# Epoch Bundler

Epoch Bundler is Compliant with ERC-4337 Spec tests, but it also adds additional functionalities.

You can find all the default bundler RPC endpoints [here](https://github.com/eth-infinitism/bundler/blob/633fb4d8298b432a5b0fa0dc48f2265b80c3a5a5/packages/bundler/src/BundlerServer.ts#L132).

### **Additional Endpoints in Epoch's Bundler Implementation**

**eth\_sendUserOperation**

This method works as it does in a normal bundler, but also accepts some additional parameters. 

This includes `advancedUserOperation` - This includes [triggers](/use-epoch-sdk/intent-automation-module/triggers.md) and evaluation statement.

**eth\_getUserOperations**

This RPC endpoint returns a list of transactions with bundler that are supposed to be executed in the future.

It simply takes user's smart contract wallet address as a parameter and returns a list of queued Userops.

**Request**

```typescript
{
     method: "eth_getUserOperations",
     params: [
       "0xb28884540Dc4FA18568Bbc8564386eBd342e3a04"
     ],
}
```
