Abstract

Harmonic Laboratories (HLabs for short) is an R&D firm born and focused solely on the Cardano ecosystem.

Harmonic Laboratories supports and maintains a considerable portion of the TypeScript tooling for the Cardano ecosystem, which the majority of Cardano developers use, either directly, or indirectly via other libraries that depend on code written and maintained by HLabs.

The mission of HLabs is for true decentralization to become the baseline of application development, not only a nice-to-have feature.

### Duration & Milestones

This proposal spans over **12 months**, throughout which there will be several deliveries and demos. Amongst the key deliveries, we note:

- maintenance for an upcoming hard fork; - a production-ready light node ([Gerolamo](https://github.com/HarmonicLabs/gerolamo)); - a production-ready, imperative and efficient, programming language for smart contracts ([pebble](https://github.com/HarmonicLabs/pebble)).

### Total Budget Ask

The estimated USD budget is of **`$2,250,000`** (or **`₳6,428,571`**) + 25% in refundable contingency (**`₳1,607,143`**); for a total ask of **`8,035,714 ADA`**.
