Blockchain interoperability

Blockchain interoperability is the ability of different blockchain networks to communicate, share data, or transfer assets between each other. Without interoperability, assets and applications can be locked inside separate ecosystems. Interoperability can involve bridges, messaging protocols, wrapped assets, or shared standards. Moving activity or assets across networks can change fees, speed, security assumptions, transaction finality, and how users access blockchain applications.

For example, if a user holds USDC on Ethereum but wants to use a Solana-based app that accepts USDC on Solana. They can use a cross-chain bridge to move USDC from Ethereum to Solana.
