# Security and fairness

<Info>
  WIP — This guide is being updated to reflect the latest OS workflows.
</Info>

## Overview

Ensure integrity across games, payouts, and campaign execution using cryptographic proofs and on-chain transparency.

## Randomness & Game Resolution

* Switchboard VRF for lottery and draw-based events
* Commit-reveal where appropriate (pre-committed hashes, later reveals)
* Timestamped event logs and deterministic resolution rules

## Payouts & Escrow

* PDA escrow accounts hold funds during resolution
* Merkle root distributions enable efficient claims and verification
* Public receipts with winner lists and amounts

## Safeguards & Controls

* Anti-manipulation: bet caps, rate limits, reputation scoring
* Circuit breakers for abnormal conditions and upgrades
* Multi-signature controls for sensitive operations

## Audits & Monitoring

* Independent security reviews
* Continuous monitoring and anomaly detection
* Public reporting and transparency dashboards

## Incident Response

* Triage, disclosure, remediation timelines
* Community updates and postmortems
