Overview
Cross-chain is technology enabling assets and messages to move between different blockchain networks. It addresses the fragmentation of the multi-chain ecosystem. Bridges and messaging protocols enable it.
How It Works
Cross-chain systems lock assets on one chain and issue representations on another, or relay messages between chains. Trust models vary from federated to decentralized. Security is a central concern.
Why It Matters
Cross-chain interoperability unlocks liquidity and users across the ecosystem. It is essential for a connected Web3. Its security risks require careful design.
