No custodial key storage and publicly reviewable code are built to let users verify Thanos Wallet’s security model instead of taking it on faith.
LONDON, UK – July 14, 2026 – Thanos Wallet, the multi-chain wallet built for the Lithosphere ecosystem, today reiterated the two claims at the center of its security model: private keys and recovery data never leave the user’s control, and the code responsible for generating, storing, and recovering those keys is open source and available for independent review. Neither claim is unusual to state in this industry — what matters is whether a wallet is built so those claims can actually be checked rather than simply asserted.
In a self-custodial design, Thanos Wallet itself never holds a copy of a user’s private key or recovery phrase at any point — key generation, encryption, and storage all happen on the user’s own device. That removes Thanos Wallet as a party capable of accessing or freezing funds, but it also means the responsibility for safeguarding the recovery phrase sits entirely with the user, which is why the wallet’s design treats backup and recovery flows as seriously as it treats the initial setup.
“Self-custody only means something if it’s verifiable,” said J. King Kasr, Chief Scientist at KaJ Labs. “Saying a wallet never holds your keys is easy. Publishing the code that proves it, so anyone can check how keys are generated and stored, is the part that actually earns trust.”
That verifiability matters more as the wallet’s asset coverage grows. Thanos Wallet manages LITHO, wLITHO, and FGPT alongside Bitcoin, Ethereum, and EVM-based assets under a single recovery phrase, and is positioned as the primary access point for users preparing to participate in the LITHO Token Generation Event through Ignite. A wider range of assets under one wallet raises the stakes of that wallet’s security model being sound, which is the reasoning behind keeping the underlying code open to scrutiny rather than closed.
Available across web, desktop, iOS, Android, and a browser extension, Thanos Wallet is continuing to extend this self-custody, open-source approach as it adds support for additional assets and networks within the Lithosphere ecosystem.
