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.

Bridge and cross-chain infrastructure connects Hyperliquid to the broader crypto ecosystem, enabling asset transfers between chains. Across Protocol operates in this critical category that facilitates capital inflows from Ethereum, Arbitrum, and other networks. As Hyperliquid's DeFi ecosystem grows, efficient bridging infrastructure becomes essential for attracting liquidity and users from other chains.
