What is smart contract interoperability?

It’s the ability of smart contracts to communicate, exchange data, and execute transactions across different blockchain networks, breaking the isolation of individual chains.

What is a blockchain bridge?

A blockchain bridge is infrastructure that securely connects separate blockchain networks, enabling data and value transfer between them without centralized intermediaries.

What is the bridge trilemma?

It’s the challenge of simultaneously achieving high security, low latency, and broad extensibility in cross-chain protocols - balancing all three at once remains extremely difficult.

What are the key benefits of interoperability?

Benefits include unified liquidity, free asset portability, simplified development, enhanced blockchain competition, and better developer experience through standardized cross-chain protocols.

What real-world applications use smart contract interoperability?

Applications include cross-chain DeFi, multi-chain lending, tokenized asset transfers, cross-chain stablecoins, and decentralized exchanges accessing liquidity from multiple blockchains.
