About
Single Hand Studio is an independent developer and publisher creating mobile software for the Solana ecosystem. We design, build, publish and support our own apps and games for Solana Mobile.
Our catalogue covers both everyday utilities and games: Wherewhy, a private record keeper for Solana wallet activity; Solana Crystal Miner, an idle-tap mining game; and WalkinRunner, a location-based walking and running territory game currently in development.
Our apps are designed for Solana Mobile devices and connect through Mobile Wallet Adapter wallets.
Our apps never ask for your seed phrase or private keys.
Questions and bug reports for every app go to one studio support inbox, handled by the studio itself.
