Dec 1, 2024December 2024 monthly delivery focused on expanding vault-enabled liquidity operations, refining fee economics, and hardening mathematical primitives. Key outcomes include vault swaps with boost integration, enhanced deposit fee data and events, revenue capture via network fees on boosts, and a new minimum network fee per swap chunk. Fixed-point math robustness improvements reduce panics, improve overflow handling, and improve nth-root accuracy, complemented by readability gains across math modules. Stabilization efforts also addressed a pool orderbook panic, contributing to operational reliability. These workstreams collectively elevated business value by enabling vault-based liquidity, tightening fee economics, and reducing runtime risk while showcasing expertise in Rust/Substrate with performance-conscious design.
