What is TAC?

Question

What is TAC?

Accepted Answer

## TLDR
TAC Protocol is an EVM-compatible Layer 1 blockchain built to bridge Ethereum's decentralized finance (DeFi) ecosystem with Telegram's billion-user network and the TON blockchain.

1. **Purpose-built bridge** – It solves TON's lack of native EVM support, allowing developers to deploy Ethereum dApps directly to Telegram's user base.
2. **Hybrid architecture** – It uses a CosmosEVM framework with a Delegated Proof-of-Stake (DPoS) consensus for fast, Ethereum-compatible transactions.
3. **Distribution-ready ecosystem** – It launched with pre-deployed blue-chip DeFi protocols and over $800 million in bootstrapped liquidity.

## Deep Dive
### 1. Purpose & Value Proposition
TAC Protocol exists to solve a critical gap: The Open Network (TON) blockchain, native to Telegram, cannot natively run applications built for the Ethereum Virtual Machine (EVM). This locked Telegram's massive audience out of the established Ethereum DeFi ecosystem. TAC acts as a dedicated bridge, enabling developers to port or build dApps using Solidity (Ethereum's programming language) and distribute them as **Telegram MiniApps**. This grants Telegram's over one billion users seamless access to DeFi, GameFi, and other EVM-based services directly within the messenger ([CoinMarketCap]( https://coinmarketcap.com/currencies/tac-protocol)).

### 2. Technology & Architecture
TAC is built using a **CosmosEVM** architecture, ensuring full compatibility with Ethereum's latest upgrades. It uses a **Tendermint-based Delegated Proof-of-Stake (DPoS)** consensus mechanism, where the native $TAC token is used for staking and securing the network. This design aims for high performance with approximately 2-second block finality. A key innovation is its fee mechanism: users can pay gas fees in TON, which a network-level paymaster automatically converts into $TAC, abstracting complexity for users and creating consistent buy-pressure for the token ([RedStone](https://x.com/redstone_defi/status/1945066243087851574)).

### 3. Ecosystem Fundamentals
The protocol launched its mainnet on July 15, 2025, with a fully-formed DeFi ecosystem from day one to avoid the "cold-start" problem. It featured pre-deployed major protocols like Curve, Morpho, and Euler. Through a liquidity campaign with Turtle Club, it bootstrapped over **$800 million in Total Value Locked (TVL)**. This ready-made environment allows users to interact via their existing TON wallets, positioning TAC as a turnkey DeFi layer for the TON ecosystem ([CryptoBriefing](https://cryptobriefing.com/tac-token-debuts-in-tvl-as-tac-mainnet-goes-live-with-leading-defi-protocols/)).

## Conclusion
Fundamentally, TAC Protocol is an infrastructure catalyst designed to merge Ethereum's developer ecosystem with Telegram's unparalleled distribution network. Will its ready-to-use DeFi layer successfully onboard Telegram's next billion users to decentralized applications?
