Cardano: get public key

Retrieves BIP32-Ed25519 extended public derived by given BIP32-Ed25519 path. User is presented with a description of the requested key and asked to confirm the export on Trezor.

ES6

const result = await TrezorConnect.cardanoGetPublicKey(params);

CommonJS

TrezorConnect.cardanoGetPublicKey(params).then(function(result) {

});

Params

Optional common params

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

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
    ]
});

Result

Result with only one public key

{
    success: true,
    payload: {
        path: Array<number>, // hardended path
        serializedPath: string,
        publicKey: string,
        node: HDPubNode,
        rootHDPassphrase: string,
    }
}

Result with bundle of publick keys

{
    success: true,
    payload: [
        { path: Array<number>, serializedPath: string, publicKey: string, node: HDPubNode, hdPassphrase: string }, // account 1
        { path: Array<number>, serializedPath: string, publicKey: string, node: HDPubNode, rootHDPassphrase: string }, // account 2
        { path: Array<number>, serializedPath: string, publicKey: string, node: HDPubNode, hdPassphrase: string }  // account 3
    ]
}

Error

{
    success: false,
    payload: {
        error: string // error message
    }
}
