Cross-Chain Concepts
Interoperability.
Why Cross-Chain Matters
The blockchain world is multi-chain: Ethereum, L2s, Solana, Cosmos, and more all coexist.
Cross-chain technology lets value and data move between these otherwise isolated networks.
Chains Are Isolated by Default
A smart contract on one chain cannot natively read or call a contract on another. Each chain is its own closed world.
Cross-chain protocols build the connective tissue that overcomes this isolation.
