Nikhil worked on the xuelongqy/wallet-core repository, delivering features that enhanced blockchain wallet reliability and maintainability. He migrated Barz and Ethereum Address APIs from C++ to Rust, improving memory safety and cross-platform compatibility, and expanded Flutter bindings to support wallet creation and signing in Dart. Nikhil addressed large-value TON transfers by implementing big-endian uint128 encoding, ensuring accurate transaction processing. He also enabled sponsor-enabled token transfers on Solana, refactoring the message builder for conditional logic and adding robust tests. His work included CI/CD improvements, code coverage analysis, and terminology updates, demonstrating depth in Rust, Dart, and protocol implementation.

Oct 1, 2025October 2025: Delivered a focused refactor in the Solana module to rename fee_sponsor_token_address to fee_recipient_token_address, aligning terminology with its use in token transfers and fees. This improves readability, reduces risk of misinterpretation, and enhances maintainability for future enhancements. The change is isolated, low-risk, and well-documented (commit 1efc1c10b836d52f748bf7f71929cf0f9bb0b163) in wallet-core xuelongqy/wallet-core (#4528). No major bug fixes this month. Business value: safer onboarding for new engineers and fewer token-fee misconceptions.
