How it works
Zeus is a self-custodial mobile wallet for Bitcoin and the Lightning Network, built in React Native and distributed for Android, iOS and F-Droid. It runs in two modes. Embedded mode bundles an LND binary inside the app, syncs the Bitcoin chain via Neutrino so the wallet never queries servers with the user's on-chain addresses, and manages channels on the device. Remote mode hands the app to an existing node — LND, Core Lightning or LNDHub — reachable over Tor or clear-net. Either way, keys are generated and held on the phone; there is no Zeus account, no hosted balance and no Zeus server in the payment path. Routing happens through the public Lightning peer graph itself.
KYC & privacy
There is no signup. No email, no phone, no captcha — the only setup choice is whether to encrypt the seed with a passphrase. Apple's privacy nutrition label, populated by the developer, declares no data is collected from the app. The codebase is AGPL v3, and reproducible builds are explicitly supported — which is what WalletScrutiny verified when it certified the Android binary against its seven self-custody tests. The optional ZEUS LSP service used for inbound liquidity adds a counterparty for that specific function, but the wallet itself stays in the user's pocket and the LSP role is documented rather than hidden.
Strengths and limits
The strongest argument for Zeus is durability. After the April 2024 indictment of the Samourai developers and Phoenix's US-market exit, founder Evan Kaloudis publicly committed to keeping Zeus self-custodial and available — "We're not going anywhere" — and shipped through the rest of the year regardless. In April 2026 the project completed a SOC 2 Type II audit with Prescient Assurance, an unusual move for a privacy-leaning wallet and one designed to onboard institutions to Lightning without forcing them to take custody of anyone's coins.
The limits are real. Running an embedded LND on a phone is more demanding than a typical wallet: battery, storage and a dependence on Neutrino peers mean a casual user has to let the app catch up periodically. Liquid and Cashu, both adjacent to Zeus's LSP-first design, are not native — users wanting either reach for another wallet. And the LSP convenience comes with the trade-off any custodial-liquidity arrangement has: convenience up front, channel constraints later.
Verdict
Zeus is the wallet a Lightning operator already runs, dressed in something a non-operator can also use without surrendering keys, identity or telemetry. It has behaved consistently for six years across three jurisdictions' worth of crackdowns, and paid for an audit it did not need to advertise. For anyone curious about Lightning who can spare the phone storage, this is the obvious starting point; for users who want nothing on a phone, run it remote against their own node — same wallet, same code.
Zeus is the wallet a Lightning operator already trusts, packaged so a non-operator can use it without surrendering keys, identity, or telemetry. Six clean years, an AGPLv3 codebase, and an audit it did not have to publish. Grade: A (9.4/10). Trust: LEGIT.
