Sep 1, 2025September 2025 highlights for pyth-crosschain: Delivered two major features that enhance efficiency, correctness, and scalability: cross-feed and cross-transaction deduplication, and batched updates via PushUpdates. Implemented TTL-based deduplication for transaction updates and refactored feed deduplication to retain only the latest distinct update per feed across multiple feeds. Added PushUpdates JSON-RPC support and updated protocol/SDK dependencies, enabling the agent to process batched updates. These changes reduce duplicate processing, lower network overhead, and improve throughput across cross-chain feeds.

Aug 1, 2025Month: 2025-08 — Performance-review-friendly summary of cross-chain initiatives in pyth-crosschain. Delivered two major features with strong business value and robust quality improvements. Key features delivered: - Pyth Hermes Rust client: real-time price feed with robust connectivity (automatic retries, message deduplication, configurable endpoints, timeouts, and backoff strategies). Branding renamed to pyth-hermes-client-rust; established CI/CD workflows and dependency updates. - Pyth Lazor protocol robustness improvements: version alignment across crates, Price/Rate refactor for improved robustness, and added tests for decimal multiplication to ensure accuracy across precisions. Major fixes: - Maintenance fix: rename Hermes Rust client to pyth-hermes-client-rust (addressing branding/consistency across codebase and docs). Overall impact and accomplishments: - Significantly improved reliability and timeliness of cross-chain price feeds, reducing data latency and connection churn in real-world usage. - Strengthened protocol correctness and test coverage, reducing risk of pricing inaccuracies across different precisions. - Streamlined deployment with updated CI/CD pipelines and dependency management, enabling smoother future iterations. Technologies/skills demonstrated: - Rust, real-time streaming, fault-tolerant connectivity (auto-retries, dedup), and backoff strategies. - Cross-chain architecture and protocol robustness (Lazor), plus version alignment across crates. - CI/CD workflows, dependency updates, and test-driven validation (decimal multiplication tests).
