It’s super easy in the ledger App. Don’t listen to anyone here. Just use the official Ledger App from the AppStore. If you can figure it out from there, seriously get out of crypto.

Hint: you will NEVER leave the app. It’s absurdly easy.

Check validators and apy at stakeview.app Choose a validator. Return to your ledger and stake it at the validator of your choice. If you do it yourself and not hand over your token for some platform token your risk is minimal because I quote

Staking on Solana is considered “non-custodial” because when you delegate your SOL to a validator, you never give up control or ownership. The validator has no access to your funds, they cannot take them or prevent you from unstaking in any way.
