WHAT'S INSIDE

Inside the wallet stack

The app is built as three concrete layers — Vault, Routing, and Operator Console — so you always know what protects keys, what moves funds, and what you control.

Local-first

The wallet stack

Every feature in the app belongs to one of three layers. Together they form a stack that’s predictable to reason about — even under stress.

  1. 01 · Vault Keys, seed phrases, and cold storage. Argon2id + OS keychain, hardware wallets, multisig, encrypted backups.
  2. 02 · Routing How your USDT actually moves. Multi-chain adapters, FREE Gas (Energy) relays, fee estimator with manual override.
  3. 03 · Operator console Your day-to-day control surface. Policies, offline mode, readable errors, and a versioned changelog.

The feature cards on the right are grouped by layer, so you can quickly see what protects what. Learn how these layers interact in the security model and the networking docs.

Vault layer

Keys stay on your machines

  • At-rest encryption via Argon2id plus the OS keychain.
  • Hardware wallets (Ledger & Trezor) with on-device confirmation.
  • Full M-of-N multisig with named cosigners and clear prompts.
  • Seed export with human-readable verify lines for cold backups.

Multisig setup guide

Routing layer

FREE Gas & fee control

  • Multi-chain adapters for major USDT networks with predictable fees.
  • FREE Gas (Energy) relay network with health checks and fallbacks.
  • Advanced fee estimator with manual override when you need it.
  • Exact receive-amount preview before every send.

See Networking & FREE Gas docs for technical details.

Operator console

Built for power-users

  • Offline mode for air-gapped review and signing packs.
  • Per-wallet policies: limits, approvals, and labels.
  • Reproducible, deterministic builds with an in-app changelog.
  • Readable errors with “what you can safely do next”.

Changelog

A concise history of how the app evolves: performance, security, and UX — without the marketing fluff. For a deeper security and threat model overview, see the security docs.
