# Introduction

> What Microset is, and the context for this security review.

<Info>
  This is the security and transparency documentation for Microset. It explains
  what the dApp does, how users interact with it, the on-chain program it uses,
  and its security and privacy practices. It is written to be useful to end users
  as well as wallet security teams, automated risk engines, and integration
  partners.

## What is Microset

Microset is a decentralized **prediction market** built on **Solana** using the
[Anchor](https://www.anchor-lang.com/) framework. Users stake on the outcomes of
real-world events (for example, cricket matches). It is **parimutuel**: all stakes
for a market are pooled, and when the market resolves, everyone who picked the
winning outcome shares the pool, minus a protocol fee.

</Frame>

> **Primary purpose:** A non-custodial, on-chain parimutuel prediction market —
> stake on event outcomes and settle based on real-world results.

Microset is **non-custodial**: users connect their own Solana wallet, and every
on-chain action requires a transaction the user signs themselves. The program
holds market reserves in program-derived vault accounts (PDAs) governed entirely
by on-chain rules, not by an operator who can freely move user funds.

<Note>
  **Market resolution.** Microset does not decide outcomes itself. Markets are
  resolved using **trusted third-party data APIs** (such as the Roanuz Sports API
  for cricket) — when the official data source reports a final result, that result
  drives on-chain resolution. See [Program & Contracts](/security/contracts).
