No matter how your user signs up, whether it’s through social login such as Telegram, email or phone, or a branded wallet like MetaMask, you can create an embedded wallet for them using Dynamic. Simply choose when you want the wallet to be created and follow the guides below.
Please make sure you are on v4.20.6 before continuing.

​
During Signup (Automatic)

​
Creating Embedded Wallets

By default, embedded wallets are created automatically for users during sign-up if they don’t already have a wallet on the enabled chain. All you have to do is check that the “Create on Sign up” toggle is turned on in the Embedded Wallet configuration page.
Automatic embedded wallet creation only creates a single wallet for a user on each chain you have selected. For information on how to create multiple wallets, see the “Creating Wallets Any Time” section below.

​
Creating Wallets for users with External Wallets

You can automatically create embedded wallets for users who sign in with external wallets like MetaMask. To enable this feature, open the “Create on Sign Up” card, expand the “Advanced Options” panel, and turn on the “Embedded Wallet for Third-Party Wallets” toggle.

​
Custom Logic (Manual)

​
Check if User has an Embedded Wallet

You can check if a user has an embedded wallet by using the useDynamicWaas hook.

const { userHasEmbeddedWallet } = useDynamicWaas();

if (userHasEmbeddedWallet) {
  console.log('User has an embedded wallet');
}

​
Creating Wallets Any Time

If you do not want to create wallets for users automatically when they sign up, you can create wallets for users using custom logic.
To do so, call the createWalletAccount method from the useDynamicWaas hook when you want to create a wallet for a user.
You can control which chains you create wallets on by passing an array of chains to the createWalletAccount method. See the useDynamicWaas documentation for more details.
import { useDynamicWaas, useUserWallets } from "@dynamic-labs/sdk-react-core";
import { ChainEnum } from "@dynamic-labs/sdk-api-core";
// component declaration and all other logic you might need

const { createWalletAccount, getWaasWallets } = useDynamicWaas();

const onCreateWalletHandler = async () => {
  try {
    const waasWallets = await getWaasWallets();
    if (waasWallets.length === 0) {
        await createWalletAccount([ChainEnum.Evm, ChainEnum.Sol]);
    }
  } catch (e) {
    console.error(e);
  }
};
