Jul 1, 2026July 2026 Monthly Summary (Sovereign SDK) – Sovereign-Labs/sovereign-sdk Overview: Focused on reliability, performance visibility, and build efficiency for the Celestia integration and DA layer experiments. Delivered robust failover capabilities, reduced build times through feature-driven compilation, and established a benchmarking framework to evaluate data availability paths. Key features delivered: - Celestia Adapter Failover and Fallback Endpoints: Added support for secondary RPC/gRPC endpoints with health checks and switch-back logic. Configurable via environment variables to enable seamless failover and recovery. Integrated comprehensive tests using Toxiproxy to validate failover/recovery scenarios. Commit: ae46dde0439e9fc202e2a9791a30497de53fd062. - Cargo Features for DA Layer and zkVM Selection: Refactored demo-rollup to expose two cargo features (mock_da and celestia_da) to optimize compilation times by excluding unnecessary zkVM guest builds; compile-time selection of the DA layer with runtime flexibility for zkVM in mock_da; updated CI workflows, Makefiles, and documentation. Commit: b7a4a46acd8cfff5aead2b800b91884203d06f85. - Compression Benchmarking Infrastructure for SP1: Established infrastructure for benchmarking Celestia SP1 compression performance, including generation of test fixtures and utilities to save/load rollup block data to compare uncompressed vs. LZ4-compressed payloads; enables performance analysis of data availability submission paths. Commit: ca269287125014d42d8dcfc1fbe989f42c3e6542. Major bugs fixed: - No critical defects reported this month. Reliability improvements were delivered via automated failover testing and robust configuration options, reducing potential downtime during endpoint outages. Overall impact and accomplishments: - Improved system resilience and operational visibility with automatic failover capabilities and environment-driven configuration. - Increased developer efficiency by introducing feature-based build configurations that reduce compile times and streamline CI processes. - Established a measurable performance analysis footing for data availability paths, enabling data-driven optimizations. Technologies/skills demonstrated: - Rust feature flags, environment variable configuration, and robust integration testing (Toxiproxy). - CI/CD improvements (Makefiles, workflows) and documentation updates. - Benchmarking infrastructure development and data handling utilities for SP1 compression analysis. Business value: - Reduced risk of service disruption through seamless endpoint failover. - Faster development cycles and shorter PR feedback loops due to smaller, targeted builds. - Ability to quantify compression and data availability performance, informing optimization priorities for production workloads.

Jun 1, 2026June 2026: Consolidated reliability, performance, and API quality improvements across Sovereign SDK with notable business-value outcomes and robust technical execution. Key features delivered include improved user-facing error handling for HTTP 503, base image optimization with risc0 recursion baked in, async logging to boost throughput and reliability, and targeted API/data-model refinements. In addition, the Rollup height concept was renamed to slot_number with a new websocket subscription and associated API/docs cleanup, expanding client interoperability and reducing confusion. Celestia integration received multiple enhancements (compression support, total_len authentication, and config hardening) along with re-enabled block verification for end-to-end correctness. Build and CI improvements reduced pipeline churn, while pruning, SP1 guest build optimizations, and caching improved developer velocity. Finally, native EVM performance benefited from enabling revm/secp256k for faster transaction processing. These changes collectively reduce risk, accelerate delivery, and improve data integrity across the platform.
