Configure smart wallets in the dashboard ​
To get started with smart wallets, navigate to the Smart wallet tab under the Embedded wallets page on the Privy Dashboard to configure your setups.
1. Enable smart wallets ​
First, enable the smart wallets toggle and select a smart wallet type. Privy currently supports Kernel, Biconomy, Light Account, Safe, and the Coinbase Smart Wallet as smart wallet types.
INFO
If you modify your smart wallet type after users have already created smart wallets, Privy will provision the original smart wallet type for existing users to ensure they can access the accounts they already use.
2. Configure the supported networks ​
Next, configure the networks for your smart wallets. You should do this for any network that your app plans to use smart wallets on.
INFO
Need smart wallet support on a network you don't see in the Dashboard? Reach out to get set up!
For each configured network, you can optionally provide a bundler URL and/or a paymaster URL.
Bundler ​
The bundler URL specifies the node you want to use bundle operations from multiple users into a single transaction. If a bundler URL is not set for a network, Privy defaults to Pimlico's public bundler (https://public.pimlico.io/v2/{chainId}/rpc).
TIP
We strongly recommend setting your own bundler URL when taking smart wallets to production, to give you more control over bundler rate limits. Privy's default bundler is heavily rate limited and is not suitable for production usage.
Paymaster ​
The paymaster URL specifies the paymaster used to sponsor gas fees for the smart wallets on the network. If a paymaster URL is set, Privy will use that paymaster to sponsor gas fees for your users' transactions. If a paymaster URL is not set, your users' smart wallets must have a balance of the network's native currency to pay for gas fees for transactions.
For additional security, we strongly recommend setting Allowed domains for your paymaster and/or bundler through your provider's dashboard, to restrict usage of these URLs to only your website.
Recommended providers ​
If you are looking to set up a paymaster or bundler for your app, we suggest the following providers:
| Provider | Get started |
|---|---|
| Pimlico | https://dashboard.pimlico.io |
| ZeroDev | https://dashboard.zerodev.app/ |
| Alchemy | https://dashboard.alchemy.com/ |
| Biconomy | https://dashboard.biconomy.io/ |
| Coinbase | https://www.coinbase.com/developer-platform/products/paymaster |
TIP
If using ZeroDev for your paymaster or bundler, please append ?provider=PIMLICO or ?provider=THIRDWEB as a query param to your URLs to configure the provider to be Pimlico or Thirdweb (e.g. https://rpc.zerodev.app/api/v2/paymaster/yourApiKey?provider=PIMLICO).
TIP
If using Alchemy for your paymaster, please provide your Alchemy gas policy ID. Each gas policy ID is tied to a specific chain and Alchemy project.
TIP
If using Biconomy as a paymaster with @privy-io/react-auth, you can override our default paymaster context in the SmartAccountsProvider. View more in our setup notes.
Custom chains ​
If you do not see the chain you wish to configure on the drop down, you can configure a custom chain. Before configuring a custom chain on the Privy dashboard, please ensure the chain is supported by your smart wallet provider. Custom chain configuration requires an EIP155 chain ID, chain name, paymaster URL, bundler URL, and RPC URL; none of these values can be defaulted as they are in supported chains.
