Why Work with Us


We are a team of experienced builders with a ton of traction in a big and growing market – our users are so passionate they were hacking their way into our private beta. Only months after launching we've acquired millions of users, and are adding hundreds of thousands every week. We are by far the leading wallet on Solana, and plan to expand to other chains soon.

On top of that, there has never been a better time to work in crypto and on wallets in particular.

  • Wallets play a pivotal role: Wallets are responsible for on-boarding new users into crypto, and can make or break the user experience.
  • We are moving to a multi-chain world: New blockchains and scaling solutions are coming online and gaining traction, but are lacking decent wallets and bridges.
  • DeFi & NFTs are exploding : Interest in DeFi and NFTs has exploded, yet they are still an after-thought in existing wallets.


  • Competitive salary and equity.
  • Comprehensive insurance (medical/dental/vision) — 100% covered.
  • Stipend for your ideal remote / WFH set-up: laptop, headphones, and any other work gear you may need.
  • Flexible hours and a long-standing, supportive remote environment.
  • Unlimited vacation: Take time when you need it (and we really mean it).
  • 401(k) retirement plan (although we are not matching at this time)
  • Wellness benefit
  • Daily lunch benefit

The target base salary for this role will range between $160,000 to $210,000 with the addition of equity and benefits. This is determined by a few factors including your skillset, prior relevant experience, quality of interviews and market factors (such as location) at the point in time of offer.
