About Perpia
Perpia is a funding-rate arbitrage scanner. It compares perpetual funding across 25 DEX and 8 CEX in real time and surfaces delta-neutral opportunities — long the venue paying the most negative funding, short the one paying the most positive — with the costs and limits shown up front. It also runs spot-perp cash-and-carry, pairing those perps with 8 spot venues to collect positive funding while holding the spot leg.
What it does
The scanner reads live funding rates, order books, volume and open interest, annualizes every venue's rate onto one scale, and ranks the resulting spreads by net APR — after fees, bid/ask spread and estimated slippage. Alongside that it tracks how long each spread has persisted, the real max size a book can absorb, and a 30-day realized backtest of the current pair. There are free Telegram alerts, a payback calculator, and a dedicated view for xStocks (tokenized equities) funding.
Why it exists
Most funding screens show the gross rate — the biggest possible number. That number is usually a mirage: a 1000% APR on a book that caps at a few thousand dollars, or a rate that flips within hours. Perpia is built around the opposite instinct — show what you could actually keep after costs, how much size the market supports, and whether the spread has held. The goal is to help you filter, not to chase the top of a list.
Who builds it
Perpia is built and run by an independent developer who trades funding arbitrage. It is not backed by any exchange, and it does not take deposits or custody funds — it is an analytics tool that points at where opportunities are, with the caveats attached. Every calculation is documented on the methodology page.
