Why Work with Us 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 future. We are focused on creating a unified, multi‑chain crypto experience for users.
