Full native-quality Traditional Chinese (Taiwan) locale covering all 910 keys. Shared GRIM-inherited keys use jasperli2026's zh-TC values verbatim; goblin.* namespace translated from the corrected Simplified source into Taiwan-idiom Traditional (OpenCC s2twp plus a manual Taiwan post-fix and review pass), keeping Jasper's voice and crypto-wallet register. Cangjie keyboard labels reused from zh-CN; lang_name set to 繁體中文. Wired into the i18n drift test (OTHER_LOCALES) and README attribution; rust_i18n auto-loads it and the language picker labels it via lang_name. System locale zh-TW auto-selects; news folds zh-TW to zh (shared with Simplified) as noted in news_locale_code.

# Goblin
|
|
|
|
Goblin is a private, pay-by-username wallet for [GRIN ツ](https://grin.mw) - confidential digital cash on [Mimblewimble](https://github.com/mimblewimble/grin), with no amounts or addresses on the chain.
|
|
|
|
Instead of passing slatepack files back and forth, you **pay a `username` (or an `npub`)** and the payment is delivered for you as an **end-to-end encrypted message over [nostr](https://github.com/nostr-protocol/nips), routed through [Tor](https://www.torproject.org)**. Relays only ever see ciphertext - never the amount, the sender, or the recipient. Tor hides your IP from the relay; the relay and encryption hide the rest - content, sender, timing.
|
|
|
|
Goblin is a fork of the **Grim** egui GRIN wallet: it keeps Grim's full GRIN node/wallet engine and layers a Nostr-native, mobile-first payments experience on top.
|
|
|
|
## What it does
|
|
|
|
- **Send to people** - pay a `username` or `npub`; the GRIN slatepack travels as a [NIP-17](https://nips.nostr.com/17) gift-wrapped DM ([kind 1059](https://nostrbook.dev/kinds/1059)) over Tor and is applied automatically by the recipient's wallet. No files to swap, no need to both be online at once.
|
|
- **Manual slatepacks too** - when you need to pay or get paid without a handle, **Settings → Wallet → Slatepacks** exposes the classic by-hand flow: create a slatepack to send, or paste one to receive, finalize, or pay.
|
|
- **Open-to-pay links** - a `goblin:` or `nostr:` pay link, or a scanned checkout QR, opens the wallet straight to a prefilled review screen (recipient, amount and note filled in, ready to hold-to-send) on desktop, macOS and Android.
|
|
- **Proofs on request** - payments can include a native Grin payment proof when the payment request asks for one, off by default, shown on the review screen. An ordinary person-to-person send carries none.
|
|
- **In-app identity** - a nostr payment key that is deliberately *not* part of your seed, so you can rotate it any time to stay unlinkable without touching your funds. An optional human-readable `name` comes from the goblin.st identity service.
|
|
- **Private by construction** - GRIN's address-less, confidential chain; your payments and identity (nostr relays, NIP-05 lookups, price) are routed through [Tor](https://www.torproject.org), so who-pays-whom never touches the clear net. The GRIN node connection - block sync and broadcasting your transaction - is direct: public chain data, the same for everyone, and not tied to your identity. Keys, names and history stay on your device.
|
|
- **Configurable amount pairing** - show balances against a world currency, Bitcoin, or sats (rates fetched over Tor), or turn the preview off.
|
|
- **News on Home** - the latest post from the official Goblin news key (a [kind 30023](https://nostrbook.dev/kinds/30023) long-form article) appears on the Home screen in your wallet's language, falling back to English; it stays hidden when there is nothing to show, and only ever shows the newest article.
|
|
- **Cross-platform** - Linux, macOS, Windows, Android, built in pure Rust on [egui](https://github.com/emilk/egui).

## How a payment travels
|
|
|
|
```
|
|
you ──slatepack──▶ NIP-17 gift wrap (kind 1059, NIP-44 encrypted)
|
|
│
|
|
Tor
|
|
│
|
|
┌─────────────┴─────────────┐
|
|
your relays recipient's DM relays (kind 10050)
|
|
└─────────────┬─────────────┘
|
|
▼
|
|
recipient ◀──unwrap, verify seal author, apply slatepack
|
|
```
|
|
|
|
The wrap is [NIP-44](https://nips.nostr.com/44)-encrypted, and delivery uses the recipient's DM relay list ([kind 10050](https://nostrbook.dev/kinds/10050)). Tor hides your IP from the relay; the relay and the encryption above hide the rest - content, sender, timing.
|
|
|
|
Both parties only need one relay in common. The default set is the Floonet relay (`relay.floonet.dev`) plus Tor-friendly public relays (`relay.0xchat.com`, `offchain.pub`) that accept connections from Tor exits, and the set is editable in **Settings → Relays**.
|
|
|
|
## Build
|
|
|
|
### Desktop (Linux / macOS / Windows)
|
|
|
|
Goblin links [Tor](https://www.torproject.org) **in-process** via [arti](https://gitlab.torproject.org/tpo/core/arti) - the wallet is a single self-contained binary, no sidecar, nothing separate to install:
|
|
|
|
```
|
|
git submodule update --init --recursive
|
|
cargo build --release
|
|
./target/release/goblin
|
|
```
|
|
|
|
Goblin's identity and payment traffic (nostr relays, NIP-05 lookups and price fetches) rides Tor: every relay, the money-path relay included, is reached over a Tor exit to its ordinary clearnet host. The GRIN node connection (block sync and transaction broadcast) is **not** routed through Tor: it connects directly, as it carries only public chain data that isn't linked to your wallet.
|
|
|
|
### Android
|
|
|
|
Install the Android SDK / NDK, then from the repo root:
|
|
|
|
```
|
|
./scripts/android.sh build|release v7|v8|x86
|
|
```
|
|
|
|
`v7`/`v8`/`x86` is the device CPU architecture for `build`; for `release` pass a version in `major.minor.patch` form.
|
|
|
|
## Identity service (`goblin-nip05d`)
|
|
|
|
The optional `name` service lives in `goblin-nip05d/` (axum + SQLite) and is deployed at [goblin.st](https://goblin.st). It implements [NIP-05](https://nips.nostr.com/5) resolution, [NIP-98](https://nips.nostr.com/98)-authenticated registration and release (names are never transferred - on a key rotation you release the old name and re-register, or import your existing identity). The wallet is fully usable - and fully anonymous - without it. Avatars aren't stored or served - clients render them from the pubkey (an npub gradient with the username's first letter, else the Grin mark).
