A hardware wallet
has a place here.
Using a Ledger account through a compatible wallet? The new Using Ledger? controls explain the setup and let you enable compatibility mode. Connect through your existing wallet, unlock the device and open its Solana app.
Referrals, Inner Rooms and House Object ownership checks can use an offline signed proof. That proof is never submitted to the network and does not charge a fee. Actual mints, trades and transfers retain their normal costs.
Ledger compatibility is new and needs more testing across wallets and devices. If anything feels awkward or fails to connect or sign, let us know which wallet and device you use and what happened. Your feedback will help us polish the flow.
