Smirk: Non-Custodial Tipping Wallet

Tip Bitcoin, Litecoin, Monero, Wownero, and Grin directly from your browser. Your keys stay in the extension — the server never has access to your funds.

How it works

Smirk is a browser extension wallet that lets you send and receive crypto tips on social platforms like Telegram and Discord. Unlike traditional tip bots that hold your coins on a server, Smirk keeps your private keys in the browser. The backend acts as a relay — it can't decrypt your tips or access your funds.

All transactions are on-chain. No IOUs, no internal ledgers.

Supported assets

- Bitcoin (BTC) & Litecoin (LTC) — on-chain tipping via link drops using Electrum servers
- Monero (XMR) & Wownero (WOW) — the first browser extension wallet for Monero and Wownero, powered by Light Wallet Server (LWS) with client-side key image scanning for full privacy
- Grin (GRIN) — Mimblewimble transactions including interactive slatepack exchange and async vouchers

Features

- All transactions on-chain — every tip is a real blockchain transaction, not an entry in a database
- Tip by social handle — send to Telegram or Discord usernames without needing a wallet address
- One-click claims — recipients install the extension and claim tips with a single click
- Clawback — reclaim unclaimed tips using your local encrypted backup
- Multi-asset wallet — manage BTC, LTC, XMR, WOW, and GRIN from one interface
- Grin slatepack support — send, receive, and pay invoices using the full SRS and RSR flows
- Real-time balance — pending and locked amounts displayed as transactions confirm

Architecture

- Non-custodial — keys derived client-side, encrypted with your password, never sent to the server
- ECIES encryption — tips encrypted in the browser before transmission
- WASM cryptography — Monero and Grin operations run in WebAssembly for correctness and performance
- Manifest V3 — built on Chrome's current extension platform
- Rust backend — for performance and safety
