Across Protocol vs Passivbot

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.

Passivbot is a popular open-source cryptocurrency trading bot with native Hyperliquid support, implementing recursive grid-trading and DCA (dollar-cost averaging) strategies for perpetual futures markets. Written in Python with a strong community following, Passivbot allows traders to run fully automated grid strategies on Hyperliquid's perp markets without relying on centralized exchange APIs. The bot continuously places limit orders in a dynamic grid around the current price, capturing bid-ask spreads and mean-reversion moves. Passivbot includes an advanced backtesting engine and optimization framework that uses evolutionary algorithms to tune strategy parameters across historical data. With active maintenance, extensive documentation, and a dedicated Discord community, Passivbot has become one of the most trusted open-source tools for automated Hyperliquid trading. Its transparent, auditable codebase makes it particularly appealing to traders who are wary of closed-source bot solutions.
