Across Protocol
Across Protocol is the leading intent-based cross-chain bridge, connecting over 15 chains — including Hyperliquid's HyperCore and HyperEVM — with near-instant settlement and some of the lowest fees in DeFi. Unlike traditional message-passing bridges, Across replaces step-by-step execution with user-declared outcomes called intents: users specify what they want, and a competitive network of relayers races to fulfill each transfer optimally. Backed by a three-layer architecture — a request-for-quote mechanism, a network of competitive relayers, and an on-chain settlement layer — Across guarantees fast fills averaging under one minute without sacrificing security or decentralization. Bridging 1 ETH costs under $1. The protocol has processed over $22B in cumulative volume across 15M+ transactions, making it one of the most proven interoperability solutions in production. For the Hyperliquid ecosystem, Across unlocks seamless capital inflows from Ethereum, Arbitrum, Base, Optimism, and beyond — giving users and protocols a reliable, low-cost on-ramp to both HyperCore's order-book liquidity and HyperEVM's growing DeFi landscape.

HyperIndex is a dedicated data infrastructure layer for the Hyperliquid blockchain, providing comprehensive indexing, querying, and API services tailored to the ecosystem's unique architecture. As Hyperliquid operates its own high-performance L1, developers and analysts face challenges accessing historical on-chain data, user activity, and protocol metrics in real time. HyperIndex solves this by maintaining indexed archives of Hyperliquid's order book events, trade history, liquidations, vault activity, and HyperEVM transactions — exposing this data through clean REST and WebSocket APIs. Whether you're building a portfolio tracker, analytics dashboard, trading bot, or DeFi protocol, HyperIndex provides the data backbone that makes it possible. The service supports complex queries — filtering trades by asset, user, or time window — without requiring developers to run their own archive nodes. By abstracting the complexity of raw blockchain data, HyperIndex accelerates ecosystem development and lowers the barrier to building on Hyperliquid. It functions as the ecosystem's equivalent of The Graph or Dune Analytics, purpose-built for Hyperliquid's specific data model and performance characteristics.

Ecosystem Integration
Across Protocol
Across Protocol operates on Multi-Layer (spans multiple hyperliquid layers). Spanning multiple layers lets it combine the strengths of each, though integration complexity is higher.
HyperIndex
HyperIndex operates on Multi-Layer (spans multiple hyperliquid layers). Spanning multiple layers lets it combine the strengths of each, though integration complexity is higher.
Both protocols share the same layer, maximizing composability potential.
