Nov 1, 2025

November 2025 highlights for CKS-Systems/manifest: Implemented core ordering improvements and risk controls with ReverseTight ordertype, enhanced fill-tracking support by adding JUP aggregator 3 and phantom to originating protocol tracking, and introduced batch global gas prepayment to reduce per-transaction friction and improve cost predictability. Strengthened data integrity and observability through enhanced phantom detection in the fill feed and a block feed overhaul that adds blocktime to fills, switches to GetBlock-based fill feeds, and removes the legacy block feed. Additional capabilities delivered include notional and checkpoints endpoints, a global seat fee, and savings of checkpoint timestamps. Reliability and performance improvements were complemented by a series of stats-server refinements (cleanup/refactor, added quotes support, and improved websocket/mutex handling) along with code hygiene and publishing workflow changes. Each of these enhancements contributed to better ordering fidelity, cost transparency, risk visibility, and operational efficiency across the trading workflow.

Sep 1, 2025

In September 2025, delivered a new lazy signer verification feature for manifest swap paths, implementing on-demand signer checks and gas-fee refinement to improve efficiency and accuracy during market expansions. The feature defers signer validation until necessary, supports reversible orders, and ensures the payer avoids gas charges when market expansion is not required. This reduces unnecessary gas spend and prepares the system for scalable growth.

In November 2024, CKS-Systems/manifest delivered end-to-end improvements across data integrity, market visibility, and system resilience. Key features include enhanced fills processing with sorting by descending and a timestamp, plus dedup filtering to improve traceability and feed reliability. Holdings integrity validation ensures in_atoms are backed by actual funds, reducing risk of fund mismatches. Market UI enhancements include sorting by volume, a toggle to show all markets, top-5 best orders display, and live orderbook updates in debug UI, strengthening trader decision support and UI stability. Volume and metrics data pipelines were expanded with a Coingecko stats server, Defillama volume endpoint, and a volume metric with a mint dimension, alongside websocket resets for the manifest stats server to improve reliability. The team also focused on quality and reliability through code cleanup, increased test coverage, CI improvements (Rust checks on PRs, Certora audits, and related tooling), and improvements to stats server stability (graceful websocket handling, connection expiry, and automatic reconnection). These efforts collectively enhance data accuracy, operational resilience, and business value while accelerating future feature delivery.
