Params

Optional common params

CardanoGetPublicKey type

Exporting single public key

  • path — required string | Array<number> minimum length is 3. read more
  • showOnTrezor — optional boolean determines if publick key will be displayed on device. Default is set to true
  • derivationType — optional CardanoDerivationType enum. determines used derivation type. Default is set to ICARUS_TREZOR=2
  • suppressBackupWarning - optional boolean By default, this method will emit an event to show a warning if the wallet does not have a backup. This option suppresses the message.

Exporting bundle of publick keys

  • bundle - Array of Objects with path and showOnTrezor fields

Example

Display public key of first cardano account:

TrezorConnect.cardanoGetPublicKey({
    path: "m/44'/1815'/0'",
});

Return a bundle of cardano public keys without displaying them on device:

TrezorConnect.cardanoGetPublicKey({
    bundle: [
        { path: "m/44'/1815'/0'", showOnTrezor: false }, // account 1
        { path: "m/44'/1815'/1'", showOnTrezor: false }, // account 2
        { path: "m/44'/1815'/2'", showOnTrezor: false }, // account 3
    ],
});
