What is Eigenwallet?

Eigenwallet is a privacy-focused, open-source Monero wallet that doubles as a peer-to-peer exchange layer. Formerly known as UnstoppableSwap, the project rebranded to reflect its expanded scope beyond atomic swaps alone. As of 2026-05-30, it offers full wallet functionality for XMR alongside trustless BTC-to-XMR swaps, with all network traffic routed through Tor by default.

The software is community-funded and donation-sustained, with no venture backing or token economics. Development is public and auditable on GitHub, with releases signed for verification. The latest stable version is v4.7.9, published 2026-05-29.

How no-KYC is it?

Eigenwallet operates with no registration, no accounts, and no identity verification at any stage. The atomic swap protocol itself enforces trustlessness-neither party can steal funds, and neither party learns the other's identity. The project's own materials state "no kyc ever" as a protocol guarantee.

The only fiat on-ramp, SEPA transfers for EUR-to-XMR purchases, is explicitly EU-only and appears to operate without KYC based on current site claims. Users should verify this independently, as SEPA rails typically carry bank-level visibility even when the endpoint does not require ID.

Privacy & security

Privacy is architecturally deep rather than surface-level. Key features include:

• Built-in Tor integration via Arti, with every peer receiving a .onion address
• No clearnet fallback for swap negotiation-everything runs over Tor
• Self-custodial keys with no server-side wallet data
• Open-source codebase (AGPL-3.0) with reproducible builds

The changelog shows active hardening: v4.7.9 added malicious-swap detection (refusing cooperative XMR redemption when BTC received is under 75% of expected), and v4.6.3 implemented Tor dial concurrency limits to prevent embedded Tor client overload. These are substantive, not cosmetic, improvements.

Third-party reputation is thin but not alarming. Trustpilot shows only 2 reviews as of this crawl. One gridinsoft scan flagged the domain with a 48/100 trust score citing recent registration and low third-party reputation-plausible for a rebranded project with limited mainstream footprint, though not indicative of malfeasance.

Payments, fees & limits

Eigenwallet itself is free software. Costs arise at the protocol level:

• Atomic swaps: Fees are negotiated peer-to-peer with individual market makers; no platform fee structure exists. The GUI and ASB now reject swaps where fee estimates diverge too far (v4.6.6).
• Liquidity range: As of late May 2026, active offers span 0.000010 BTC to 21.4682 BTC maximum, with most market makers clustering in the 0.001-2 BTC range. Daily average price has held near 0.005387 BTC/XMR.
• SEPA on-ramp: Available for EU users buying XMR with EUR; specific fees not disclosed in crawl data.

Network liquidity is visible in real-time on the project's liquidity page, with maker uptime ranging from 2 days to 300 days. Several makers have been inactive for 30-130 days, suggesting liquidity can be lumpy for larger swaps.

User experience & support

Eigenwallet targets desktop users with native builds for Linux (AppImage, Debian, Flatpak, AUR), macOS (Silicon and Intel DMG), and Windows. Mobile support remains "coming soon" per the site-a longstanding promise that should factor into platform decisions.

The interface is built in Rust/Tauri after an earlier Electron iteration was scrapped, suggesting performance prioritization. Native Monero C++ bindings replaced the heavier monero-wallet-rpc dependency, reducing attack surface and resource use.

Documentation is incomplete: the site notes "Docs (work in progress)" persistently. Users comfortable with CLI tooling have more options, including runtime configuration of external Bitcoin redeem addresses (v4.6.1) and detailed swap state inspection via controller commands.

Who it's for

Eigenwallet suits privacy-maximalists who want non-custodial XMR storage with occasional, trustless BTC conversion-without touching centralized exchanges. The Tor-only networking and atomic-swap architecture make it ideal for users in jurisdictions with restrictive financial access or those simply avoiding exchange surveillance.

It is less suitable for frequent traders needing deep liquidity, mobile-first users, or those seeking integrated fiat off-ramps. The learning curve and desktop-only availability create friction for casual users. For pure wallet needs, Feather Wallet remains a mature alternative; for swap-specific needs, Haveno or Bisq offer different liquidity models.
