lebroker lists every long/short pair across perpetual-futures venues and ranks it by the funding it earns: long the asset where funding is low, short it where funding is high, and collect the gap while the two positions cancel each other’s price risk. Most tools stop at the gross rate. lebroker also prices the trade at your size: the fees, the cost of crossing both order books at entry and at exit, and what is left once that cost is spread over the time you hold the pair. It comes in two parts:
  • The public site and its API list the opportunities and quote a pair. They read public market data only.
  • The app runs your strategies: it opens both legs, follows your rules, keeps your margin level and tells you what happens. You sign in with your wallet; lebroker runs it for you.

Venues

Hyperliquid, Aster, Polymarket Perps, Lighter and Extended today. An executor trades on the first four, Lighter once you set it up; Extended is listed and ranked, not traded yet. Each venue is read through one adapter that turns its funding, fees and order book into the same shape, so a pair can mix any two of them. Each venue decides who may use it. Checking it is your responsibility.

What lebroker never does

lebroker never holds your funds, and never moves them out of your wallet’s own accounts without your signature: on each venue, the access you give it trades only. You decide what it trades.
