Parv Tiwari developed and enhanced Lightning wallet and withdrawal features in the BitGoJS repository, focusing on robust API design, backend reliability, and cryptographic integrity. Over nine months, Parv delivered on-chain withdrawal capabilities, wallet generation, and PSBT validation, using TypeScript and Node.js to ensure secure, test-driven workflows. Their work included implementing withdrawal signing and verification, refining data models for Lightning payments, and improving error handling and traceability. By integrating comprehensive unit testing and strengthening dependency management, Parv addressed operational risks and improved user transparency. The depth of engineering demonstrated a strong grasp of Bitcoin protocol, backend development, and API integration.

October 2025 performance summary for BitGoJS: Delivered three focused changes that improve interoperability, configurability, and alignment with evolving type definitions. A critical bug fix now ensures non-standard extended key prefixes are correctly handled, eliminating processing errors with utxolib. A new optional parameters feature for lightning on-chain withdrawals adds flexibility and improves user control, with unit tests updated to cover scenarios. Updated core type dependencies to @bitgo/public-types 5.31.0 to reduce typing drift and maintain compatibility with downstream tooling. These changes collectively reduce operational risk, enhance onboarding for new users, and reinforce the platform's robustness.

September 2025 focused on strengthening Lightning withdrawals, refining PSBT handling, and upgrading Lightning-related infrastructure in BitGoJS. The changes delivered stronger PSBT integrity for Lightning withdrawals, standardized request handling while simplifying the API surface, and custody-aligned data model refactors. A targeted bug fix corrected the coin identifier in unsignedCoinSpecific to ensure proper processing, reducing risk in production usage.

In August 2025, delivered a security-focused enhancement to BitGoJS by implementing withdrawal signing and verification via the user authentication key for lightning on-chain withdrawals. The feature adds a passphrase requirement and an optional sequence ID/comment, and signs the withdrawal before submission. TypeScript codecs were extended to support the signature workflow (userAuthKey, signature, signedRequest) to enable end-to-end verification.

July 2025: Focused on improving withdrawal traceability and reliability for Lightning withdrawals in BitGoJS. Delivered a new withdrawStatus field and status propagation to provide end-to-end visibility from initiation to final outcome. The change wires the withdrawStatus through LndCreateWithdrawResponse and SendPsbtResponse, enabling clients to track progress, associated transaction IDs, and failure reasons, thereby improving customer transparency and troubleshooting. This work reduces ambiguity in withdrawal workflows and supports improved reliability and SLA adherence.
