and “best possible route”. Start with a single integration and measure how much you save on real volume.
