Stack Wallet
Cypher Stack
Stack Wallet is an open-source, self-custody wallet developed by Cypher Stack, available on both mobile (iOS, Android via Google Play, APK and F-Droid) and desktop (Windows, macOS, Linux). Its identity is privacy-by-default: it supports multiple cryptocurrencies, including several privacy-oriented coins, and states that it turns on by default all privacy technologies implemented in the chains it handles. Its line-up includes Monero, Bitcoin, Bitcoin Cash, Firo, Epic Cash, Litecoin, Dogecoin and others. Private keys stay entirely in the user's hands: there is no account and no KYC to use the wallet. It includes a built-in exchange via third-party providers to swap currencies inside the app; on these operations Stack Wallet charges a small fee on top of the external provider's fee. It offers custom backup and recovery, multi-wallet support per cryptocurrency, an address book, and SegWit support for Bitcoin. It is a pick for those who want a single multi-coin wallet with privacy on by default.

- Supports privacy assets (e.g. Monero, Zcash).
- Self-hostable: you can run your own instance or node.
Weaknesses

- No notable sovereignty drawback documented.
Verdict
Score 3.9/5, solid profile. In its favour: multi-coin with privacy on by default (Monero, Firo, Epic Cash and other privacy coins alongside Bitcoin, Litecoin, Dogecoin); open-source, pure self-custody, no account or KYC, on mobile and desktop. The trade-off to weigh: the built-in exchange charges a small Stack Wallet fee on top of the third-party provider's, so it is not the cheapest way to swap; no support for smart-contract/EVM chains (no Ethereum, dApps or WalletConnect).
On the Sovereignty lens the score is 4.9/5 (outstanding): the strength is fund control (5.0/5), while censorship resistance (4.8/5) is the weak link.
