Apr 1, 2026April 2026 (2026-04) monthly summary for Aztec Protocol's aztec-packages: Delivered reliability-focused bug fix, introduced runtime-length array support for notes, and completed a broad code quality and maintenance sprint. The tag computation bug for invalid recipient addresses was fixed to return a random tag and prevent oracle failures, with tests ensuring transaction log integrity. A new dynamic array capability was added to the note getter, enabling runtime-driven sorts and selects for better flexibility and scalability. Extensive refactoring removed dead code, standardized class hash usage, simplified field comparisons, and updated documentation. The combined changes improve transaction reliability, developer efficiency, and system maintainability, delivering business value through safer transactions, scalable data handling, and cleaner codebase.

Mar 1, 2026March 2026 monthly summary for AztecProtocol/aztec-packages. The month delivered a set of security, reliability, and developer-experience improvements across the package, with multiple compile-time checks, standardized logging and naming, and API enhancements. Key features shipped this month reduce risk, improve observability, and simplify downstream integration, while API changes and observability enhancements pave the way for easier maintenance and faster iteration. Key features delivered: - Compile-time size checks for events and error code links with static asserts and docsite integration, preventing packing-length issues and guiding future handling via docs. - Prefix aztec-nr contract logs with the [aztec-nr] tag to improve log routing and filtering. - Improve oracle name prefixes with the aztec namespace, standardizing prefixes and tightening error-message routing for Noir/Nargo workflows. - Add aztecaddress::is_valid for address validation to catch invalid inputs early. - Extend env.deploy with salt and secret parameters via a deploy_opts function, enabling more secure and configurable deployments. - Add note hash and nullifier helper functions with domain separation to strengthen hashing practices and centralize domain separation logic. - Improve L2ToL1MessageWitness API (breaking change) to remove epoch requirements and support message-based querying, with an optional messageIndexInTx for disambiguation and a new getCheckpointsDataForEpoch helper. - Add public log filtering by tag to enhance observability and debugging capabilities. Major bugs fixed: - Fix: claim contract and improve nullif docs, replacing direct nullifier pushes with a safer SingleUseClaim flow and clarifying docs around nullifiers. - Fix: search for all note nonces instead of only the nonce for the note index to improve correctness and resilience. - Fix: use anchor block on getL1ToL2MsgWitness to stabilize lookups. - Fix: ensure queries are not made ahead of the anchor block to avoid future-dated results. - Fix: disallow infinite pubkeys to prevent invalid inputs from destabilizing the system. Overall impact and accomplishments: - Strengthened security posture through improved domain separation, safer hashing, and deployment controls. - Improved developer experience via API simplifications, standardized naming, enhanced observability, and clearer logging. - Enabled more robust operations with better filtering, input validation, and resilience against edge cases. Technologies and skills demonstrated: - Rust code improvements, static analysis and compile-time checks, domain separation concepts, enhanced observability tooling, and API design refinements. Business value: - Reduced risk in deployments and transaction processing, faster issue diagnosis through consistent logs, and smoother downstream integration with updated APIs and standard prefixes.
