+**DragonX (DRGX) Lite Desktop Wallet — v1.0.0**
+
+ObsidianDragonLite is a lightweight companion to the ObsidianDragon full-node wallet. It skips the embedded full node entirely — **no multi-gigabyte blockchain download and near-instant startup** — by connecting to a DragonX lite-wallet (lightwalletd-style) server, while keeping the same native ImGui interface and shielded-first workflow.
+
+This is the **first release** of the Lite variant.
+
+---
+
+## Why Lite?
+
+- **No blockchain to download.** Sync in seconds instead of hours; a few MB of state instead of many GB.
+- **Same wallet, lighter footprint.** The familiar ObsidianDragon UI, shielded and transparent addresses, and address book — without running a node or miner.
+- **Portable.** A single self-contained binary that stores its data in its own `ObsidianDragonLite` folder, so it coexists cleanly alongside the full-node wallet.
+
+---
+
+## Features
+
+- **Fast, node-free operation** — connect to a DragonX lite-wallet server and sync in seconds; minimal disk and RAM.
+- **Wallet lifecycle** — create a new wallet, restore from a seed phrase, or open an existing one; wallets auto-open on startup, with a first-run welcome prompt and **guided seed backup** on creation.
+- **Shielded + transparent** — send, shield, and receive DRGX; per-address balances computed from unspent notes and UTXOs.
+- **Keys & seed** — export your seed phrase and keys, and import keys, from Settings.
+- **Passphrase encryption** — encrypt, unlock, lock, and decrypt the wallet; you're prompted to unlock at send time and on startup when the wallet is locked.
+- **Encrypted messaging (HushChat)** — built-in **Contacts** and **Chat** with a seed-derived, **SilentDragonXLite-compatible** identity and a seed-encrypted local message store, so you can message other DragonX users end-to-end.
+- **Server management** — a built-in **server browser with automatic failover**; switch servers with live reconnect/recovery, and a **"Redownload blocks"** action to rescan from the server.
+- **Status & diagnostics** — a **Network tab** showing connection and sync status, plus an **interactive Console** for running backend commands and copyable error output.
+- **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 (DMG + .app), x86-64.
+- QR code generation for receiving addresses
+- Extensive theme and appearance options
+
+---
+
+## How it differs from the full-node wallet
+
+- **No embedded `dragonxd`, no mining, no local blockchain explorer.** Chain data comes from the lite-wallet server rather than being verified locally by a full node — a lighter footprint in exchange for trusting the server for chain state.
+- Everything key-related stays **on your device**: seed, keys, and (when enabled) the encryption passphrase never leave the machine.

+**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.dat` backup throughout. (The bundled `dragonxd` supports the required mnemonic RPCs; older nodes degrade gracefully.)
+- **In-app daemon updater** — Settings → **Node & Security → Daemon binary → "Check for updates…"** downloads the latest `dragonxd` from 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=2` recovery 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, `-maxconnections` passed 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.

+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 `dragonxd` daemon; 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.
+- Shielded (z-address) and transparent (t-address) send/receive
+- 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
+- Repair Wallet and daemon-binary management in Settings
+- Built-in console
+- Extensive theme and appearance options
