Sep 1, 2025

In September 2025, the Paladin project delivered two key features/quality improvements and expanded test coverage, strengthening reliability and business value. Enhanced error reporting around transaction assemblies and revert reasons reduced debugging time and improved incident triage. Fixed revert reason data type to prevent nil pointer issues, and broadened Pente domain test suites to validate deployments, state changes, approvals, and timestamp-related behavior across multiple contracts. Together these efforts improve deploy confidence, reduce production incidents, and demonstrate solid proficiency in Solidity/EVM testing, error handling, and test infrastructure.

Jul 1, 2025

July 2025 — Paladin (LF-Decentralized-Trust-labs/paladin). Delivered a key feature to retrieve IZetoKyc ABI and synchronize with the SDK ABI, and fixed a reliability bug by increasing ZKP proof generation timeout for slower systems during private transfers. This work automates ABI management and improves private transfer reliability, reducing manual intervention and support overhead.

Mar 1, 2025

Month: 2025-03 Paladin repository delivered three key features/improvements focusing on reliability, correctness, and maintainability. Key features delivered include: 1) Zeto ABI and Build Integration Enhancements — ensure correct ABI file paths, centralize ABI copying, and introduce a dedicated zetoArtifacts config for Gradle builds. 2) Zeto Core Transaction and Lock State Management Improvements — use the Locked flag to distinguish locked/unlocked outputs, condition inputs based on token type, and remove obsolete lockInfoSchema to simplify code. 3) Testing Infrastructure Consolidation — consolidate integration tests into domains/integration-test for better organization and workflows.

Feb 1, 2025

February 2025 highlights: Implemented domain initialization configuration for paladin, added a robust TransferLocked flow with completion after prepare, and expanded operator E2E tests to cover lock and transferLocked. Integrated Zeto lock API (lock, delegateLock, transferLocked) with alignment to the transferLocked workflow, and fixed ABI verifier ordering to ensure correct on-chain behavior. Introduced CopyZetoSolidity as a dependency for operator:make to streamline builds. Strengthened test coverage and hygiene with new unit tests and broader coverage improvements. These changes deliver secure, auditable asset locking, faster operator workflows, and a solid foundation for future Zeto-enabled features.
