/**
* Creates, signs, and sends a new transaction to the network.
* This function also allows you to sponsor this transaction if sender is a smartAccount
*
* - Docs: https://viem.sh/docs/actions/wallet/sendTransaction.html
* - Examples: https://stackblitz.com/github/wagmi-dev/viem/tree/main/examples/transactions/sending-transactions
* - JSON-RPC Methods:
* - JSON-RPC Accounts: [`eth_sendTransaction`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_sendtransaction)
* - Local Accounts: [`eth_sendRawTransaction`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_sendrawtransaction)
*
* @param client - Client to use
* @param parameters - {@link SendTransactionParameters}
* @returns The [Transaction](https://viem.sh/docs/glossary/terms.html#transaction) hash.
*
* @example
* import { createWalletClient, custom } from 'viem'
* import { mainnet } from 'viem/chains'
* import { sendTransaction } from 'viem/wallet'
*
* const client = createWalletClient({
* chain: mainnet,
