Prepares a signed transaction ready for broadcasting on the Ethereum network.

Parameters:

network - The Ethereum network where the transaction is to be broadcast (e.g., Mainnet, Ropsten).

fromPrivateKey - The private key of the sender's address.

toAddress - The address to which the funds will be sent.

amount - The amount to be sent, in full units (e.g., 1.123456789012345678 ETH).

coin - The coin type being sent (e.g., ETH).

nonce - The transaction nonce.

gasPriceInETHWei - The gas price in wei (e.g., 150 wei, equivalent to 0.000000000000000150 ETH).

gasLimitInUnits - The gas limit for the transaction (e.g., 21000 units for a standard ETH transaction).

Returns:

A string representing the signed transaction ready to be broadcast.

Throws:

CryptoJDKException - if an error occurs during the signing process.
