Send PrivateTransaction

Introduction

This group of RPC methods allows users to submit private transactions to the BNB chain. These methods are specifically designed to keep transactions confidential, shielding them from the standard transaction pool to prevent front-running attacks and granting exclusive benefits to members of the 48club with SoulPointMembership.

RPC Method Names and Parameters

1. eth_sendPrivateTransaction

   • Parameters:

     • signedRawTransaction (hexutil.Bytes)

2. eth_sendPrivateTransactionWith48SP

   • Parameters:

     • signedRawTransaction (hexutil.Bytes)

     • 48SoulPointMemberSignature (hexutil.Bytes)

   • Note: This method returns the hash of the transaction, similar to the regular eth_sendPrivateTransaction.

3. eth_sendBatchPrivateTransactionsWith48SP

   • Parameters:

     • listSignedRawTransaction ([]hexutil.Bytes)

     • 48SoulPointMemberSignature (hexutil.Bytes)

   • Note: Unlike the single transaction method, this method does not return individual transaction hashes; it only confirms the request was received without errors or returns an error if the submission fails.

Response Examples

Successful Transaction Submission

For a successful single transaction submission, the response includes the transaction hash:

{
  "jsonrpc": "2.0",
  "id": "1",
  "result": "0x2a5b3732b95940abb9f7102d8cd04c35db61b66836d1471a1a01e37168078bf9"  // Transaction hash
}

Error in Transaction Submission

If there is an error during submission, such as a mismatch in the required gas price, the error will detail the specific issue:

{
  "jsonrpc": "2.0",
  "id": "1",
  "error": {
    "code": -32000,
    "message": "[private transaction service] require GasPrice=%d, Provide=%d"
  }
}
