ArbiLayer is a free, no-sign-up for traders who work across exchanges. It shows live price spreads between CEXs and perp DEXs after trading fees, with a check that both exchanges list the same token contract. A funding scanner compares perpetual funding rates on Binance, Bybit, OKX, Bitget, Hyperliquid and more, normalised to 24h and APR. The listings tracker reads the full market list of 70+ exchanges every 15 minutes and flags coins the moment they start trading, with the contract address.
