Lobstr
Ultra Stellar
Lobstr is a self-custody wallet focused on the Stellar ecosystem and, more recently, the XRP Ledger. It is operated by Ultra Stellar (an Estonian entity, Lobstr.co OÜ), so with a legal seat in the European Union. It is available on iOS, Android and as a Chrome extension (LOBSTR Signer Extension). The company claims over 1 million users and millions of transactions per month. On custody, Lobstr states that you control your keys, and offers several security layers: 2FA, PIN code and multisig. Alongside the app there is LOBSTR Vault, a security-focused companion application (multisig) on iOS and Android. Inside the wallet you can buy, swap and manage assets on Stellar and the XRP Ledger. It is a practical pick for those living in the Stellar/XRP ecosystem who want a polished app backed by a European entity; anyone seeking EVM coverage or native Bitcoin should look elsewhere.

Strengths
- Self-custody with several security layers (2FA, PIN, multisig) and the Vault companion app for multisig; a European entity (Estonia) behind it; over 1 million users; strong for Stellar and the XRP Ledger on mobile and a Chrome extension.
- Self-custody: funds stay in your wallet — the platform cannot touch them.
- No KYC: usable without identity verification.
Weaknesses
- Covered only on Stellar and the XRP Ledger, with no EVM chains or native Bitcoin; the main app is not verifiably open-source; the built-in buy and swap features can route through third-party providers that add fees and, in some cases, their own checks.
- FATF-aligned jurisdiction: strong cooperation with authorities.
Verdict
Score 3.8/5, solid profile. In its favour: self-custody with several security layers (2FA, PIN, multisig) and the Vault companion app for multisig; a European entity (Estonia) behind it; over 1 million users; strong for Stellar and the XRP Ledger on mobile and a Chrome extension. The trade-off to weigh: covered only on Stellar and the XRP Ledger, with no EVM chains or native Bitcoin; the main app is not verifiably open-source; the built-in buy and swap features can route through third-party providers that add fees and, in some cases, their own checks.
On the Sovereignty lens the score is 3.8/5 (very strong): the strength is fund control (5.0/5), while trustless / auditability (2.5/5) is the weak link.
