const transactionHttp = new TransactionHttp(APIUrl);

const generationHash = process.env.NETWORK_GENERATION_HASH as string;

let private_key: string = "123...456";

const account = Account.createFromPrivateKey(private_key, NetworkType.TEST_NET);

const mosaicId = new MosaicId([2262289484, 3405110546]);

const modifyMetadataTransaction = ModifyMetadataTransaction.createWithMosaicId(
    NetworkType.TEST_NET,
    Deadline.create(),
    undefined,
    mosaicId,
    [new MetadataModification(MetadataModificationType.ADD, "key1", "value1")]
);

const signedTransaction = modifyMetadataTransaction.signWith(account, generationHash);

transactionHttp.announce(signedTransaction);

const transactionHttp = new TransactionHttp(APIUrl);

const generationHash = process.env.NETWORK_GENERATION_HASH;

const private_key = "123...456";

const account = Account.createFromPrivateKey(private_key, NetworkType.TEST_NET);

const mosaicId = new MosaicId([2262289484, 3405110546]);

const modifyMetadataTransaction = ModifyMetadataTransaction.createWithMosaicId(
    NetworkType.TEST_NET,
    Deadline.create(),
    undefined,
    mosaicId,
    [new MetadataModification(MetadataModificationType.ADD, "key1", "value1")]
);

const signedTransaction = modifyMetadataTransaction.signWith(account, generationHash);
