# SDK Release Plan

**Helios plans to keep its developer stack lightweight—just a JavaScript/TypeScript package for dApps and automations, plus a Python wrapper for data work and scripting. Both point to the same on-chain ABI bundle, so upgrades happen once and flow everywhere.**

### SDK Packages

| Package     | What it’s for                               | Key upstream                                                                                                                                              |
| ----------- | ------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `helios.js` | Browser & Node apps, bots, simple scripts   | Built on **ethers.js v6.13.x** (compact, tree-shakable) ([Documentation - Ethers.js](https://docs.ethers.org/v6/getting-started/?utm_source=chatgpt.com)) |
| `helios-py` | Jupyter notebooks, back-end jobs, analytics | Wraps **web3.py 7.11 (Apr 29 2025)** async provider ([web3 - PyPI](https://pypi.org/project/web3/?utm_source=chatgpt.com))                                |

Each package auto-pulls ABI updates from the same registry; no separate indexing layer is planned.

### High-Level Roadmap

* **Q3 2025:** read-only queries, deposit/withdraw helpers.
* **Q4 2025:** borrow/repay and basic liquidation calls.
* **Early 2026:** optional cross-chain flash-ops helpers if demand justifies.

### Wallet Integration

One of the easiest way for wallet integration is relying on the open-source **`midl-js`** —drop a one-file connector PR there and every Satoshi-Kit app sees the new wallet next release.
