Electrum-GRS

Electrum‑GRS is a lightweight client for the Groestlcoin cryptocurrency that operates on Windows, macOS and Linux through a client‑server protocol. By connecting to remote servers, it avoids downloading the full blockchain, making it suitable for users who want a fast, low‑resource wallet while still keeping their private keys locally. The wallet supports multi‑signature accounts, allowing several parties to co‑sign transactions, and includes features such as a notes tab for encrypted text, configurable log retention, and a swap‑server plugin for atomic swaps.

The interface provides standard wallet functions—address management, transaction creation, and balance display—while handling BIP‑21 URIs, fiat‑balance sorting, and customizable fee units. It integrates with hardware devices like Trezor, supporting extended PIN lengths, multiple change outputs, external pre‑signed inputs, and SLIP‑19 ownership proofs. Users can add server bookmarks and benefit from incremental wallet file writes that improve reliability.

Developed with a focus on stability, the application incorporates recent fixes for callback logging, SSL configuration, and race conditions in the setup wizard. It is packaged for various Linux distributions, macOS Homebrew, and includes updated security libraries, offering a secure yet convenient thin‑client experience for ordinary Groestlcoin users.
