Arbitron is a non-custodial arbitrage terminal for crypto perpetual futures. It scans live order books across 19 exchanges — Binance, Bybit, OKX, Bitget, Gate.io, MEXC, KuCoin, HTX, Hyperliquid and more — and executes market-neutral trades: two hedged legs opened in parallel to capture the cross-exchange price gap and funding payments, without betting on direction. You connect trade-only API keys, so funds never leave your own exchange accounts and nothing can be withdrawn. Each user runs on a dedicated server with its own IP. Free public tools: live spread scanner, listing/delisting calendar,
