What LOBSTR does
LOBSTR is a non-custodial cryptocurrency wallet operating on the Stellar and XRP Ledger blockchain networks, developed by Tallinn-headquartered Ultra Stellar OÜ (with historical Paris connection). It serves primarily individual crypto users seeking to send, receive, buy, sell, swap, and track XLM, XRP, RLUSD, and other on-network assets, while also offering multisig security tooling (LOBSTR Vault) and NFC hardware signer cards (Tangem-powered) for higher-value users. The product suite spans iOS/Android mobile apps, a web wallet, a Chrome browser extension for dApp connectivity (including Soroban smart contracts), and a Merge Tool that bypasses the Stellar 1 XLM minimum balance requirement. Related wholly-owned sub-brands StellarX (an AMM/DEX) and StellarTerm (an open-source trading client) extend the platform into trading and developer tooling.
Underlying technology is built directly on the Stellar (Horizon API) and XRP Ledger decentralized networks, with users retaining custody of cryptographic keys generated and stored locally on their devices. The multi-signature Vault requires approvals from separate devices, and the Tangem-based Signer Card provides a hardware root of trust via NFC. Security is augmented through a Blockaid integration that surfaces real-time warnings on malicious addresses and assets before transaction execution. The architecture is explicitly non-custodial, with LOBSTR serving as a user interface and signing layer rather than a fund custodian.
The business model is transaction-fee driven, with no subscription pricing for end users. Revenue streams include tiered swap fees (0.5% Featured, 0.6% Curated, 0.8% Known, 1% Unknown asset listings), one-time asset listing fees ($200 Known, $2,500 Curated) and subscription-based Featured listings (3/6/12 months), Merge Tool fees (capped at 0.9 XLM), and likely revenue share from MoonPay and Mercuryo fiat on-ramp integrations. Go-to-market is product-led: the wallet is freely distributed through app stores and the web, with acquisition driven by Stellar/XRP ecosystem reach (31.6K X/Twitter followers), 4.7 average rating across 30K+ reviews, and 1M+ total users processing 10M+ monthly transactions. The company appears to be founder-led and bootstrapped, with no external funding disclosed and an 11-50 employee footprint.

LOBSTR competitors and assessment
Company assessmentDirect peers
- Xaman (XUMM): The leading XRP Ledger self-custody wallet, formerly known as XUMM. Closely comparable to LOBSTR in product positioning, chain specialization, security architecture (multisign), and user base scale. Direct head-to-head competitor in the XRP segment that LOBSTR just entered.
- Freighter: Stellar-focused browser extension wallet built for Soroban smart contract interaction. Competes directly with LOBSTR Signer Extension in the Stellar developer/dApp user segment and shares the chain-specialist positioning.
- Albedo: Web-based Stellar wallet supporting multisignature accounts, claimable balances, and Soroban transactions. Directly competes with LOBSTR for the multi-sig and dApp-connected Stellar user.
Broad incumbents
- MetaMask: The largest self-custodial multi-chain wallet, operated by ConsenSys. While it spans many ecosystems, it now supports Stellar and competes for the same wallet user. Vastly larger scale and developer ecosystem.
- Trust Wallet: Multi-chain self-custody wallet affiliated with Binance. Supports Stellar and competes in the same self-custody consumer wallet category with broader chain coverage and significantly larger user base.
- Phantom: Originally a Solana-native wallet that has expanded to multi-chain support. Comparable in product-led growth strategy, non-custodial architecture, and browser-extension-plus-mobile distribution model.
- Coinbase Wallet: Self-custody wallet from Coinbase with broad chain coverage and deep fiat on/off-ramp integration. Competes with LOBSTR for retail users wanting both a self-custody wallet and easy crypto purchase/sell flows.
- Exodus Wallet: Multi-chain desktop and mobile self-custody wallet with built-in exchange and staking. Comparable product-led growth approach and non-custodial architecture, though broader chain support than LOBSTR.
Others
- Ledger: Hardware wallet provider whose devices complement self-custody software wallets. While not a direct competitor to LOBSTR's core wallet product, it competes with LOBSTR's Vault Signer Card (Tangem) in the hardware signer category.
- Tangem: NFC hardware smart card wallet provider and LOBSTR's technology partner for the Vault Signer Card. Adjacent competitor in the hardware signer space and a key infrastructure dependency for LOBSTR's premium security tier.
