Monfluo is a minimal Monero-only Android wallet that prioritizes purity and low attack surface. This review examines its features, sync speeds, and installation options based on 2026 data.
Monfluo is a lightweight, open-source Android wallet built exclusively for Monero. It began as a fork of Mysu, previously known as MyNero, which itself forked from Monerujo. The project deliberately removes every feature outside core Monero functionality to keep the attack surface small and the code easy to audit.
Monfluo offers no support for other cryptocurrencies and ships without exchange rates, swaps, or fiat on- and off-ramps. Instead it supplies coin control for UTXO and enote management, Polyseed and 25-word seed support with optional passphrases, OpenAlias, multi-wallet and multi-account handling, and the option to select any custom node. The wallet stays fully non-custodial.
Its 2026 positioning targets users of de-Googled phones such as GrapheneOS. Installation occurs through direct APK from the Codeberg repository or the project’s own F-Droid repository at fdroid.monfluo.org with an onion mirror available. Reviewers note that this narrow focus and clean distribution path give Monfluo an edge for anyone who wants a minimal Monero client rather than a multi-coin platform.
Users can obtain Monfluo through a direct APK download from the Codeberg releases page or by adding its dedicated F-Droid repository. The clearnet repository address is fdroid.monfluo.org, with an onion mirror available for users who prefer Tor routing. Both paths deliver the same signed builds without requiring a Google account.
Version 0.9.7 reached the repository in late September 2026 after fastlane metadata updates on 2026-09-27. That release introduced security hardening by marking most activities and broadcast receivers as non-exported and added explicit DNSSEC failure warnings. The wallet incorporated the latest Monero core on 2026-10-16, bringing it to version 0.18.5.3.
Recurring operational costs listed in the repository README exclude developer time. A build server for CI/CD runs at 16 EUR per month, F-Droid infrastructure adds 8 EUR per month, and the monfluo.org domain costs 15 EUR annually. These figures remain modest because the project avoids paid marketing or third-party services.
Prospective contributors can verify the exact expense line items directly in the current Codeberg README before deciding on support methods such as donations or infrastructure sponsorship.
Monfluo provides coin control through direct UTXO and enote management, letting users select specific outputs when constructing transactions. This gives granular oversight over which funds move in each spend.
Seed passphrases add an extra layer via optional offsets on both supported formats. The wallet accepts 16-word Polyseed for modern recovery and the legacy 25-word Monero seed with the same offset capability, so users can restore wallets created in other clients without format conversion.
OpenAlias resolution is built in, allowing users to send to human-readable domains instead of raw addresses. The implementation follows the standard Monero protocol so any OpenAlias record works without additional configuration.
Multi-wallet support lets the app hold several independent wallets on one device, while multi-account functionality within each wallet keeps separate account indexes isolated. Switching between them requires no re-sync or external tools.
Custom node selection appears in the connection settings, where users can enter any Monero daemon address and port. The wallet then routes all traffic through the chosen node instead of defaults, giving control over sync source and potential privacy routing choices.
On 2026-10-16, a community test measured full-chain sync times across five runs on identical hardware. Monfluo completed the task in 2 minutes 16 seconds, placing third behind Monerujo at 1 minute 39 seconds and Cake at 1 minute 59 seconds.
These results reflect differences in architecture. Monfluo, as a minimal fork focused solely on Monero, performs a complete node scan without multi-coin overhead. Monerujo and Cake, with broader feature sets, achieve faster times through optimizations that Monfluo deliberately omits to reduce its codebase.
| Wallet | Sync Time (2026-10-16 test) | Key Features | Attack Surface Notes |
|---|---|---|---|
| Monfluo | 2 min 16 sec | Monero-only, coin control, Polyseed support, custom node, multi-wallet/accounts, seed offsets, no exchange rates or swaps | Smallest surface: no other assets, minimal exported components, clean F-Droid/onion path |
| Monerujo | 1 min 39 sec | Monero focus with some integrations, broader node options | Larger than Monfluo due to additional libraries and export surfaces |
| Cake | 1 min 59 sec | Multi-coin support, built-in swaps and fiat options | Widest surface from multi-asset code and third-party integrations |
Traders seeking the narrowest Monero-only experience accept the modest speed trade-off for reduced code exposure. The test used the same phone model and network conditions, isolating wallet differences rather than hardware variance.
Monfluo’s custom node option and F-Droid paths reduce some attack surface but leave clear network-level exposures that Monero’s transaction privacy features cannot hide. Connecting to a clearnet node during sync reveals the user’s IP address to the node operator and any observer on that path.
Sync times averaging two minutes and sixteen seconds mean sustained outbound connections that can be fingerprinted by ISPs or local network monitors. The wallet’s ability to select a custom node helps only if the node itself is reached over Tor or an onion service; otherwise the IP leak remains.
Funding the wallet introduces another weak point. Any XMR obtained through a KYC exchange ties the on-chain balance to an identity, regardless of later coin-control or seed-passphrase use inside Monfluo. Users who install via the clearnet fdroid.monfluo.org address also expose their IP at download time.
Practical steps include fetching the APK exclusively from the onion mirror, configuring a trusted onion node inside the wallet, and routing all traffic through Tor or a VPN before the first sync. Avoiding KYC on-ramps and keeping the device de-Googled further limits metadata correlation. These measures do not make activity untraceable; they simply reduce the number of obvious leaks at the network and distribution layers.
Download the APK directly from the Codeberg releases or add the dedicated F-Droid repository at fdroid.monfluo.org or its onion mirror. The clean installation path works well on de-Googled devices like GrapheneOS.
Monfluo accepts 16-word Polyseed or 25-word seeds, with optional seed passphrases or offsets for added protection.
Yes, the wallet lets you choose a custom Monero node instead of relying on defaults.
Add the repository URL through F-Droid’s official process and check the repository’s signing key against the project’s Codeberg page before installing.
Reviews from October 2026 highlight Monfluo’s minimal attack surface and onion/F-Droid install options as suitable for GrapheneOS users seeking a focused Monero wallet.
No, it operates as a standalone non-custodial wallet with no built-in exchange rates, swaps, or fiat services.
