Cardano: get address

Display requested address derived by given BIP32-Ed25519 path on device and returns it to caller. User is presented with a description of the requested key and asked to confirm the export on Trezor.

const result = await TrezorConnect.cardanoGetAddress(params);

Params

**Optional common params**

Exporting single address

  • addressParametersrequired see description below
  • addressoptional string address for validation (read Handle button request section below)
  • protocolMagic - required Integer 764824073 for Mainnet, 1097911063 for Testnet
  • networkId - required Integer 1 for Mainnet, 0 for Testnet
  • showOnTrezoroptional boolean determines if address will be displayed on device. Default is set to true
  • derivationTypeoptional CardanoDerivationType enum. determines used derivation type. Default is set to ICARUS_TREZOR=2

Exporting bundle of addresses

  • bundle - Array of Objects with single address fields

Address Parameters

flowtype
  • addressType - required CardanoAddressType/number - you can use the flow CARDANO.ADDRESS_TYPE object or typescript CardanoAddressType enum. Supports all address types.
  • pathrequired string | Array<number> minimum length is 5. read more
  • stakingPathoptional string | Array<number> minimum length is 5. read more Used for base and reward address derivation
  • stakingKeyHash - optional string hex string of staking key hash. Used for base address derivation (as an alternative to stakingPath)
  • certificatePointer - optional CardanoCertificatePointer object. Must contain numbers blockIndex, txIndex and certificateIndex. (flowtype) Used for pointer address derivation. read more about pointer address
  • paymentScriptHash - optional string hex string of payment script hash.
  • stakingScriptHash - optional string hex string of staking script hash.

Handle button request

Since [email protected] there is a possibility to handle UI.ADDRESS_VALIDATION event which will be triggered once the address is displayed on the device. You can handle this event and display custom UI inside of your application.

If certain conditions are fulfilled popup will not be used at all:

  • the user gave permissions to communicate with Trezor
  • device is authenticated by pin/passphrase
  • application has TrezorConnect.on(UI.ADDRESS_VALIDATION, () => {}); listener registered
  • parameter address is set
  • parameter showOnTrezor is set to true (or not set at all)
  • application is requesting ONLY ONE(!) address

Validate address using custom UI inside of your application:

import TrezorConnect, { UI } from '@trezor/connect';

TrezorConnect.on(UI.ADDRESS_VALIDATION, data => {
    console.log('Handle button request', data.address, data.serializedPath);
    // here you can display custom UI inside of your app
});

const result = await TrezorConnect.cardanoGetAddress({
    addressParameters: {
        addressType: 8,
        path: "m/44'/1815'/0'/0/0",
    },
    protocolMagic: 764824073,
    networkId: 0,
    address: 'Ae2tdPwUPEZ5YUb8sM3eS8JqKgrRLzhiu71crfuH2MFtqaYr5ACNRdsswsZ',
});
// don't forget to hide your custom UI after you get the result!
