To create the transaction with wallet

ETH Transaction

1. Build ETH Transaction

To create an Ethereum transaction, use the ETHTransactionRequest with the following attributes:

• create a new Build ETHTransactionRequest should include the following attributes:

  • chainID : Chain ID (e.g., Ethereum is 1).

  • toAddress : Recipient's wallet address.

  • amount : Amount to transfer.

  • gasPrice : Gas price per unit.

  • gasLimit : Maximum gas allowed for the transaction.

  • nonce : Transaction count for the sender's account.

  • data : Optional additional data for the transaction.

  • paillierGroupID : User's Paillier group ID.

  • keyGenGroupID : the keygen Group ID of master wallet

  • keyIdentity : the keyIdentity of wallet

  • ecType: Cryptographic algorithm type (e.g., eddsa, ecdsa)

Example:

    val rawTxBytes = BuildETHTransactionRequest(
        chainID = "1",
        toAddress = "0xRecipientAddress",
        amount = "10000",
        gasPrice = "20000000000",
        gasLimit = "21000",
        nonce = "0",
        data = null,
        paillierGroupID = "paillierGroupID",
        keyGenGroupID = "keyGenGroupID",
        keyIdentity = "walletKeyIdentity",
        ecType = "ecdsa"
    )
    val rawTransaction = client.buildETHTransaction(rawTxBytes)

2. Send ETH Transaction with Web3

Example:

    val web3j = Web3j.build(HttpService("https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID"))
    val transactionResponse = web3j.ethSendRawTransaction(rawTxBytes).send()

    // Build the XRP transaction
    val rawTxFlow = buildXrpTransaction(
        paillierGroupId = paillierGroupID,

    val rawTransactionBytes = rawTxFlow.first()
    println("Raw XRP Transaction Bytes: $rawTransactionBytes")
}
