The first iteration of account abstraction from Dynamic uses ZeroDev and embedded wallets.

This guide will walk you through setting up ZeroDev and Dynamic so that you can sponsor transactions. While we’re using Base Sepolia for this guide, you can use any network that has implemented the Ethereum Petra upgrade.

​
Initial setup

1

ZeroDev Account

Sign up for a free account at https://dashboard.zerodev.app/ and create a project, configure your project name and network (we’ll use Base Sepolia for this example, but you can choose any supported network) and copy your new ZeroDev project ID.

Note that the network you select in your ZeroDev project will be the network that the smart contract wallet is deployed on and cannot be changed without creating a new project. Choose a network that aligns with your application’s needs.

2

Enable in Dynamic

In the EVM section of your Dynamic Dashboard, toggle on the network you selected in the previous step (we’re using Base Sepolia in this guide) and click Save.

Now, go to the Account Abstraction section, enable ZeroDev and paste in your ZeroDev project id.

3

Adding Multichain Providers (if desired)

You must be using at least SDK version 3.3.0 or 4.0.0-alpha.8 to have access to this feature

Click on “Add another chain”. You can input 1 ZeroDev project ID per chain you would like enabled.

If you would like to remove a multichain ZeroDev provider, hover your mouse over the network icon and you should be able to click the “Trash icon” to remove.

Click “Yes” to save and add another provider if desired.

4

Choose who gets a Smart Contract Wallet (SCW)

On the same configuration page as the step above, you’ll see there are two different types of configuration for issuing Smart Contract Wallets (SCWs) in Dynamic - the wallet level and the user level.

  • Wallet level

Choose whether to issue SCWs to all wallets, or only to embedded wallets. Note that for the former, you will need to handle the UI and frontend yourself.

  • User level

Choose whether to issue SCWs to all your users (existing included next time they log in), or just new users.

5

Choose if your users see both the signer and smart wallet

On the same configuration page as the 2 steps above, you’ll see there is a setting for how the Dynamic SDK treats the signer and the smart wallet - only the smart wallet or both the smart wallet and signer.

  • Show Smart Wallet Only

Only allows you to interact with the smart wallet directly.

  • Show Smart Wallet & Signer

Treats the smart wallet and signer as separate wallets which you can switch between.

6

Enable Dynamic-powered embedded wallets + Email

Back in your Dynamic Dashboard, go to the Embedded Wallets section and enable Dynamic-powered embedded wallets.

Lastly, in the Log in & User Profile section, enable Email sign up (optionally, enable social sign up and configure oauth)

Note that we currently only create smart wallets for embedded wallets. You will see native web3 wallets in your Dynamic widget, and can still use one to sign in, but only new embedded wallets will have a smart wallet.

7

Render Dynamic

For this guide, we’ll be using React and TypeScript, but this can easily be adapted to other frameworks. If you don’t already have an app created, check out our Quickstart guide or Create dynamic app.

In your existing project, make sure to install the account abstraction package:

Shell
npm install @dynamic-labs/ethereum-aa

Then add the ZeroDevSmartWalletConnectors to your existing walletConnectors array in the DynamicContextProvider:

To use ZeroDev v5.2, use Dynamic SDK version ^2.0.5. For newer versions, use the latest compatible Dynamic SDK.

  import { DynamicContextProvider, DynamicWidget } from "@dynamic-labs/sdk-react-core";
  import { EthereumWalletConnectors } from "@dynamic-labs/ethereum";
  import { ZeroDevSmartWalletConnectors } from "@dynamic-labs/ethereum-aa";

  const App = () => (
    <DynamicContextProvider
      settings={{
        environmentId: "YOUR_ENVIRONMENT_ID",
        walletConnectors: [
          EthereumWalletConnectors,
          ZeroDevSmartWalletConnectors
        ],
      }}
    >
      <DynamicWidget />
    </DynamicContextProvider>
  )

  export default App;

Make sure to grab your Dynamic environment id from the Dynamic Dashboard under Developer > SDK & API Keys, and replace it in the environmentID setting.

