Across Protocol vs Zellic

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.

Zellic

Zellic is a rapidly growing blockchain security firm that combines deep smart contract expertise with strong cryptographic and systems security knowledge, serving protocols across EVM ecosystems including HyperEVM. Founded by top competitive CTF players, Zellic's team brings an attacker's mindset to every engagement, proactively identifying vulnerabilities in complex DeFi protocols, cross-chain bridges, and financial primitives. Zellic has audited hundreds of millions in TVL across lending protocols, DEXes, and infrastructure projects—many architecturally similar to what is being built on Hyperliquid. Their reports are known for clear vulnerability disclosure with actionable remediation guidance. For HyperEVM projects seeking an audit firm with fresh perspectives and a strong track record in cutting-edge DeFi security research, Zellic provides rigorous assessment that complements the traditional audit landscape and has earned a reputation as one of the most thorough firms for complex protocol reviews.
