Transaction

Generating Signed Transaction

You can use Tronweb to complete the tasks of this section, for more details, please refer to: Tronweb Github Tronweb API 文档​

Alternatively, you can use API Signature and Broadcast Flow to generate a signed transaction.

The above document shows the complete workflow of using APIs, Here is mainly Tronweb, using freezeBalance as an example.

Creating a Transaction

Create an unsigned transaction for freezing balance. Tronweb freezeBalance​

Signing the Transaction

Sign the transaction with your private key. Tronweb sign​

❗️

Never use this in any web / user-facing applications, as it will expose your private key. For security reasons, please use a local full node.

Broadcast the Transaction

Broadcast the signed transaction. Tronweb Broadcast transaction​

📘

The broadcasting function in Tronweb is sendrawtransaction without a 'broadcast' keyword, refer to the source code for details.

Full Code Example

JavaScript

const CryptoUtils = require("@tronscan/client/src/utils/crypto");const TransactionUtils = require("@tronscan/client/src/utils/transactionBuilder");​function transferContractTx() {    const privateKey = "b815adfd6ef133d5a878869cb3a2b31f32d4c1481132a71300c3e125be0ab1a1";    const token = "TRX";    const fromAddress = CryptoUtils.pkToAddress(privateKey);    const toAddress = "TQ6pM81JDC2GhrUoNYtZGvPc7SvyqcemEu";    const amount = 1;​    let transaction = TransactionUtils.buildTransferTransaction(token, fromAddress, toAddress, amount);​    let signedTransaction = CryptoUtils.signTransaction(privateKey, transaction);}

Transaction Confirmation

The mechanism of TRON's block validation is that a block is validated after this block is produced and 19 different SRs produce subsequent blocks based on this block.

When a block is confirmed, transactions inside are all confirmed. TRON provides the /walletsolidty/ interface to make it easier for users to search for confirmed transactions; the following describes how to confirm different types of transactions.

Multi-type transactions

There are many types of transactions in TRON network: protobuf TRONWEB.TRANSACTIONBUILDER Please read these contents for more details.
