Lastrum

Self-custody Liquid wallet — L-BTC, USDt, confidential transactions, native swap, cross-chain bridge. No KYC.

Lastrum is a non-custodial browser wallet for the Liquid Network — a Bitcoin sidechain built for fast, private, multi-asset transactions. ⚡ WHY REDBIRD • Self-custody — your seed never leaves your device • Confidential by default — Liquid hides amount and asset on-chain • Native Liquid swap (L-BTC ↔ USDt via SideSwap) • Cross-chain bridge (Bitcoin, Ethereum, Polygon, Solana and more via SideShift) • External Connect — dApps request signed attestations without ever touching your keys • No KYC, no account creation, zero analytics or third-party trackers 🔐 SECURITY • AES-256-GCM vault with Argon2id key derivation • Auto-lock on inactivity (key wiped from memory) • MV3 service worker with the minimum permissions required • Open-source client — auditable code (link in About) 🌐 LIQUID NETWORK Liquid is a Bitcoin sidechain operated by the Blockstream federation. Faster blocks (~1 minute), confidential transactions native to the protocol, and support for multiple tokenized assets (L-BTC, USDt, BRL-pegged stablecoins, RWA tokens). Lastrum brings Liquid into your browser with a UX modeled after MetaMask, focused on Bitcoiners who want native privacy and asset diversity without leaving the Bitcoin security model. 📚 DOCS & SUPPORT • Getting started: https://redbird.anchorkit.dev/help/getting-started • Terms of Use: https://redbird.anchorkit.dev/legal/terms • Privacy Policy: https://redbird.anchorkit.dev/legal/privacy • Risks & disclaimers: https://redbird.anchorkit.dev/legal/risks • Support: support@anchorkit.dev • Security disclosures: security@anchorkit.dev ℹ️ ABOUT Redbird is developed and operated by Quantum Tech Ventures, S.A. de C.V.
