Feb 1, 2026February 2026 monthly summary for chainflip-backend focused on delivering robust liquidity analytics, expanding asset coverage, and strengthening test infrastructure while fixing critical production issues. Key features delivered: - Liquidity Provider EMA Statistics Enhancements: Implemented AggStats as a single storage item (BTreeMap) with higher-precision metrics via FixedU128, added weight calculation for update_agg_stats, and introduced purge_balances governance operation. Refined the EMA data lifecycle with pruning of old entries when magnitude falls below a threshold (10$). Updated test coverage to align with fixed-precision semantics and renamed/streamlined sampling interval to 1 day. - Support for New Assets: Wbtc, ArbUsdt, SolUsdt: Added asset interfaces, updated deployed addresses, enhanced deposit monitor integration, and extended broker/tests to cover the new assets. - Testing Framework Enhancement: Vault Swap Tests migrated to Chainflip IO to improve test organization, readability, and reliability across broker accounts. - Production stability improvement: Fixed quote escaping in production Rustflags to ensure correct parsing and prevent runtime/config issues. Major bugs fixed: - Quote escaping bug in production rustflags (#6401) resolved, reducing risk of misconfiguration and build failures. Overall impact and accomplishments: - Enhanced business value through more accurate LP analytics, enabling better governance and decision-making; broader asset support expands user reach and product capability; improved test framework reduces regression risk and accelerates iteration; production build/config reliability improved through a critical rustflags fix. Technologies/skills demonstrated: - Rust, FixedU128 precision, BTreeMap-based storage, Substrate-like governance calls, multi-asset integration, and testing framework modernization with Chainflip IO.

Sep 1, 2025In September 2025, the backend work focused on migrating from the Polkadot chain to AssetHub, delivering a consolidated asset model, and decommissioning Polkadot-specific assets and configurations. The migration includes canceling all Polkadot orders, transferring remaining Dot balances to HubDot, and consolidating assets on AssetHub. The effort also established migration tooling, enhanced tests, and runtime/API changes to support AssetHub, with emphasis on reliability, maintainability, and business value.

Apr 1, 2025April 2025 (2025-04) focused on delivering a modern RPC API surface for chainflip-backend and improving runtime reliability. Key outcomes include RPC API modernization and modularity with a dedicated cf-rpc-apis crate, centralization of LP and Broker APIs on the state chain node, and CI/config updates to support the new API structure. A major bug fix addressed Subscription GC reliability by correcting LRU cache behavior, standardizing Subscription ID as String, ensuring consistent use of the chain head client across Subscription and GC, and extending node runtime capacity. These efforts improve API consistency, maintainability, scalability, and runtime stability, enabling faster feature iteration and stronger business value.

Dec 1, 2024December 2024: Delivered significant backend enhancements for data streaming and vault swap operations in chainflip-backend. Implemented a Unified Custom RPC Subscription Layer for Core Data Streams, centralizing block event, transaction screening, and order fill subscriptions to improve consistency, maintainability, and performance. Refactored broker API subscriptions and migrated the order fills API to the custom RPC path, reducing duplication. Introduced Bitcoin Vault Swap Expiry Support by encoding expires_at and aligning expiry with rotation cadence, with tests and runtime updates to validate correctness. Result: stronger data reliability for clients, simpler subscription model for future work, and improved safeguards for time-bound vault swaps. Tech highlights include RPC design, event-driven subscriptions, test-driven validation, and backend refactoring.
