November 2025 monthly summary for near/nearcore focusing on documentation improvements around deterministic account IDs aligned with NEP-616. Delivered clear, actionable documentation for deterministic account IDs and related actions for global contracts, improving developer onboarding and integration with the protocol.

Monthly summary for 2025-10 focused on delivering a deterministic account lifecycle and initialization framework, with robust deployment mechanics and storage correctness, alongside NEP-616 sharded-contract and VM runtime improvements. This period established the core deterministic account capabilities, expanded host functions, and laid groundwork for end-to-end testing and performance gains.

September 2025 monthly summary focusing on foundational deterministic account work and enhanced refund routing in near/nearcore. Key initiatives delivered include: feature flag and infrastructure for deterministic account IDs, deterministic state initialization (NEP-616) with Action::DeterministicStateInit, and corresponding gas parameter support; introduction of refund routing to the original signer via host function promise_set_refund_to, with updates to ActionReceipt to support refunds and a versioning strategy; codebase adjustments such as moving GlobalContractIdentifier to near-primitives-core to enable VM/runtime access for account-id derivation; comprehensive tests for host function invocation and refund routing. These changes strengthen security, predictability, and a smoother path to sharded contracts and improved gas accounting.

August 2025: Delivered documentation for the gas refund mechanism in near/docs, clarifying that the current refund fee is 0 and presenting a future plan to calculate refunds based on unspent gas. Updated the related refund penalty numbers (#2718) and prepared stakeholders for upcoming changes. No major bugs fixed in this repository this month. Business impact includes clearer policy, improved developer/user onboarding, and alignment with the roadmap for a dynamic refund model.

Month: 2025-07 — near/nearcore improvements focused on transaction processing reliability and correctness. This month delivered key fixes for chunking recovery robustness and refunds/receipts handling per NEP-536, along with targeted tests and robust JSON-RPC behavior.

Monthly summary for 2025-05 focusing on near/docs: Gas refund mechanism updates per NEP-536 and Protocol v78; documentation changes reflecting fixed gas price per transaction and introduction of a gas refund fee for unspent gas to improve network efficiency by discouraging excessive gas attachment. No major bugs fixed in near/docs this month; documentation alignment completed to reflect protocol changes and their impact on gas usage.

April 2025 near/nearcore monthly summary: Focused on stabilizing RPC transaction processing and advancing NEP-536 gas pricing reforms. Key reliability improvements were delivered by replacing the deprecated broadcast_tx_commit with send_tx to ensure finality is awaited, strengthening integration-test stability and refund receipts. In parallel, NEP-536 adoption progressed with the enablement of ReducedGasRefunds and removal of refunds for gas price changes, complemented by a targeted refactor of test utilities to support flexible receipt counts for NEP-536 testing. These changes improve transaction finality reliability, reduce gas refund variance, and enhance test coverage, enabling safer gas-pricing experimentation and more predictable client integrations. Key achievements for the month: - RPC Transaction Handling Reliability: Replaced deprecated broadcast_tx_commit with send_tx to ensure finality waits, improving integration-test reliability and refund receipt correctness. Commit: 978db05d8217e6587af0d343a1d0dea4edcb8dd9. - NEP-536 Gas Pricing Reform Implementation: Enabled ReducedGasRefunds protocol feature and disabled refunds of gas price changes to align with NEP-536. Commits: 8fc700f780ee8a12bf255694550e1343145c5dff; 0b4ed19f799a4e80fcc7b5a7246694f8b493075d. - Test Framework Refactor for NEP-536 Testing: Refactored test utilities to support flexible receipt counts and remove legacy macros to improve NEP-536 test coverage.
