23 Commits • 6 Features
Oct 1, 2025October 2025 focused on strengthening reliability, observability, and developer velocity for Sovereign-sdk. Key work spanned NOMT and Sequencer metrics and reliability improvements (including in-flight blobs limit, detailed NOMTStorageManager metrics, slot-number metrics, and pre-finalization sequencing flows, plus NOMT version bumps and metrics initialization relocation), NOMT commit metrics correctness fixes, dependency upgrades and configuration modernization (Celestia v6 upgrade, improved namespace handling via constants.toml and dev-branch rules), CI stability and test hygiene (dev-branch CI behavior, test cleanup and ZKVM patches, flaky-test tagging), NodeClient reliability improvements, and ongoing efforts in code modularization, autogenerated code flush, and logging optimization. Collectively these changes improved release reliability, observability, and developer velocity while delivering tangible business value with clearer metrics and faster iteration cycles.

Sep 1, 2025September 2025 (2025-09) monthly summary for Sovereign SDK. Focused on reliability, observability, and Celestia integration, delivering business value through improved metrics, safer data handling, and robust CI. Key features delivered include Celestia adapter metrics, Celestia upgrade to v5, and new TxPriority parameter, along with refactoring work to sov-soak-lib and test suite alignment for integration branches. Major enhancements to CI tooling and logging were accompanied by targeted timeouts and performance safeguards to prevent hangs. Major bugs fixed address API correctness, metrics reliability, and serialization safety, reducing risk in production and easing maintenance. The work demonstrates strong proficiency in Rust, OpenAPI, Celestia integration, metrics/telemetry, and CI automation, driving faster, safer releases.