8

Set up a gas sponsorship rule

Now we will set up a basic gas sponsorship policy in the ZeroDev dashboard

In the Gas Policies tab, click on the button labeled “New” in the Project Policies section

Select “Amount” as the Type, “0.1” as the value and “Day” as the interval. This is saying that we will sponsor up to 0.1 ETH total per day

Click Create Project Policy, and that’s it! Now start your app, log in and try sending some ETH out. The Dynamic SDK will check if a transaction meets your gas policies and will automatically hide the gas in the transaction confirmation step if the gas is sponsored, if not the gas will be displayed.

Since you will be creating a brand new wallet when you log in, you will need to fund it with the native token of your chosen network. If you’re using Base Sepolia as in this guide, you can access a free ETH faucet here: https://www.alchemy.com/faucets/base-sepolia

9

Using the Kernel

To interact with the wallet, you will need to interact with the kernel client. This allows you to send user operations and transactions through your smart wallet.

const connector = primaryWallet?.connector;

const kernelClient = connector.getAccountAbstractionProvider({
  withSponsorship: true,
});

const userOpHash = await kernelClient.sendUserOperation({
  callData: await kernelClient.account.encodeCalls([
    {
      data: "0x",
      to: zeroAddress,
      value: BigInt(0),
    },
    {
      data: "0x",
      to: zeroAddress,
      value: BigInt(0),
    },
  ]),
});

Note that there is a delay between loading the page and the ZeroDev kernel client being available. To ensure that the kernel client is available, please await one of the following methods: getAddress(), getConnectedAccounts() or getNetwork() before calling getAccountAbstractionProvider().

​
Complete EIP-7702 Example

The only bundler that supports EIP-7702 is Pimlico. So you will need to use the ZeroDevSmartWalletConnectorsWithConfig connector and pass in the bundlerProvider prop with the value PIMLICO.

 ZeroDevSmartWalletConnectorsWithConfig({ bundlerProvider: 'PIMLICO' })

If you’re planning to use EIP-7702 (which allows EOAs to upgrade to smart accounts), the same kernel interaction principles apply. To learn more about EIP-7702, see our EIP-7702 guide.

import { EthereumWalletConnectors, } from '@dynamic-labs/ethereum';

          },
        ]),
      });

      const { receipt } = await kernelClient.waitForUserOperationReceipt({
        hash: userOpHash,
      });

      setTxHash(receipt.transactionHash);
      setError("");
    } catch (err: unknown) {

export default App

When using EIP-7702, make sure to:

  • Enable a 7702 compatible network (like Odyssey Testnet) on Dynamic’s Chains
  • Select 7702 for wallet options during ZeroDev configuration in the dashboard

Send a transaction

Run your app, and if you copied our snippet from earlier, you should see this basic page

Click Connect your wallet, enter your email and hit Continue. After pasting in your OTP you’ll be fully logged in!

Next, we’re going to send a transaction. To do that, we will need some of the network’s native token. Grab your wallet address by clicking on the Dynamic Widget, then click on the three dots next to your address and hit “Copy wallet address”. If you’re using Base Sepolia as in this guide, you can paste your address into the Base Sepolia Faucet which will deposit some free ETH into your account. After doing so, if you refresh your app, you should see your balance update

Optionally, set up fiat onramp by following our guide here: https://docs.dynamic.xyz/fiat-onboarding/banxa

Now, send yourself some tokens by clicking on the Send button in the Dynamic Widget. Enter 0.01 as the amount, and an address of your choosing as the recipient, then hit Send now. You will see a screen like the following. Notice that there is no gas estimate field, because this transaction will be sponsored!

Hit confirm, sign for the transaction with your passkey. Congratulations, you just sent a gas-sponsored transaction! If you take your smart wallet address and paste it into the block explorer for your network (for Base Sepolia, that’s the Base Sepolia Scan), you will see your smart wallet and the transaction you just sent.

​
Advanced Configuration

Now that you’ve completed the initial setup and sent your first transaction, you can utilize the full functionality of ZeroDev inside Dynamic - everything from session keys to gas policies. Learn more in the ZeroDev Docs.

