Across Protocol vs go-hyperliquid

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.

go-hyperliquid is a community-developed Golang SDK for the Hyperliquid API, providing idiomatic Go bindings for trading, market data, and account management on Hyperliquid. Built with Go's concurrency model in mind, the SDK leverages goroutines and channels for efficient WebSocket streaming and concurrent order management—making it well-suited for high-throughput trading systems written in Go. The library covers the full Hyperliquid API including REST endpoints for order placement, account queries, and historical data, as well as WebSocket subscriptions for real-time order book updates and trade feeds. With typed request and response structures, comprehensive error handling, and context-aware API calls, go-hyperliquid provides the idiomatic Go developer experience that the Hyperliquid ecosystem previously lacked, enabling the large Go trading infrastructure community to build on Hyperliquid. The SDK has active contributors and is maintained alongside the official Python and Rust SDKs.
