# Introduction

**ATFi (Attendance Tokenized for Incentives)** is the **Commitment Layer for Base**.

We provide the infrastructure for developers to build applications that require **verifiable commitment** and **incentivized participation**. Whether you are building an event platform, a habit-tracking app, or a high-stakes gaming tournament, ATFi provides the smart contracts and SDKs to manage stakes, yields, and settlements.

## Why ATFi?

Traditional commitment models are broken. "Free" RSVPs lead to 30-50% no-show rates. Paid tickets create friction.

ATFi introduces a third way: **Yield-Bearing Commitments**. Users stake assets (e.g., USDC) to commit. The protocol deposits these assets into DeFi yield sources (like Morpho Blue) to generate interest.

* **If they show up:** They get their principal + yield.
* **If they don't:** They lose part of their stake to the attendees.

## The Toolkit

ATFi is more than just a smart contract. It is a complete developer toolkit:

* [**Factory Contract**](/atfi-tooling-docs/smart-contracts/overview.md)**:** Deploy standardized, secure commitment vaults in seconds.
* [**Vault Implementation**](/atfi-tooling-docs/core-concepts/vaults.md)**:** Robust logic for staking, verification, and settlement.
* [**TypeScript SDK**](/atfi-tooling-docs/sdk-reference/getting-started.md)**:** A powerful library to integrate ATFi into any React/Node.js app.
* **\[Subgraph / Indexer]:** Real-time data querying (Coming Soon).
