アグリゲートボンデッドトランザクションの連署

署名待ちのアグリゲートトランザクションに署名

前提条件

このガイドでは、あなたがアグリゲートトランザクションを受信したことを前提とします。ガイドエスクローコントラクトの作成に従って、アグリゲートトランザクションをアナウンスできます。

方法 #01: デスクトップウォレットを使用する

署名されるのを待機しているアグリゲートボンデッドトランザクションがある連署者アカウントにログインします。
ホームで “partial” タブをクリックします。トランザクションリストをクリックし、ウォレットのパスワードを入力してトランザクションに署名します。

方法 #02: SDK を使用する

1. First, check if your account has incoming aggregate transactions that have not been signed. Use the TransactionHttp repository to search all the incoming aggregate transactions pending to be signed by your account.

// replace with account address
const rawAddress = 'TAXQUT-QQNS6J-EJG7PL-C6FRVJ-2USS44-GLMVUL-PGQ';
const address = Address.createFromRawAddress(rawAddress);
const nodeUrl = 'NODE_URL';
const repositoryFactory = new RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();

const searchCriteria = {
  group: TransactionGroup.Partial,
  address,
  pageNumber: 1,
  pageSize: 100,
};
transactionHttp.search(searchCriteria).subscribe(
  (page) => console.log(page.data),
  (err) => console.error(err),
);

            System.out.println(transactions);

あなたのアカウントで連署名するトランザクションハッシュをコピーして保存します。

AggregateBondedTransaction を共同署名する関数を作成します。

View Code

const cosignAggregateBondedTransaction = (
  transaction: AggregateTransaction,
  account: Account,
): CosignatureSignedTransaction => {
  const cosignatureTransaction = CosignatureTransaction.create(transaction);
  return account.signCosignatureTransaction(cosignatureTransaction);
};

View Code

const cosignAggregateBondedTransaction = (transaction, account) => {
  const cosignatureTransaction = symbol_sdk_1.CosignatureTransaction.create(
    transaction,
  );
  return account.signCosignatureTransaction(cosignatureTransaction);
};

View Code

            BiFunction<AggregateTransaction, Account, CosignatureSignedTransaction> cosignAggregateBondedTransaction = ((transaction, account) -> CosignatureTransaction
                .create(transaction).signWith(account));

3. Define the transaction hash to cosign and the signer account. If you want to cosign a transaction involving a multisig account, you should be using the cosignatory account instead.

View Code

// replace with network type
const networkType = NetworkType.TEST_NET;
// replace with private key
const privateKey =
  '0000000000000000000000000000000000000000000000000000000000000000';
const account = Account.createFromPrivateKey(privateKey, networkType);
// replace with node endpoint
// replace with transaction hash to cosign
const transactionHash =
  '0000000000000000000000000000000000000000000000000000000000000000';

const account = symbol_sdk_1.Account.createFromPrivateKey(
  privateKey,
  networkType,
);
// replace with node endpoint
// replace with transaction hash to cosign
const transactionHash =
  '0000000000000000000000000000000000000000000000000000000000000000';

            NetworkType networkType = repositoryFactory.getNetworkType().toFuture().get();
            // replace with cosigner private key
            String privateKey = "";
            Account account = Account.createFromPrivateKey(privateKey, networkType);
            // replace with transaction hash to cosign
            String transactionHash = "";

4. Retrieve the complete transaction object from the node using the TransactionHttp repository. At this point, you might want to do some extra checks, like verifying the contents of the transaction. If everything looks ok, cosign the transaction with the signer account. Finally, announce the cosignature to network with transactionHttp.announceAggregateBondedCosignature.

View Code

const nodeUrl = 'NODE_URL';
const repositoryFactory = new RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();

transactionHttp
  .getTransaction(transactionHash, TransactionGroup.Partial)
  .pipe(
    map((transaction) =>
      cosignAggregateBondedTransaction(
        transaction as AggregateTransaction,
        account,
      ),
    ),
    mergeMap((cosignatureSignedTransaction) =>
      transactionHttp.announceAggregateBondedCosignature(
        cosignatureSignedTransaction,
      ),
    ),
  )
  .subscribe(
    (announcedTransaction) => console.log(announcedTransaction),
    (err) => console.error(err),
  );
