/**
* Prepares an [EIP-7702 Authorization](https://eips.ethereum.org/EIPS/eip-7702) object for signing.
* This Action will fill the required fields of the Authorization object if they are not provided (e.g. `nonce` and `chainId`).
*
* With the prepared Authorization object, you can use [`signAuthorization`](https://viem.sh/docs/eip7702/signAuthorization) to sign over the Authorization object.
*
* @param client - Client to use
* @param parameters - {@link PrepareAuthorizationParameters}
* @returns The prepared Authorization object. {@link PrepareAuthorizationReturnType}
*
* @example
* import { createClient, http } from 'viem'
* import { privateKeyToAccount } from 'viem/accounts'
* import { mainnet } from 'viem/chains'
* import { prepareAuthorization } from 'viem/experimental'
*
* const client = createClient({
* chain: mainnet,
* transport: http(),
* })
* const authorization = await prepareAuthorization(client, {
* account: privateKeyToAccount('0x..'),
* contractAddress: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
* })
*
* @example
* // Account Hoisting
* import { createClient, http } from 'viem'
* import { privateKeyToAccount } from 'viem/accounts'
* import { mainnet } from 'viem/chains'
* import { prepareAuthorization } from 'viem/experimental'
*
* const client = createClient({
* account: privateKeyToAccount('0x…'),
* chain: mainnet,
* transport: http(),
* })
* const authorization = await prepareAuthorization(client, {
* contractAddress: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
