Polymesh SDK

Responsibilities & Contributions

Core SDK Development

Contributed to the development and stabilization of core Polymesh SDK functionality, with a focus on accurately modeling on-chain behavior for assets, compliance, permissions, and governance-related workflows.

Implemented and refined SDK methods related to transfer restrictions, exemptions, claims, and proposal handling, ensuring input validation and behavior aligned with protocol expectations and real-world usage.

Improved the consistency and safety of the SDK API surface by addressing edge cases, fixing incorrect query logic (e.g. claim expiry handling), and tightening validation for complex operations such as setting transfer restrictions.

Worked across multiple SDK beta releases, contributing fixes and enhancements that matured over successive versions rather than one-off feature drops.

SDK Stability, Correctness & Backward Compatibility

Identified and fixed core correctness bugs in SDK behavior that surfaced during integration (e.g. transfer restriction handling, claims queries), reducing runtime errors for downstream consumers.

Contributed to maintaining backward compatibility across SDK versions by ensuring new functionality and fixes did not introduce breaking behavioral changes for existing integrators.

Acted as an integration feedback loop between SDK usage (including REST-layer consumption) and SDK implementation, helping surface protocol–SDK mismatches early in the release cycle.

API Surface Consistency Across SDK, REST & Chain

Contributed to aligning SDK abstractions with REST API and on-chain capabilities, helping ensure that equivalent concepts (e.g. compliance rules, permissions, governance actions) behaved consistently across layers.

Added and refined SDK helpers (such as proposal-related constructs and richer query methods) to reduce the need for integrators to assemble low-level primitives manually.

Helped close functional gaps where on-chain features existed but were difficult or error-prone to access via the SDK.

Developer Experience & Type Safety

Improved TypeScript typings, generics, and input validation, increasing correctness guarantees at compile time and reducing ambiguous runtime failures.

Enhanced SDK usability by making complex operations more discoverable and less error-prone through clearer method signatures and stricter validation.

While not a primary documentation owner, contributed indirectly to developer experience by improving the reliability and predictability of SDK behavior, reducing the need for workarounds or defensive coding by consumers.

Results & Impact

• Improved the correctness and reliability of critical SDK functionality used by higher-level tooling (REST API, integrations, applications).
• Reduced integration friction by stabilizing compliance- and permission-related SDK flows that are central to institutional use cases.
• Strengthened the SDK as a trustworthy abstraction over Polymesh protocol behavior, supporting its role as the foundation of the broader developer ecosystem.
• Contributed to smoother SDK release cycles by incrementally maturing features across beta versions rather than introducing destabilizing changes.
