Bundler & Paymaster Infrastructure

The thirdweb SDK handles all the heavy lifting of bundling operations and covering gas fees with a turn-key infrastructure. The thirdweb paymaster and bundler services are stand alone and can be used with any smart account contract without using the thirdweb SDKs.

On testnets, the only requirement is to obtain a free client id to get started. Once you're ready to deploy on mainnets, you will require an active billing account. You can configure your client ID to restrict interactions only with your own contracts or with any contract.

Using a Custom Bundler

Smart accounts are free to use with your own account abstraction infrastructure. To use your own paymaster & bundler, pass the bundlerUrl the SmartWalletOptions overrides:

const config: SmartWalletOptions = {
chain,
sponsorGas: true,
overrides: {
bundlerUrl: "your-bundler-url",
},
};

Using a Custom Paymaster

You can also provide an entirely custom paymaster logic by providing a paymaster function to the SmartWalletOptions overrides.

const config: SmartWalletOptions = {
chain,
sponsorGas: true,
overrides: {
paymaster: async (userOp: UserOperation) => {
// your custom paymaster logic
return myPaymasterResultLogic(userOp);
},
},
};

Pricing & Billing

To use thirdweb's account abstraction infrastructure, you need to set up a billing account on the thirdweb dashboard Settings page.

Pricing:

  • Bundler: Transaction bundle calls (non-sponsored calls) are free to use.
  • Paymaster: 10% premium on top of network fee based on your usage.

Find more information on the different billing tiers by visiting thirdweb's pricing page.
