Terra Classic Approaches Major SDK 53 Upgrade
The Terra Classic network is preparing for a significant software upgrade to version 4.0.0, based on Cosmos SDK v0.53.x. The upgrade is scheduled to take place on April 17, 2026 at approximately 22:08:10 GMT+7.
With only four days remaining, the community is entering the final phase of preparation for one of the most important technical updates in recent months.
Upgrade Timing and Network Details
The upgrade will occur at a specific block height, ensuring a coordinated transition across the network. At the time of announcement, more than fifty thousand blocks remain before the upgrade is activated.
This block based scheduling allows validators, developers, and infrastructure providers to align their systems in advance and reduce the risk of disruption.
What the Upgrade Includes
Version 4.0.0 introduces integration with Cosmos SDK v0.53.x, which brings improvements to performance, security, and overall network efficiency.
This update is part of Terra Classic’s ongoing effort to modernize its infrastructure and remain aligned with the broader Cosmos ecosystem.
Why This Upgrade Matters
The SDK 53 upgrade is an important step in strengthening the foundation of the Terra Classic network. It supports continued development, improves reliability, and helps ensure long term sustainability.
For validators and node operators, updating software before the scheduled block height is essential to remain in sync with the network.
Final Preparations Underway
As the countdown continues, the Terra Classic community is focused on ensuring a smooth transition. With the upgrade date approaching, all participants are encouraged to complete necessary updates and monitor network progress closely.
The next few days will be critical as Terra Classic moves toward this major milestone.
