DEX Funding Rate Aggregator

The first Actor on Apify Store dedicated to DEX perpetual funding rates.
Aggregate live funding rates across Hyperliquid, Aster, Lighter, and Pacifica — with Binance and Bybit as CEX benchmarks — in a single call. No API key required.

The Problem

DEX perpetual funding rates are scattered across 4+ different chains and APIs with no unified view. A trader trying to find carry-trade opportunities must manually check Hyperliquid (Ethereum L1), Aster (BNB Chain), Lighter (Ethereum ZK L2), and Pacifica (Solana) — all with different data formats and funding intervals.

Meanwhile, DEX funding rates routinely diverge from CEX (Binance/Bybit) by 10–20% APR — a real, recurring arbitrage opportunity that goes undetected without cross-venue aggregation.

The Solution

This Actor fetches, normalizes, and compares funding rates across 6 venues in one call, surfacing:

• 🏆 Best carry-trade pair: which venue to long, which to short
• 📊 Cross-venue spread: total APR captured by holding both sides
• 📡 DEX-vs-CEX spread: how much DEX funding deviates from CEX baseline

Live example output (real data, June 20 2026):

Symbol	Best Long	Best Short	Spread APR
ETH	Pacifica (−9.6%)	Hyperliquid (+11.0%)	20.5%
SOL	Binance (−7.2%)	Hyperliquid (+11.0%)	18.1%
BTC	Pacifica (−7.3%)	Hyperliquid (+8.3%)	15.6%

A 20% APR spread on ETH means: long ETH on Pacifica (receive 9.6% APR from shorts), short ETH on Hyperliquid (receive 11.0% APR from longs) = 20.6% annualized yield, delta-neutral.

What It Does

1. Fetches live funding rates from 6 venues in parallel
2. Normalizes all rates to APR% (accounts for different settlement intervals: 1h vs 8h)
3. Computes cross-venue spread, DEX-vs-CEX spread, best long/short venue per symbol
4. Filters & sorts by spread size or absolute funding magnitude
5. Alerts via Telegram when funding exceeds your threshold

Why This Matters

Carry trading is one of the most consistent yield strategies in crypto — but it requires knowing where the rate imbalance is. CEX funding rates are well-covered. DEX rates are not.

This Actor fills that gap: one call, 6 venues, actionable spread signal.

Use cases:

• Quant traders — scan for entry signals, run on schedule via Apify
• DeFi protocols — monitor funding conditions across chains
• Risk desks — track DEX-vs-CEX divergence as a market stress indicator
