Cross-Chain Bridges: Connecting the Multichain Economy

Why Bridges?

As new blockchains and rollups multiply, cross-chain bridges allow seamless movement of assets and data. Leading bridges—Wormhole, LayerZero, and Axelar—facilitate billions in liquidity each day, letting users trade and lend across ecosystems.

Risks & Defenses

Bridge hacks have been the largest source of DeFi losses in past years. Innovations now focus on enhanced security: multi-sig signers, light-client verification, and incentive-aligned economic guarantees. Some bridges use insurance vaults or bonding mechanisms to cover potential exploits.

Composability & Future

With interoperability a core user demand, bridges are moving toward fully modular, permissionless frameworks—paving the way for an Internet of Blockchains where liquidity and protocols operate above chain-level silos.
