Name: Introducing Hypernate: Data Mapper Framework for Hyperledger Fabric Chaincode

Meet Hypernate: a fresh, open-source way to write JVM Fabric chaincode with less key-value boilerplate and more joy — think entities + CRUD, declarative/composite keys, safe range queries via value mappers, and a plug-and-play middleware pipeline for logging, tracing, and caching.

**Repos**

* [LF-Decentralized-Trust-labs/hypernate](https://github.com/LF-Decentralized-Trust-labs/hypernate)
* [LF-Decentralized-Trust-labs/hypernate-samples](https://github.com/LF-Decentralized-Trust-labs/hypernate-samples)

**Planned agenda**

* Greetings & why we built Hypernate
* Feature tour: entities, keys, mappers, middleware
* Live coding: refactor a basic Fabric contract with Hypernate
* Run the samples & pro tips
* Roadmap & contributor Q&A

**What you’ll learn**

* How to model entities and do clean CRUD without fuss
* Smart key design (primary/composite, numeric pitfalls, value mappers)
* Drop-in middleware (logging, tracing, write-back caching)
* Using HypernateContract, HypernateContext, and Registry
* Running the samples locally — and how to jump in with issues/PRs

**Who should attend**
Fabric devs, architects, educators, and everyone interested in smart contracts :)
