Getting a Viem WalletClient

Viem is one of the most popular libraries for interacting with EVM blockchains.

A WalletClient is an interface to interact with EVM accounts and provides the ability to retrieve accounts, execute transactions, sign messages, etc.

We provide a helper method to allow you to create a Viem WalletClient for a given wallet account.

Usage

JavaScript

import { createWalletClientForWalletAccount } from '@dynamic-labs-sdk/evm/viem';

const sendTransaction = async (walletAccount, transaction) => {
  const walletClient = await createWalletClientForWalletAccount({
    walletAccount,
  });

  const result = await walletClient.sendTransaction(transaction);
  console.log('Transaction sent:', result);

  // ...
};

React

Use useGetWalletAccounts to reactively get the wallet, then call createWalletClientForWalletAccount inside an event handler:

import { createWalletClientForWalletAccount } from '@dynamic-labs-sdk/evm/viem';
import { useGetWalletAccounts } from '@dynamic-labs-sdk/react-hooks';

function SendTransactionButton({ transaction }) {
  const { data: walletAccounts = [] } = useGetWalletAccounts();
  const walletAccount = walletAccounts[0];

  const handleSend = async () => {
    if (!walletAccount) return;

    const walletClient = await createWalletClientForWalletAccount({ walletAccount });
    const result = await walletClient.sendTransaction(transaction);
    console.log('Transaction sent:', result);
  };

  return (
    <button onClick={handleSend} disabled={!walletAccount}>
      Send Transaction
    </button>
  );
}

Viem / wagmi version compatibility

The JavaScript SDK’s EVM extension (@dynamic-labs-sdk/evm) uses viem internally. If you also use wagmi in your project, ensure your versions are compatible:

Dependency	Required range	Notes
viem	^2.45.3	viem v2.45.3+
wagmi	^2.14.11	If using wagmi alongside the SDK
@wagmi/core	^2.6.4	Installed automatically with wagmi

wagmi v3.x may work (v3.1.0 has been tested), but is outside the declared peer dependency range. Full v3 support is planned for a future release. For the React SDK wagmi connector setup, see Using Wagmi.
