lungfish-web3-starter - Build Web3 Faster - Layer0 (Free Tier)

The Lungfish Web3 Starter (Layer0 – Free Tier) is a clean, minimal, and production-ready backend starter designed for developers looking to build Web3 applications quickly and correctly. Built with Spring Boot 3.3.x, Java 17, and Web3j, this starter provides a solid foundation for any Ethereum-based backend, while also preparing your project for future multi-chain support (BTC, TRON, and more).
