Hyperlane is a secure cross-chain communication protocol that allows Decentralized Applications (DApps) to safely communicate and move assets between any blockchain. It is often referred to as the "Composability Layer," as it connects disparate blockchain ecosystems.

The crypto world consists of many isolated blockchains (Ethereum, Solana, Polygon, Cosmos, etc.) that cannot "talk" to one another. Traditional "Bridges" often require trust and are vulnerable targets for hackers.

Hyperlane offers a trustless way for these systems to interact, allowing DApps to function as a unified whole, even if they are deployed on different networks.

• Permissionless: Unlike other interoperability protocols that only work with a limited set of networks, Hyperlane can be deployed on any blockchain (be it L1, L2, or even a custom rollup) without needing permission from the Hyperlane team. This makes it universally adaptable.

• Security: The protocol uses a modular security system, allowing each DApp or network to choose its own security mechanisms (e.g., using ZK-proofs or multisig oracles) to verify cross-chain messages.

For DeFi platforms like DEXes (Decentralized Exchanges) and lending protocols, Hyperlane enables:

• Universal Liquidity: Aggregating liquidity from different blockchains into a single pool.

• Remote Function Calls: Allows a smart contract on one chain to remotely call a function of a smart contract on another chain.

Essentially, Hyperlane aims to become the foundational messaging layer, making the differences between blockchains seamless and invisible to the end-user.
