Cross-chain & Bridges

Bridges and cross-chain protocols move assets and messages between otherwise isolated blockchains, and increasingly let applications operate across many chains at once. They are essential to a multi-chain world.

The category covers messaging layers (LayerZero, Axelar, Wormhole), liquidity bridges (Stargate, Synapse, Hop), and Bitcoin-native asset standards (Runes, Ordinals, Taproot Assets). Bridges have historically been a major target for exploits.
