Example

Get native script hash of a simple PUB_KEY script:

TrezorConnect.cardanoGetNativeScriptHash({
    script: {
        type: CardanoNativeScriptType.PUB_KEY,
        keyHash: 'c4b9265645fde9536c0795adbcc5291767a0c61fd62448341d7e0386',
    },
    displayFormat: CardanoNativeScriptHashDisplayFormat.HIDE,
});

TrezorConnect.cardanoGetAddress({
    script: {
        type: CardanoNativeScriptType.ALL,
        scripts: [
            {
