LINE PROTOCOL is a blockchain infrastructure with a modular architecture that provides developers with an SDK for quickly creating Web3 and GameFi applications. The SDK includes ready-made modules, built-in wallet support, compatibility with multiple blockchains, plugins for Unity and Unreal Engine, functions for NFT integration, smart contract templates, and tools for DAO and governance.

The platform is designed to simplify dApp and game development: it speeds up application launch thanks to a ready-made stack, reduces the complexity of integrating blockchain functions, and allows cross-chain connections to interact with networks such as Ethereum and Solana. 

The project is in active development, so some of the announced features may not yet be implemented or may be available in a limited form.
