Butter Network is an omnichain interoperability hub that utilizes ZK-refactored light clients. Light clients are simplified nodes that use minimal data to validate transactions through cryptographic hashes and Merkle proofs. The integration of Zero-Knowledge Proofs (ZKPs) allows for the verification of statements without revealing underlying information. The Butter Omnichain Service facilitates cross-chain synchronization and contract calls. Key functions include transferOut for sending data to a destination chain and transferIn for verifying and delivering data using a receipt from the source chain. The platform supports various omnichain development use cases, including Omnichain Swap for low-fee coin swapping, Omnichain GameFi for play-to-earn gaming, and Cross-chain Lending, which allows users to collateralize on one chain and borrow on another.