​
Specifying a bundler/paymaster RPC

Use ZeroDevSmartWalletConnectorsWithConfig and pass in values for bundlerRpc and paymasterRpc:

import { ZeroDevSmartWalletConnectorsWithConfig } from "@dynamic-labs/ethereum-aa";

<DynamicContextProvider
  settings={{
    environmentId: "YOUR_ENV_ID",
    walletConnectors: [
      ZeroDevSmartWalletConnectorsWithConfig({
        bundlerRpc: "CUSTOM_BUNDLER_RPC",
        paymasterRpc: "CUSTOM_PAYMASTER_RPC",
      }),
    ],
  }}
>
  {/* ... your app */}
</DynamicContextProvider>;

For more info, see: Pimlico Paymaster documentation

​
Specifying a bundler

To specify a bundler, use ZeroDevSmartWalletConnectorsWithConfig and pass in a value for bundlerProvider:

import { ZeroDevSmartWalletConnectorsWithConfig } from "@dynamic-labs/ethereum-aa";

<DynamicContextProvider
  settings={{
    environmentId: "YOUR_ENV_ID",
    walletConnectors: [
      ZeroDevSmartWalletConnectorsWithConfig({ bundlerProvider: "STACKUP" }),
    ],
  }}
>
  {/* ... your app */}
</DynamicContextProvider>;

For more info, see: https://docs.zerodev.app/meta-infra/rpcs#bundler—paymaster-rpcs

​
Retrieving the Kernel Client using getAccountAbstractionProvider()

import { isZeroDevConnector } from '@dynamic-labs/ethereum-aa';

const App = () => {
  const { primaryWallet } = useDynamicContext();

  useEffect(() => {
    const { connector } = primaryWallet;

    const getKernelClient = async () => {
      if (!isZeroDevConnector(connector)) {
        return;
      }

      // ensure that the kernel client has been loaded successfully
      await connector.getNetwork();

      const params = {
        // if you have gas sponsorship enabled, set `withSponsorship` to `true`, else omit
        withSponsorship: true
      };
      const kernelClient = connector.getAccountAbstractionProvider(params);
    }
  ...
}

​
Using with Viem & Ethers

You can use viem or ethers with account abstraction to sign messages or send sponsored transaction with no extra configuration, it also works with our wagmi integration.

​
Going Further

Once you’ve tested things out and want to deploy to a live network, you will need to do the following:

  1. Add your credit card to ZeroDev under Account Settings > Billing
  2. Create a new ZeroDev project and select a live network
  3. Copy your new ZeroDev project id and paste it into your Dynamic Dashboard a. We recommend using your Dynamic Sandbox environment for testing your testnet setup, and using your Dynamic Live environment for production.

​
Restricting Access to your ZeroDev Project

In order to restrict access to your ZeroDev project id to allow only dynamic to use it you can add dynamic’s static IP address’s to your projects IP allowlist.

Dynamic’s IP addresses:

  • 52.204.85.87
  • 54.145.74.8
  • 107.20.170.238
  • 52.206.26.56
  • 3.232.2.67
  • 44.213.187.169

​
Examples

​
Get smart wallet address vs signer address

The wallet connector will return your smart wallet address, that address will be used in the Dynamic UI and is the main address you will interact with. But you can fetch the signer address by using the wallet connector’s eoaConnector property and then fetching the address there.

import { useEffect, useState } from "react";
import {
  useDynamicContext,
  DynamicContextProvider,
  DynamicWidget,
} from "@dynamic-labs/sdk-react-core";
import {
  isZeroDevConnector,
  ZeroDevSmartWalletConnectors,
} from "@dynamic-labs/ethereum-aa";
import { EthereumWalletConnectors } from "@dynamic-labs/ethereum";

const SignerAddress = () => {
  const { primaryWallet } = useDynamicContext();
  const [signerAddress, setSignerAddress] = useState("");

  useEffect(() => {
    if (!primaryWallet) {
      return;
    }

    const {
      connector,
       address, // This is your smart wallet address
    } = primaryWallet;

    if (!isZeroDevConnector(connector)) {
      return;
    }

    const signerConnector = connector.eoaConnector;

    if (!signerConnector) {
      return;
    }

    const getAddress = async () => {
      const address = await signerConnector.getAddress();

      if (!address) {
        return;
      }

      setSignerAddress(address);
    };
    getAddress();
  }, [primaryWallet]);

  return <span>My Signer address: {signerAddress}</span>;
};

const App = () => (
  <DynamicContextProvider
    settings={{
      environmentId: "YOUR_ENVIRONMENT_ID",
      walletConnectors: [
        EthereumWalletConnectors,
        ZeroDevSmartWalletConnectors,
      ],
    }}
  >
    <DynamicWidget />

    <SignerAddress />
  </DynamicContextProvider>
);

export default App;
