The best wallet UX starts with invisible security.

Give your users everything they expect from Web2 without giving up control of your product experience. The hardware-backed keys and real self custody that make it safe stay out of sight.

Challenges

Opinionated tools impose fake tradeoffs.

Many embedded wallets prioritize “usability” over security—while quietly retaining access to user keys, storing keys in unsafe ways, or locking developers into rigid SDKs. The result? More risks for users and tighter constraints on developers. With CubeSigner, you stay in control of your UX—and your users stay in control of their keys.

Solutions

This is how design meets execution.

Lock down keys, not your product UX.

Unlocked user experience

Skip the opinionated flows—own the full UX. From social login to 2FA to policies, our vanilla TypeScript SDK keeps things secure while you build what your product needs. Prefer plug-and-play? We’ve got prebuilt components too.

Hardware-backed signing

Provide strong protection against key compromise: your users’ keys never leave secure hardware, even when they’re signing transactions—mitigating threats like phishing and malware.

Recovery that's actually non-custodial

Provide a recovery path that doesn’t compromise your custody model. Many solutions cut corners on user custody to enable cross-device access; CubeSigner keeps you out of the chain of custody—while ensuring your users aren’t stuck if they lose their phone or forget their password.

Social Wallets: A Real-World Use Case

Tomo chose CubeSigner APIs to let their wallet users safely transact across Bitcoin, EVM, Solana, Cosmos, and more. Thanks to CubeSigner, Tomo users are protected from malicious actors and key theft while using Telegram and other dapps that embed Tomo. CubeSigner differentiates Tomo from competing wallets by keeping keys safe in secure hardware—not exposed to attackers on the web.

Case Study

“I view our collaboration with Cubist as the next great step in the evolution of Tomo as the all-in-one social wallet and social login provider. There are a lot of embedded wallet solutions that offer great UX but at the expense of user security, and that’s not something Tomo is willing to compromise on. To us, CubeSigner’s security model is key to safely unlocking functionality everywhere.”
