# TAC

## The Challenge: Bridging Deployment to Adoption

TAC revolutionizes the deployment of EVM protocols on TON by eliminating the need to rewrite smart contracts or learn TON’s TVM architecture and languages such as FunC, Tact, or Tolk. This breakthrough enables EVM developers to seamlessly tap into Telegram’s 1 billion users, significantly lowering technical barriers.

However, a critical gap remains between *deployment* and *adoption*: **how to effectively connect these protocols with Telegram users.**

Despite Telegram’s massive user base, EVM protocols must still develop Telegram Mini Apps, redesign interaction flows, and create user experiences tailored to Telegram’s audience. This imposes substantial development costs and diverts focus from protocol innovation. For Telegram users, navigating multiple protocol-specific Mini Apps creates a fragmented and complex experience, hindering the transition from Web2 to Web3.

## The Solution: tgUSD and Torch Finance

**Telegram USD (tgUSD)**, powered by Torch Finance, is purpose-built for Telegram users and serves as the key to overcoming these challenges. More than just a stablecoin, tgUSD is a seamless conduit that connects Telegram users to TAC’s DeFi ecosystem. It delivers value through:

* **Eliminating User Interface Burdens**\
  TAC removes the need for EVM protocols to rewrite code, while tgUSD removes the need to design Telegram Mini Apps. By providing a unified, Telegram-native Mini App, tgUSD enables users to access TAC’s ecosystem effortlessly, saving protocols significant time and resources.
* **Empowering Protocols to Focus on Yield Creation**\
  With tgUSD handling user onboarding, EVM protocols can concentrate on their core strengths: optimizing capital efficiency, designing high-yield strategies, and enhancing performance. User funds flow through tgUSD into TAC’s ecosystem, allocated to protocols like Morpho, creating a virtuous cycle of liquidity and value creation.
* **Delivering a Simple, Consistent User Experience**\
  The tgUSD Mini App, designed in Telegram’s familiar style, allows users to deposit assets, stake, and earn yields without needing to understand complex DeFi protocols or switch between multiple apps. tgUSD encapsulates cross-chain and DeFi complexities, presenting users with a streamlined experience akin to a “stablecoin savings account” within Telegram.

## TAC + tgUSD: A Complete Ecosystem Flywheel

**TAC solves the deployment challenge; tgUSD solves the adoption challenge.**

Together, they eliminate all barriers between EVM protocols and Telegram users, activating TAC’s envisioned flywheel effect:

* **EVM Protocols**: Focus on innovating and creating high-yield strategies.
* **Telegram Users**: Participate in DeFi with minimal barriers and an intuitive experience.
* **On-Chain Liquidity**: Remains stable, circulates efficiently, and builds a long-term economic moat.

## Conclusion

tgUSD is more than a stablecoin—it’s a vital conduit that channels Telegram users’ funds, engagement, and liquidity into TAC’s ecosystem. By ensuring protocols are not just deployed but widely used, tgUSD empowers EVM protocols to thrive on TON, transforming TAC’s vision into a user-driven reality.

## 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://doc.torch.finance/telegram-usd/how-tgusd-works/use-cases/cross-chain-expansion/tac.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.
