# Audits

AstralBeam's contracts and off-chain infrastructure undergo independent third-party security review before any mainnet deployment.

## Completed & In-Progress Audits

| Bridge Security Audit | EVM Locker contracts, Casper EthClient + TokenFactory contracts, relayer network (P2P mesh, attestation & verification logic), REST API | [Halborn](https://halborn.com) | Remediation review in progress | Link will be published upon completion |

The audit covers the full trust surface of the bridge:

* **Smart contracts** — the `MultiSigERC20Locker` (EVM) and the `EthClient` / `TokenFactory` (Casper), including upgrade paths, signature threshold enforcement, replay protection, and fee handling
* **Relayer network** — independent event verification, the M-of-N co-signing protocol, P2P transport security (mTLS), and fail-closed behavior
* **Off-chain services** — the public REST API and its data integrity guarantees

## Our Security Process

* Every finding is tracked to resolution and re-verified by the auditor before closure
* Security-relevant changes ship through the same audited pipeline — no direct-to-production changes
* The [Security Model](/security/security.md) page documents the trust assumptions and threat analysis in detail

## Responsible Disclosure

Found a vulnerability? Please report it privately to **<security@astralbeam.io>**. We ask that you do not disclose publicly until we've had the opportunity to remediate. We're grateful to researchers who help keep bridge users safe.

# 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.astralbeam.io/security/audits.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.
