Enable Account Abstraction | Conduit Documentation

Conduit Account Abstraction simplifies the experience for your users by sponsoring their transactions, saving them gas. This guide will help rollup owners to set up the Conduit Bundler and Paymaster for your rollup.

Install the Conduit Bundler

For more details about the Conduit Bundler, visit here.

Select a Rollup

Choose the rollup where you want to install the Conduit Bundler.

Set up Billing

Enter your billing details and subscribe to the Bundler plan. For pricing details, check out Pricing & Costs.

Install ZeroDev

After installing the Conduit Bundler, you’ll be prompted to install ZeroDev. This is required to set up the Paymaster and create a gas sponsorship policy. If you’re deploying to a mainnet, you’ll also need to connect your wallet and transfer tokens to fund the deployment.

For more information about ZeroDev, check out the documentation here.
