# @alchemy/smart-accounts > Overview of smart-accounts > For the complete documentation index, see [llms.txt](/docs/llms.txt). {/* This file is auto-generated by TypeDoc. Do not edit manually. */} **Beta** — This package replaces `@account-kit/smart-contracts`. This is a low-level package. Most users should use [`@alchemy/wallet-apis`](https://www.alchemy.com/docs/wallets/reference/wallet-apis) unless you need to use interface with Smart Accounts directly via viem. Viem-compatible smart account implementations for Alchemy's smart contract accounts. Supports LightAccount, Modular Account v1, and Modular Account v2 with EIP-7702. ## Installation ```bash npm install @alchemy/smart-accounts @alchemy/common viem ``` ## Example Usage ```ts import { createPublicClient } from "viem"; import { createBundlerClient, createPaymasterClient, } from "viem/account-abstraction"; import { sepolia } from "viem/chains"; import { generatePrivateKey, privateKeyToAccount } from "viem/accounts"; import { alchemyTransport } from "@alchemy/common"; import { estimateFeesPerGas } from "@alchemy/aa-infra"; import { toModularAccountV2 } from "@alchemy/smart-accounts"; const transport = alchemyTransport({ apiKey: "YOUR_API_KEY" }); // 1. Create a MAv2 smart account const account = await toModularAccountV2({ client: createPublicClient({ chain: sepolia, transport }), owner: privateKeyToAccount(generatePrivateKey()), }); // 2. Create a bundler client with the account const bundlerClient = createBundlerClient({ account, chain: sepolia, transport, userOperation: { estimateFeesPerGas, }, // Optional: sponsor gas with a paymaster paymaster: createPaymasterClient({ transport }), paymasterContext: { policyId: "YOUR_POLICY_ID" }, }); // 3. Send a user operation const hash = await bundlerClient.sendUserOperation({ calls: [{ to: "0x...", value: 0n, data: "0x" }], }); const receipt = await bundlerClient.waitForUserOperationReceipt({ hash }); ``` ## Key Exports ### LightAccount -
