Transaction

Generating Signed Transaction

You can use Visionweb to complete the tasks of this section, for more details, please refer to: Visionweb Github

Here is mainly Visionweb, using freezeBalance as an example.

Creating a Transaction

Create an unsigned transaction for freezing balance. Visionweb freezeBalance

Signing the Transaction

Sign the transaction with your private key. Visionweb 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. Visionweb Broadcast transaction

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

Transaction Confirmation

The mechanism of VISION's block validation is that a block is validated after this block is produced and 12 different FVs produce subsequent blocks based on this block.

When a block is confirmed, transactions inside are all confirmed. Vision 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.

Transaction Type	Method of transaction confirmation
transferContract and transferAssetContract	As long as the transaction can query the results via walletsolidity/gettransactioninfobyid or walletsolidity/gettransactionbyid.
TriggerSmartContract	There are two ways to judge: 1. Find transactionInfo.receipt.result=success via the /walletsolidity/gettransactioninfobyid interface (It is not recommended to use transactionInfo.result to judge, because for the http interface, successful transactions do not return this field by default). 2. Via /walletsolidity/gettransactionbyid The interface found transaction.ret.contractRet =success
InternalTransaction	Query by /walletsolidity/gettransactioninfobyid. Http interface: For successful transactions, the rejected field is not returned by default. For failed transactions, rejected=true. Grpc interface: For successful transactions, rejected=false (indicating that the current internalTransaction has not been discarded), For failed transactions, rejected=true
