@ alchemy/ smart- 账户

此软件包替换 @account-kit/smart-contracts。这是一个低级软件包。 多数用户应使用 @alchemy/wallet-apis 除非您需要通过viem直接使用智能账户的接口.

与Alchemy智能合同账户的相容智能账户实施. 用 EIP-7702 支持 Light Account, Modular Account v1, 和 Modular Account v2 .

安装

npm install @alchemy/smart-accounts @alchemy/common viem

示例使用

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 });
