## What is LOBSTR

LOBSTR is a non-custodial wallet for the Stellar and XRP Ledger networks, available as iOS and Android apps and a web app. It is operated by the Estonian company Ultra Stellar OÜ, which is not affiliated with the Stellar Development Foundation. Companion products include LOBSTR Vault (multisig signer) and a browser signer extension.

## Who holds the keys

| Parameter | Details |
|---|---|
| Key control | Keys are generated on the device and transactions are signed on the device; LOBSTR cannot move funds or see the keys. |
| Account model | A LOBSTR account (passkey in the mobile apps or email-based on the web) syncs an encrypted copy of the secret key and recovery phrase through LOBSTR's server. |
| Seed phrase | A 12- or 24-word recovery phrase; LOBSTR has no access to it. |
| Recovery | Wallets created before 1 September 2020 used an older server-side key storage; migration to on-device keys was required by 10 July 2026. |

## Features and supported networks

| Parameter | Details |
|---|---|
| Platforms | iOS, Android and web; LOBSTR Vault app; Chrome signer extension. |
| Supported networks | Stellar and XRP Ledger, including stablecoins and tokenized assets on them. |
| Swaps | On-chain swaps on Stellar and the XRP Ledger, and cross-chain swaps through a NEAR Intents integration. |
| Buy / sell | Buy with card, bank transfer, Apple Pay or Google Pay through partners. |
| Multisig | LOBSTR Vault adds Stellar multisig; Vault keys stay on the device. |

## Security and audits

- Secret key and recovery phrase are encrypted client-side (xsalsa20-poly1305) with a key derived from the user's password before the encrypted copy is stored on LOBSTR's server.
- Optional 2FA, PIN or biometric lock, passkey sign-in in the mobile apps, and mandatory email confirmation for logins from new IP addresses.
- LOBSTR Vault is open source under GPL-3.0; the main LOBSTR app's source code is not listed in the company's public GitHub repositories.

## Fees

|---|---|
| Swaps | Stellar swaps: 0.5% to 1% built into the rate depending on asset category; 15% for assets flagged as scam; limit orders free. |
| Swaps | XRP Ledger swaps: 0.6% for curated assets including XRP, 1% for others. |
| Swaps | Swap fee discounts of 50% or 100% for holders of AQUA and ICE tokens in Silver or Gold loyalty tiers. |

## History

| Date | Event |
|---|---|

| 1 September 2020 | On-device key storage introduced for newly connected wallets. |

## Risks and caveats

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
