Understanding Cross Chain Messaging vs Bridging

Cross chain messaging like LayerZero's arbitrary calls differs from liquidity bridges by enabling data and function execution, not just assets. Omnichain protocols extend this to app level interactions across 70+ networks.

• Messaging: Sends payloads for dApps (e.g. ZRO funded calls).
• Bridging: Locks/mints tokens (e.g. Wormhole's <$0.01 flats).
• Hybrid: Stargate's 0.06% pools combine both.
• Security varies-oracles/relayers in LayerZero, light clients in IBC.

Factors in Choosing a ZRO Compatible Protocol

Evaluate chain count (LayerZero's 70+ tops most), fee structures (Synapse's 80% savings for volume), and models (CCIP's oracle consensus for enterprises). Security via dual proofs reduces exploits, while ULNs cut Ethereum costs.

• DeFi: Prioritize liquidity like Stargate.
• Devs: Configurability in Hyperlane or LayerZero.
• Users: Low fees in Wormhole under $0.01.
• Scale: IBC for sovereign, XCM for ecosystems.
