Hardware wallets
Your keys stay in the device. Kyro is the screen, the decoder and the second pair of eyes, on 33 blockchains.
One-click connect
On Ledger, every supported chain is ticked. One Connect opens each app in turn, reads the keys and skips an app that is missing or refused. You get a short result per chain: Added, Not installed or Skipped.
Per chain
Generated from the same list as the rest of the site. Monero, Polkadot and Kaspa: no hardware wallet support.

What Kyro adds
The device protects the keys and the final confirmation. Kyro still decodes the transaction in Rust and shows it in a native window before anything reaches the device.
Limits
Hardware support is the youngest part of Kyro. Read this before you move real money.
Kyro has run on real Ledger and Trezor devices. On a Ledger Nano X, addresses were checked on Bitcoin, Ethereum, Solana, Litecoin, XRP, NEAR and TON, with test signatures on Bitcoin, Ethereum and Solana. Chains without their app installed were not checked on a device. Start with a small amount.
When the device cannot decode a transaction, its screen shows only raw data and it protects your keys, not your consent. Kyro flags this with a hardened confirmation. Keep blind signing off until you need it.
Lido and Aave. Staking works from Ledger and Trezor on Solana and Cardano, and from Ledger on NEAR; TRON, Sui and Aptos need a recovery-phrase account.
EVM chains, Solana SPL, and TRC-20 on Ledger. Native coins elsewhere.
On NEAR, TON and Cardano, a Ledger gives a different account than the software wallet for the same phrase.
Hardware account files hold xpubs unencrypted: a privacy matter, not a funds one. Always verify a receive address on the device.
Trezor Safe 7
The Safe 7 speaks the Trezor Host Protocol. Kyro pairs with it once per installation.

Questions
Ledger devices with the current apps, and Trezor including the Trezor Safe 7. Cardano does not work on the Trezor One.
Yes. On the welcome screen choose “Use a Ledger / Trezor”. Kyro stores only public keys, and there is no vault or password to set.
Earn works with Lido and Aave. Staking works from Ledger and Trezor on Solana and Cardano, and from Ledger on NEAR; TRON, Sui and Aptos need a recovery-phrase account.
Yes on EVM chains and Solana (SPL). On a Ledger also TRON (TRC-20), TON (USD₮), Sui (USDC), Aptos, Algorand and NEAR (USDC, USDt). Stellar USDC works on Ledger and Trezor. On other chains, hardware accounts send the native coin.
The Ledger uses a different derivation path, so the same phrase gives a different account on NEAR, TON and Cardano. Kyro labels hardware accounts as such.
No. Run the Genuine check in Ledger’s app or the authenticity check in Trezor Suite. Kyro cannot detect a malicious device that signs what it displays.
Close Ledger Live, plug in, one Connect.
Including pairing a Safe 7.
