We work with Bitcoin, Ethereum and EVM-compatible chains, and non-EVM networks depending on your roadmap. Multi-chain wallets are built on an abstraction layer so adding a new network later means writing an adapter rather than reworking the app. We also handle token standards, NFT display, and swap integrations.

Cryptographic and key-handling code is unit tested in isolation, transaction flows run through full testnet cycles, and we perform adversarial testing on recovery, signing, and session handling. We build so that an external security audit — which we recommend for any wallet holding real value — goes smoothly rather than turning into a rewrite.

Yes. We integrate identity verification, sanctions screening, and third-party fiat on-ramp and off-ramp providers. It's far cheaper to design for these during discovery than to retrofit them, so we raise the question early and structure onboarding and data storage accordingly.

Often, yes. We start with a technical audit covering key management, chain integrations, dependency health, and test coverage, then give you an honest assessment of what to keep and what to rebuild. From there we can stabilize the current app, ship new features, or run ongoing maintenance.

Discovery and technical architecture first, then UX/UI design, then iterative engineering sprints with working builds you can test on device. QA runs throughout, not just at the end. After release we offer support and maintenance to cover chain upgrades, SDK changes, and app store requirements.
