Why Work with Us Opportunity 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. We’ve acquired millions of users in our 2+ years and are adding more every week. We are by far the leading wallet on Solana, and have recently expanded onto other chains including Ethereum.

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.
