# Solo is Moving to the Hiero Namespace

March 2, 2026

Michiel Mulders

Developer Relations

We’re continuing the transition of Hedera-related projects to **Hiero**, and today we’re announcing that [Solo](https://github.com/hiero-ledger/solo)
 is officially joining that journey.

As part of the broader ecosystem migration announced in 2024, projects are transitioning from the hashgraph namespace to vendor-neutral hiero-ledger namespaces under the Linux Foundation Decentralized Trust. This transition reinforces our commitment to open source, transparency, and community-driven governance.

### **What’s Changing?**

The **[Solo codebase](https://github.com/hiero-ledger/solo/)
 has already been migrated** to the hiero-ledger GitHub organization. However, there is **one remaining step** in this transition:

- The NPM package is **currently still published as**@hashgraph/solo
- It will be **moved to**@hiero-ledger/solo

### **Dual Publishing Timeline**

To ensure a smooth transition for developers, we will use a **dual publishing strategy**:

- **Dual publishing period**: **February 25th → end of July (6 months)**
- During this time, Solo will be published under **both namespaces**:
  - `@hashgraph/solo`
  - `@hiero-ledger/solo`

- After the dual publishing window, the package will be **published exclusively under**[@hiero-ledger/solo](https://www.npmjs.com/package/@hiero-ledger/solo)

The **exact version that marks the cutover** (when releases stop under @hashgraph/solo) will be communicated closer to the transition date, once it’s clear which release will serve as the final dual-published version.

### **What Should Developers Do?**

**In short: update the namespace to avoid any issues.**

- Start migrating your dependency to [@hiero-ledger/solo](https://www.npmjs.com/package/@hiero-ledger/solo) during the dual publishing period.
- Avoid waiting until the final cutover to prevent disruptions.
- Future updates and fixes will only be available under the new namespace after the transition is complete.
