- RCnet v3 has gone live as the final major test network prior to the Babylon mainnet upgrade. If a project runs on RCnet v3, it is guaranteed to run on Babylon.
- A new unit testing framework for Scrypto has been launched, enabling more streamlined and precise test creation.
In the Pipeline: What’s New?
For those who have been following the development of RCnet, the launch of version 3 (v3) brings an air of finality and maturity as it represents the last major testnet release before we shift gears to the Babylon mainnet upgrade. Though consumers may not notice a radical transformation when juxtaposed with RCnet v2, the focus has been keenly trained on stabilization and incremental enhancements.
RCnet v3 is now LIVE! 🌐
This is the last major test network release before the Babylon mainnet upgrade

Various tools have been updated for compatibility with RCnet v3, such as:
- Radix Wallet Preview & Connector Extension
- Radix dApp Toolkit
- Radix Engine Toolkit
- Gateway API
Tailored Testing for Scrypto Developers
Arguably, one of the most groundbreaking updates in RCnet v3 concerns Scrypto developers. A wholly new unit testing framework has been rolled out, which fundamentally alters the landscape for test creation. Developers no longer need to encapsulate an entire transaction within their tests; they can now write scenarios with a laser-focused scope and set precise pre- and post-conditions. For those interested in integration-level testing, the existing test runner framework remains operational.
In addition, types related to fixed precision math have been reworked to accommodate a broader range of real-world applications, thereby making the ecosystem more robust. This also allows the compiler to enforce stricter controls to preempt potential overflow scenarios.
A Few Noteworthy Clarifications
No Mainnet Tokens on RCnet v3: It’s crucial to remember that RCnet v3 is a test network, meaning assets created on it will not transition to the mainnet and will eventually disappear.
Future Test Releases: While there may be minor, under-the-hood updates to RCnet v3, don’t expect another major release before Babylon goes live.
Olympia to Babylon Migration: There are ongoing discussions about this, and as we near the switch, more detailed articles will emerge.
Stokenet Test Network for Babylon: Yes, a Babylon Stokenet will be initiated around the Babylon mainnet’s go-live time, starting afresh without any state from the Olympia-based Stokenet.
Radix has gone to great lengths to make RCnet v3 not just an iteration, but a robust platform for developers to test and hone their projects before the much-anticipated Babylon upgrade. So, let the testing begin!
