/**
 * Signs a [EIP-191](https://eips.ethereum.org/EIPS/eip-191) personal sign message via [ERC-7739 `PersonalSign` format](https://eips.ethereum.org/EIPS/eip-7702).
 *
 * This Action is suitable to sign messages for Smart Accounts that implement (or conform to) [ERC-7739](https://eips.ethereum.org/EIPS/eip-7702) (e.g. Solady's [ERC1271.sol](https://github.com/Vectorized/solady/blob/main/src/accounts/ERC1271.sol)).
 *
 * - Docs: https://viem.sh/experimental/erc7739/signMessage
 *
 * With the calculated signature, you can:
 * - use [`verifyMessage`](https://viem.sh/docs/utilities/verifyMessage) to verify the signature,
 *
 * @param client - Client to use
 * @param parameters - {@link SignMessageParameters}
 * @returns The signed message. {@link SignMessageReturnType}
 *
 * @example
 * import { createWalletClient, custom } from 'viem'
 * import { mainnet } from 'viem/chains'
 * import { signMessage } from 'viem/experimental/erc7739'
 *
 * const client = createWalletClient({
 *   chain: mainnet,
 *   transport: custom(window.ethereum),
 * })
 *
 * const signature = await signMessage(client, {
 *   account: '0xE8Df82fA4E10e6A12a9Dab552bceA2acd26De9bb',
 *   message: 'hello world',
 *   verifier: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
 * })
 *
 * @example
 * // Account Hoisting
 * import { createWalletClient, custom } from 'viem'
 * import { privateKeyToAccount } from 'viem/accounts'
 * import { mainnet } from 'viem/chains'
 * import { signMessage } from 'viem/experimental/erc7739'
 *
 * const client = createWalletClient({
 *   account: '0xE8Df82fA4E10e6A12a9Dab552bceA2acd26De9bb',
 *   chain: mainnet,
 *   transport: custom(window.ethereum),
 * })
 *
 * const signature = await signMessage(client, {
 *   message: 'hello world',
 *   verifier: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
