Terra Classic Approaches Major SDK 53 Upgrade with April 17 Timeline
The Terra Classic network is preparing for a significant technical upgrade as the Software Upgrade to Version 4.0.0 with Cosmos SDK V.53 proposal has officially entered the voting stage.
The proposal outlines an upgrade to Cosmos SDK version 0.53.x, marking an important step in improving the network’s infrastructure and performance. This upgrade is expected to enhance overall efficiency and maintain compatibility with the broader Cosmos ecosystem.
The voting period for the proposal is scheduled to conclude on April 15, 2026. Community participation during this phase will determine whether the upgrade proceeds as planned.
If approved, the network will halt at block height 28,214,400. Based on current estimates, this halt is expected to occur on Friday, April 17, 2026, at approximately 14:30 UTC. However, the exact timing may vary depending on the chain’s block production speed as it approaches the specified height.
This upgrade represents another key milestone in Terra Classic’s ongoing development, as the community continues to focus on strengthening the network’s technical foundation.
