Setup Smart Account Client

How to setup your smart account client :

import { 
    createComethPaymasterClient, 
    createSafeSmartAccount, 
    createSmartAccountClient,
    providerToSmartAccountSigner
} from "@cometh/connect-core-sdk";
import { arbitrumSepolia } from "viem/chains";
import { privateKeyToAccount } from "viem/accounts";
import { http } from "viem";

const bundlerUrl = process.env.NEXT_PUBLIC_4337_BUNDLER_URL;
const paymasterUrl = process.env.NEXT_PUBLIC_4337_PAYMASTER_URL;

const signer = await providerToSmartAccountSigner(
    window.ethereum
);

const publicClient = createPublicClient({
    chain: arbitrumSepolia,
    transport: http(),
    cacheTime: 60_000,
    batch: {
        multicall: { wait: 50 },
    },
});

const smartAccount = await createSafeSmartAccount({
    chain: arbitrumSepolia,
    publicClient,
    signer,
})

const paymasterClient = await createComethPaymasterClient({
    transport: http(paymasterUrl),
    chain: arbitrumSepolia,
    publicClient,
});

 const smartAccountClient = createSmartAccountClient({
    account: smartAccount,
    chain,
    bundlerTransport: http(bundlerUrl),
    paymaster: paymasterClient,
    userOperation: {
        estimateFeesPerGas: async () => {
            return await paymasterClient.getUserOperationGasPrice();
        },
    }
})
