Based

Based is a consumer crypto super app built on Hyperliquid that unifies trading, prediction markets, and real-world payments in a single self-custody account. Users trade spot and perpetual futures with sub-second execution and deep liquidity, speculate on prediction markets, and spend crypto from Solana, Arbitrum, and Polygon at 70+ million Visa merchants across 160+ countries via Based debit cards, including the premium Gold+ card. BasedCloud lets partners spin up white-label Hyperliquid trading frontends (web, mobile, desktop, Telegram), and a three-tiered affiliate program amplifies Hyperliquid referral fees. Based is backed by Pantera Capital, Coinbase Ventures, Hashed, Ethena, and Spartan Group. It publishes consumer product docs on GitBook and an agent-oriented llms.txt index, but exposes no public developer API of its own — programmatic trading runs on the underlying Hyperliquid API.

Based is profiled on the APIs.io network. Tagged areas include Company, Crypto, Cryptocurrency, Trading, and Payments.

Based’s developer surface includes documentation, support, engineering blog, pricing, and 6 more developer resources.
