# Building Something Cool in Java + Crypto?

I’ve been working on a Java microservices project that enables crypto transactions across multiple chains — including Solana, Ethereum, and EVM-compatible Layer 2s.

The API is built with Spring Boot, designed for enterprise-grade scalability and modularity, so you can build anything on top that requires crypto transactions.

💡 What’s unique:

Solana integration without any dedicated Solana library — all cryptographic operations are implemented from scratch.

Cross-chain transfers supported.

SPL meme coin creation on Solana included.

Clean architecture and advanced cryptography at its core.

Would love to hear your thoughts — do you think this is valuable? Let’s discuss in the comments 👇
