The record

Intended users: The maker says the product was built for DeFi traders, including people using liquidity pools, bonding curves, prediction markets, and perpetual futures.
Supported chains: The homepage lists Bitcoin, Solana, Ethereum, TRON, Base, BNB Chain, Polygon, and Arbitrum as supported chains.
Exchange imports: The homepage lists Binance, Coinbase, Kraken, Bybit, OKX, Hyperliquid, MEXC, Orderly, CoinSpot, and generic CSV as exchange imports.
DeFi and trading features: The homepage describes automatic tracking for Hyperliquid perpetuals, prediction markets, launch platforms, liquidity pool yields, Jupiter DCA and perpetual positions, bridges, and NFTs.
