## About the Contest

**Tact Smart Battle** is a global smart contract competition organized by [TON Studio](https://tonstudio.io/) and powered by [Tact](https://tact-lang.org/) — the scalable smart contract language for the TON blockchain. Compete with other developers, write efficient on-chain code, and earn both rewards and on-chain reputation.

This contest is your chance to build real-world smart contracts in a battle-tested format. You don’t need to be an expert — everyone is welcome to join and grow through competition.

## 🧩 Challenge Tasks

Participants will complete a series of tasks focused on voting mechanics:

1. **Simple Voting** – basic voting logic
2. **Serial Voting** – multiple proposals under a single master contract
3. **Scalable Voting** – support for up to 4 billion voters
4. **Voting with Refunds** – implement voter refunds
5. **Gas-Managed Voting** – write highly optimized smart contracts

## 🏆 Prize Distribution

- Top **128 participants** share the $20,000 prize pool in Toncoin
- All participants who submit at least one valid solution will receive a **Participant SBT**
- SBTs will store **on-chain developer reputation**, reflecting your performance and participation
- Top performers will be **invited for job interviews** at TON Studio

## 🔥 Why Join?

- 💡 Learn to write scalable and gas-optimized smart contracts
- 🏅 Gain on-chain credentials via SBTs
- 🤝 Get visibility and potential job opportunities
- 🚀 Compete and grow in a global smart contract developer community

## What is Codeforces?

## What is TON Nest?

Nest is a cozy community exclusively for builders that offers access to private, community-gated workshops and a chance to participate in a leaderboard to compete for rewards (Open League simulator for the youngestyounest).

Are you an early builder seeking mentorship, advice, and support on your challenging journey to achieving initial traction? TON Nest is designed to connect three vital aspects:
- **Mentorship support:** Throughout all the steps, you will have access to mentors in the chats who have already launched their apps, built communities, and crafted viable businesses.
- **Marketing support:** Once your project is launched, we will organize AMAs, live streams, and digests featuring your app to boost your visibility.
- **Cash rewards:** The top projects pitched within the program will receive cash rewards.

## What is the actual process?
To join the program, every project must first pitch. However, if you’ve participated in our hackathon, you have a shortcut—hackathon participants are automatically in!

After you successfully pitch and receive a link to join the initial chat (yes, there are a couple!), you can claim your SBT and start engaging with the activities.

Looking to jumpstart your journey with comprehensive support and rewards? Don’t miss this chance to elevate your project with TON Nest!
