Basic Introduction:
Layer is an Ethereum scaling solution that leverages Web Assembly, which allows developers to write applications in languages like Rust that can run anywhere - even on an iPhone. Layer's product "Layer SDK" allows developers to build new layers on Ethereum that run full-stack blockchain-based applications, including smart contracts, consensus mechanisms, UIs, and verifiable off-chain services (AI agents, ZK provers, serverless functions, decentralized messaging servers, etc.).
