DragonX (DRGX) Full-Node Desktop Wallet — v2.0.0
This is ObsidianDragon, a native ImGui-based wallet for the DragonX network. It ships with an embedded full-node daemon (dragonxd) and an integrated CPU miner (DRG-XMRig), giving users a complete, self-contained experience on Linux, Windows, and macOS.
What's New in v2.0.0
v2.0.0 is a major release. It adds end-to-end encrypted HushChat messaging and BIP39 seed-phrase wallets (with migrate-to-seed for legacy wallets), lets the wallet update its own node and miner with each install cryptographically verified, and ships a security-hardening pass across the updater, RPC, and secret-storage surfaces — plus full support for the new multi-threaded dragonxd and a large stability and UX overhaul.
New Features
- Encrypted messaging (HushChat) — new Contacts and Chat tabs bring DRGX-native, end-to-end encrypted messaging. Your chat identity is derived from your wallet seed, messages are encrypted with libsodium (XChaCha20-Poly1305 / secretstream) and stored in a seed-encrypted local database, and the wire format is interoperable with SilentDragonX / SilentDragonXLite.
- BIP39 seed-phrase wallets & migrate-to-seed — new wallets are backed by a mnemonic seed phrase you can back up from Settings. Existing legacy wallets can be migrated into a seed wallet — the wallet mints a new mnemonic wallet, sweeps your funds to it, and adopts it only once the sweep is mined, keeping a timestamped
wallet.datbackup throughout. (The bundleddragonxdsupports the required mnemonic RPCs; older nodes degrade gracefully.) - In-app daemon updater — Settings → Node & Security → Daemon binary → "Check for updates…" downloads the latest
dragonxdfrom the project Gitea, verifies its SHA-256 and a detached ed25519 signature before installing, and replaces the binary atomically while the node keeps running (the new build takes effect on the next daemon start). A two-pane version picker lets you pin, downgrade, or install any published/pre-release build. - In-app miner updater — an "Update miner…" action in the Mining tab fetches, verifies (SHA-256 + ed25519), and installs the latest DRG-XMRig, with the same version picker and a display of current vs. latest.
- Daemon binary management — the wallet no longer auto-overwrites a node you've dropped in; a dedicated Settings panel shows the managed binary and gathers all node actions (restart, rescan, repair) onto one toolbar.
- Repair Wallet — a one-click
-zapwallettxes=2recovery in Settings, plus automatic wallet reconciliation after a bootstrap and runtime rescan support for pruned nodes. - Explorer search — fuzzy, live (debounced) filtering of the block list by partial hash or height.
- History sorting & fast load — sort transactions by date or amount, a "Loading older history (N%)" indicator during the initial bulk load, and persisted history that surfaces pending sends immediately.
- Smarter mining — the thread benchmark now measures sustained (thermally-throttled) hashrate instead of an inflated initial burst, with GPU-aware idle mining and corrected idle thread scaling.
Security & Integrity
- Mandatory signature verification — both the daemon and miner updaters require a valid ed25519 signature (checked against a key pinned in the wallet) in addition to the SHA-256; an install is refused if the signature is missing or invalid.
- Hardened secret handling — RPC credentials are wiped from memory after use, RPC responses are size-capped and scrubbed of secrets in logs, generated node config is written owner-only (0600), and secrets copied to the clipboard auto-clear.
- Safe on-disk writes — settings, address book, and secret files are written atomically with owner-only permissions; the PIN vault fsyncs its secure-delete overwrite; SQLite cache growth is bounded.
- Recipient validation — sends validate recipient address checksums (Base58Check + Bech32) before building a transaction.
- Path-traversal protection — archive extraction (chain bootstrap and the updaters) rejects any entry that would escape the target directory (zip-slip), and the bootstrap fails closed on a missing checksum rather than trusting an unverified archive.
- Robustness — malformed RPC error JSON is guarded and sends are single-flight, preventing duplicate/ill-formed submissions.
Improvements
- New multi-threaded daemon support — live Sapling note-witness rebuild progress, accurate sync-speed display, reliable rescan-completion detection, and RPC polling throttled during sync so block download isn't slowed.
- Networking — DragonX DNS seed nodes,
-maxconnectionspassed to the daemon, and a peer count that stays current on every tab. - Node resilience — non-blocking warmup so you can connect while the daemon is still initializing, a live daemon-console tail on the startup overlay, fast-failing connect probes, and mid-session disconnect detection that keeps the UI responsive (in-flight RPC calls abort cleanly on disconnect/shutdown).
- Address list — modernized with drag-to-transfer, labels, and view-only handling.
- UI / DPI — overlay dialogs scale correctly with the font/DPI setting, improved CJK font rendering, native language names in the language picker, and format-incompatible translations are rejected.
- Settings — an "Open data folder" button and confirmation modals for rescan and restart-daemon.
Bug Fixes
Extensive fixes across history (shielded-tx ordering, stuck "refreshing history" banners, unconfirmed-badge stickiness), sends (correct fee passed to z_sendmany, fast-lane worker restart on reconnect, note-selection fee-gap workaround), rescan (accurate completion detection, no false "complete", no per-second error flood), RPC (mid-session disconnect handling, stale-refresh invalidation), and UI layout/i18n. See the commit history for the full list.
Features
- Full-node wallet — send, receive, and verify DRGX transactions with a bundled
dragonxddaemon; no external setup required. - Self-updating — verify-and-install the latest node and miner from within the app (SHA-256 + ed25519 signature enforced).
- Encrypted messaging — built-in HushChat with a seed-derived identity, end-to-end encryption, and a seed-encrypted local message store, interoperable with SilentDragonX / SilentDragonXLite.
- Seed-phrase wallets — BIP39 mnemonic backup, and migrate-to-seed to upgrade a legacy wallet into a seed wallet.
- Built-in CPU mining — start/stop DRG-XMRig from the Mining tab with real-time hashrate and pool statistics, mine-when-idle support with configurable delay, and sustained-hashrate benchmarking.
- Multi-language UI — full internationalization covering 8 languages: German, Spanish, French, Japanese, Korean, Portuguese, Russian, and Chinese.
- Cross-platform — native builds for Linux (AppImage + zip), Windows (portable exe + zip), and macOS (universal DMG + .app); Linux/Windows x86-64, macOS Intel + Apple Silicon.

- QR code generation for receiving addresses
- Transaction history with memo support, date/amount sorting, and pending-send tracking
- Blockchain explorer with live block/transaction search
- Blockchain rescan and Sapling witness-rebuild with status-bar progress
