October 2025: Delivered stability and accuracy improvements for sentio-sdk by upgrading core chain dependencies and enhancing CLI template generation. Completed a patch-level upgrade of @sentio/chain (3.4.8 -> 3.4.11) across patches, refreshed related dependencies and lockfiles (including p-queue), and removed unused example importers to improve reliability and compatibility. Implemented dynamic Ethereum template generation that now replaces placeholder chain IDs with the actual chain ID and updates the wrapped token address for correct template generation. Fixed plasma explorer API in the chain module to restore correct data access.
