# PropAMM Bundle Submission

Proprietary AMMs (PropAMMs) let market makers stream live, signed price quotes directly to block builders, keeping on-chain pricing in step with real-time market conditions rather than relying on a passive bonding curve. This means tighter spreads and better execution for trades routed through PropAMM liquidity, compared to trading against a stale pool price.

`pamm_submit_bundle` is a dedicated endpoint for submitting bundles that route through PropAMM liquidity on BSC. It gives traders and searchers a direct path to this liquidity through bloXroute's Cloud API, with the same fast, reliable bundle delivery you get from `blxr_submit_bundle` today.

This service is available via **Cloud API** only.

## Submission Endpoint

* Method: `pamm_submit_bundle`
* Endpoint: `api.blxrbdn.com`
* Request type: *`HTTPS,WSS`*

| `reverting_tx_hashes`      | *\[Optional]* A list of transaction hashes within the bundle that are allowed to revert. Default is empty list: the whole bundle would be excluded if any transaction reverts.                    |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bloxroute.com/bsc/submit-bundles/pamm-bundle-submission.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
