Stable is scheduled to activate mainnet version 1.9.0 at block height 45,091,000 on October 31, 2026. This infrastructure update aims to enhance network reliability and security for transaction processing and payment settlement systems.
Why it matters
The upgrade targets critical infrastructure used for high-frequency settlement, with the goal of increasing protocol resilience. By strengthening these core components, the update intends to minimize downtime in decentralized payment environments.
The 1.9.0 upgrade is hard-coded to trigger at block height 45,091,000. Operators using automated management tools must complete preparations 24 hours prior to the transition.
The players
Stable
A blockchain infrastructure provider focused on transaction processing and payment settlement protocols.
The details
The upgrade requires operators to replace node binaries, which are the software executable files that define network rules, once the system reaches the designated block height. Operators utilizing Stablevisor or Cosmovisor—automated tools for managing chain software transitions—must configure their environments 24 hours before activation. Nodes not using these managers must stop at the target height to facilitate a manual binary replacement process.
Timeline
October 30, 2026, 5 a.m. ET: Deadline for node operator preparations.
October 31, 2026, 5 a.m. ET: Activation of mainnet version 1.9.0.
The Tech Race
This release continues the iterative development trajectory of the Stable protocol. It marks a push to align infrastructure performance with the security requirements of high-volume payment settlement.
Service providers and node operators must manually replace binaries or update management tools before the October 31 activation. Users of the network should expect standard maintenance protocols to ensure continued settlement reliability during the transition.
The takeaway
The upgrade highlights the industry shift toward standardized, automated binary management for distributed networks. Observers should track the successful completion of block height 45,091,000 to gauge the network's stability post-deployment.
What happens next
Node operators must ensure preparations are finalized by 5 a.m. ET on October 30, 2026, to ensure compatibility with the version 1.9.0 activation.
