The wait is over — the dYdX Chain public testnet is now live, marking a major leap forward in the evolution of decentralized exchange infrastructure. With the successful completion of v4 Milestone 4, we’re unlocking broader access to a robust, community-driven testing environment designed to refine the future of open finance.
This milestone arrives ahead of schedule, reflecting the team’s commitment to rapid iteration and transparent development. The public testnet officially launched on July 5, 2023, at 17:00 UTC, opening the doors for developers, validators, traders, and enthusiasts to engage with core functionalities in a real-world setting.

Recap: What Was Achieved in Milestone 3?
Before diving into the new capabilities, it’s important to recognize the foundation laid during Milestone 3. This phase focused on internal stabilization and feature enhancement within a closed test environment. Key upgrades included:
- Implementation of limit order execution
- Introduction of dynamic funding rates for improved market equilibrium
- Migration to ABCI 2.0 and integration of the latest Cosmos SDK features
- Comprehensive documentation tailored for validators and market makers
During this stage, a select group of external validators participated in the private testnet. Their involvement allowed the team to stress-test critical network operations such as genesis setup, node synchronization, software upgrades, and end-to-end trading workflows. These efforts ensured that the system could scale securely before public exposure.
Milestone 4: Powering Up for Public Testing
Milestone 4 represents the culmination of essential features required for a functional, scalable public testnet. Its early completion underscores the project’s momentum and technical readiness.
The public testnet launches with support for Bitcoin and Ethereum markets, offering users immediate exposure to high-demand assets. However, the open-source nature of the protocol means that additional markets — expected to exceed 30+ — will be introduced through future network upgrades.
With over 40 validators already participating or preparing to join, the network reflects a truly decentralized validator set, reinforcing resilience and trustlessness.
