Choosing an infra provider

ZeroDev is compatible with any account abstraction infra provider. Check out these guides for integrating with a specific provider:

Read on to learn how to integrate with a custom provider.

Interop with Bundlers

For the most part, bundlers are perfectly interoperable between different providers. You simply specify the bundler RPC when you construct a Kernel client:

import { createKernelAccountClient } from "@zerodev/sdk";
import { http } from "viem";
 
const kernelClient = createKernelAccountClient({
  // other options...
 
  bundlerTransport: http("BUNDLER_RPC"),
});

Interop with Paymasters

If the Paymaster supports ERC-7677 paymaster methods, you can simply pass the Paymaster RPC URL to createZeroDevPaymasterClient:

import { createKernelAccountClient, createZeroDevPaymasterClient } from "@zerodev/sdk"
 
const paymasterClient = createZeroDevPaymasterClient({
  chain,
  transport: http('PAYMASTER_RPC'),
})
 
const kernelClient = createKernelAccountClient({
  // other options...
 
  paymaster: paymasterClient
})

To integrate with a paymaster which doesn't support ERC-7677, you need to implement the getPaymasterData function:

const kernelClient = createKernelAccountClient({
  // other options...
 
  paymaster: {
    getPaymasterData(userOperation) {
      // return `paymasterAndData` for `EntryPoint 0.6` or `paymaster` and `paymasterData` for `EntryPoint 0.7`
    }
  }
})
