During their tenure, rjakabosky contributed to the xuelongqy/wallet-core repository by engineering a Rust-based integration for Polkadot and Substrate, transitioning the codebase from C++ to modular Rust crates. They focused on expanding multi-chain support by implementing transaction building, address encoding (SS58), and SCALE serialization for networks including Polkadot, Kusama, and Polymesh. Their work included extracting Polymesh functionality from the Polkadot code, enabling independent transfers and staking, and registering Polymesh in blockchain registries. By updating build configurations and tests, rjakabosky established a maintainable, Rust-centric foundation that improved cross-chain interoperability and streamlined future wallet-core development.
March 2025 – Wallet-core: Delivered Polymesh blockchain integration by extracting Polymesh functionality from the Polkadot codebase, enabling Polymesh transfers and staking. This included registering Polymesh in blockchain registries, defining its coin type, and implementing address derivation and transaction signing. The work is documented in commit 9ede1155072a8c2ea50f7bc7fecf2f8603b336e9, reflecting the refactor that splits Polymesh from the Polkadot implementation (PR #4229). No major bugs fixed this month. Overall impact: expanded cross-chain support, improved maintainability through modularization, and increased business value for Polymesh users.]
