SDK Release Plan

*subject to change without notice

PreviousFlashloanNextSmart Contract Interface via MIDL (EVM on Bitcoin)

Last updated 28 days ago

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) ()

helios-py

Jupyter notebooks, back-end jobs, analytics

Wraps web3.py 7.11 (Apr 29 2025) async provider ()

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. ()
