Monthly summary for 2025-12 (alloy-rs/alloy). Implemented Ethereum transaction receipt subscription within the pub-sub model. Added a new SubscriptionKind variant (transactionReceipts) and full serialization/deserialization for subscription parameters, enabling real-time updates on matching receipts. Implemented strict unknown-field validation to catch misconfigurations and improve robustness. This feature enhances real-time visibility and responsiveness for Ethereum workflows, enabling downstream services to react to receipts with lower latency. Collaborative contribution reflected in the commit history.

November 2025 (2025-11) monthly summary for xuelongqy/wallet-core: Focused stability improvements in base64 encoding paths. Delivered a targeted fix to the NO_PAD constant to ensure proper padding during encoding, preventing potential data corruption in serialization paths. The change was implemented as part of issue #4487 and committed as 5afbb3ea8e6319ec3630f5c5a6958ee72a1b61bf, with co-authorship credited to Sergei Boiko.

Concise monthly summary for 2025-10 focusing on BOR repository deliverables. Real-time transaction receipts subscription delivered via WebSocket, enabling clients to subscribe to all receipts in new blocks or specific hashes, reducing RPC polling and latency. This month, no major bug fixes were recorded for this repo; feature work drove performance and scalability improvements and business value through real-time monitoring.

September 2025 monthly summary for wallet-core focused on strengthening JNI input validation and crash resilience. Key achievement: replaced SIGSEGV-based null checks with IllegalArgumentException and introduced robust null-check macros, applied across signing and planning functions to prevent crashes caused by null or invalid inputs. These changes reduce crash risk, improve input validation, and enhance maintainability at the JNI boundary. Business impact includes more predictable behavior, easier debugging, and higher reliability in production pathways that involve signing and planning workflows. Commit reference: 3c1f86c4e33059b397e4a265949697d591ffd296 with message Throw exception rather than SIGSEGV (#4443).

Concise monthly summary for 2025-07: Implemented Tron raw JSON transaction compilation and signing in xuelongqy/wallet-core, enabling DApps to construct and sign Tron transactions directly from raw JSON data, extracting txID and raw_data_hex, and incorporating signatures into the final JSON. This streamlines end-to-end Tron transaction workflows and improves interoperability with DApps.

June 2025 monthly work summary for the wallet-core project, with a focus on enhancing Solana transaction construction and API ergonomics. Delivered a targeted feature to insert Solana instructions at a specified index within a transaction, and updated API naming to reflect the expanded capability. This work improves precision of transaction ordering, developer experience, and reliability for complex Solana workflows across the wallet-core repo.

Concise monthly summary for May 2025 focused on xuelongqy/wallet-core. Delivered a targeted feature enabling EIP-7702 Authorization Parameter support within EIP-4337 user operations, along with tests to ensure correct behavior and compatibility.

April 2025 monthly summary for xuelongqy/wallet-core focusing on key features delivered, major bugs fixed, impact, and technologies demonstrated. Highlights include enabling EIP-7702 signing via external sign servers (AWS KMS or similar) with pre-signed and internal options and refactored multi-workflow authorization; Solana transaction instruction management with base58-encoded data support and new InsertInstruction/SolanaTransaction; fixed encoding order in UserOperation v7 and improved JSON parsing for TWStoredKey. These efforts deliver business value by expanding secure signing surface, ensuring reliable multi-chain transaction construction, and improving build stability and test coverage.

January 2025: Delivered cross-chain wallet-core enhancements across Ethereum, Solana, Sui, and Substrate, enabling function signature extraction, multi-sig transaction preparation, personal message signing, and deterministic transaction hashing. A key bug fix improved Solana multi-signature compilation by initializing key_signs with existing signatures. These changes drive greater interoperability, security, and developer efficiency, reducing integration time for new chains and assets while improving auditability and user trust.

December 2024 monthly summary for xuelongqy/wallet-core: Delivered Solana Transaction Enhancements including Partial Signatures and Fee Payer support, enabling DApps to assemble transactions with a subset of required signatures and to designate the fee payer. This strengthens Solana compatibility and multi-party signing workflows, reducing integration friction and expanding business use cases.

Monthly summary for 2024-11 focused on delivering cross-platform Bech32/Bech32m encoding support in wallet-core, with tests and library integration. The work enhances interoperability across platforms and provides a solid foundation for future protocol updates and platform-specific integrations.
