Spire interfaces seamlessly with a range of wallets including mobile, web, and desktop options such as AirGap, Kukai, and Galleon. By using Spire, you can more conveniently engage with Tezos decentralized applications (dApps). Additionally, you can connect your Ledger hardware wallet to Spire, allowing you to sign Beacon requests directly through your Ledger device, which is suggested as an option for developers. Moreover, Spire offers the ability to locally store a private key that can either be generated or imported using a mnemonic phrase. This functionality enhances security and ease of use for users engaged in the Tezos ecosystem.
