Non-custodial multi-currency tip wallet for Telegram, Discord, and more

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 Getting started 1.
