Hyperlane is a permissionless interoperability protocol for cross-chain communication across different blockchain environments. It enables message passing and asset transfers across different chains without relying on centralized intermediaries or requiring any permissions. Anyone can deploy hyperlane, whether it is a layer 1, rollup, or app-chain, and start building cross-chain applications right away—no approvals, no intermediaries. Hyperlane's Interchain Security Modules (ISM) allow developers to configure, compose, and customize their security model according to their application's needs. Hyperlane enables cross-chain communication for multiple virtual machines (VMs), including EVM, SVM and CosmWasm. It also supports cross-VM interactions, such as EVM ↔ SVM asset transfers.
