Across Protocol vs Purrswap

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.

Purrswap

Purrswap is a native DEX on HyperEVM, incubated by Abracadabra DAO and built on a licensed implementation of MIMswap's Proactive Market Maker (PMM) algorithm. Unlike traditional constant-product AMMs, PMM actively adjusts its price curve based on external reference prices, concentrating liquidity near the current market price and dramatically reducing slippage for both stablecoin and volatile-asset trading pairs. Purrswap inherits Abracadabra DAO's deep DeFi expertise — the team behind the MIM stablecoin and the original MIMswap protocol on Ethereum — bringing battle-tested, audited smart contract architecture to the Hyperliquid ecosystem. By deploying natively on HyperEVM, Purrswap benefits from Hyperliquid's high-throughput EVM execution environment, low transaction fees, and tight integration with the broader Hyperliquid DeFi stack including HyperCore's perpetual order book. The PMM model makes Purrswap particularly capital-efficient for stablecoin swaps and correlated-asset pairs where tight spreads and minimal impermanent loss are critical for LPs. As a community-aligned project incubated by one of DeFi's most recognized DAOs, Purrswap represents a meaningful bridge between the established Abracadabra ecosystem and Hyperliquid's rapidly growing on-chain economy.
