Why Work with Us

We are a team of experienced builders in the blockchain and crypto industry. Our journey began from users seeking an easy, seamless path to accessing the crypto ecosystem. This passion fueled our exponential growth, allowing us to onboard over 15M+ active users in just over three years, with our user base growing weekly.

Our dedication to a secure and seamless user experience has made us the leading wallet on Solana, and our multi-chain approach enhances our platform's versatility, meeting the needs of a diverse and growing user base. By staying at the forefront of technology and user expectations, we continue to innovate and set industry standards for self-custodial crypto wallets.

There has never been a better time to work in crypto to help shape the future of innovation with a focus around the wallet experience!

• First impressions matter: Wallets are responsible for a user's first impression with crypto and onboarding new users into crypto. By ensuring that a user has a great first-time experience with crypto, we can help supercharge the growth of the entire ecosystem.
• Make crypto easier to navigate: There is no easy way for a user to discover and navigate all that crypto has to offer. Wallets have a unique opportunity to help users not only onboard to crypto but also stay retained by exploring new things to do.
• We live in a multi-chain world: We currently support Solana, Ethereum, Polygon, and Bitcoin with more networks to come in the near future. We are focused on creating a unified, multi-chain crypto experience for users.
