If your app uses embedded wallets, you can configure Privy to create wallets automatically for your users as part of their login flow.
  • Ethereum
  • Solana
To configure Privy to automatically create embedded wallets for your user when they login, set the config.embedded.solana.createOnLogin property of your PrivyProvider:
<PrivyProvider
    appId="your-privy-app-id"
    config={{
        embedded: {
            ethereum: {
                createOnLogin: 'users-without-wallets',
            },
        },
    }}
>
    {children}
</PrivyProvider>
​
createOnLogin
'all-users' | 'users-without-wallets' | 'off'
default:"off"
Determines when to create a wallet for the user.
  • 'all-users': Create a wallet for all users on login.
  • 'users-without-wallets': Create a wallet for users who do not have a wallet on login.
  • 'off': Do not create a wallet on login.
