Alby operates on a self-custodial model where users control their own private keys. Alby Hub is explicitly designed so that Alby never has access to user funds - you run your own Lightning node either self-hosted or via Alby Cloud with encrypted keys. All products are open-source, enabling community verification of the codebase across repositories.
The platform implements OAuth 2.0 for API security, GDPR-compliant data handling, and employees are bound by confidentiality agreements. Technical and organizational measures protect against data risks, with log files retained for 60 days for security and incident resolution. The browser extension secures key storage and Nostr interactions with user-controlled backups.
Alby has maintained a positive reputation in the Bitcoin and Nostr communities, with users on BitcoinTalk and app stores affirming its legitimacy for Lightning usage. No security incidents have been reported in public sources.

Bitcoin Keeper is a fully non-custodial, open-source wallet where users maintain complete control of their private keys. The company never has access to user funds and cannot sign or authorize transactions on behalf of users.
The application code is publicly available on GitHub (bithyve/bitcoin-keeper), allowing independent security review by the community. Bitcoin Keeper provides signed checksums and detached GPG signatures for APK verification, enabling users to confirm they are running authentic, unmodified software. WalletScrutiny has included Bitcoin Keeper in their build verification efforts, indicating attention to transparency.
The wallet supports connecting to your own Bitcoin node, eliminating reliance on third-party servers for transaction verification. Multi-key vault configurations distribute signing authority across multiple devices and locations, removing single points of failure. The app is Bitcoin-only, avoiding the complexity and attack surface of multi-asset wallets.

Bitcoin Jungle operates as a nonprofit, open-source community project built on the proven Bitcoin Beach/Galoy wallet codebase, which has been battle-tested in El Salvador's circular economy. The project maintains transparency through its open-source foundation, allowing anyone to audit the underlying code.
The wallet implements daily transaction limits and automated internal audits for suspicious activity to protect users. Data is encrypted in transit, and the project does not hold bank accounts, reducing counterparty risk. With over 380 merchant locations accepting Bitcoin in Costa Rica and average payments under 20,000 colones (~$35 USD), the system is designed for everyday spending rather than large-value storage.
Bitcoin Jungle is a member of the Bitcoin Association of Costa Rica and has built strong local trust since launching in late 2021, with 80% of users being Costa Rican residents. The project operates without fees or commissions, demonstrating its community-first, non-commercial mission.
