**TON Architectural Chain (TAC)** is a [blockchain](https://iq.wiki/wiki/blockchain) infrastructure project that connects [Ethereum](https://iq.wiki/wiki/ethereum)-compatible applications to the [TON](https://iq.wiki/wiki/the-open-network-toncoin) and Telegram ecosystems via an [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible [Layer 1](https://iq.wiki/wiki/layer-1) network and a cross-chain communication framework. The project enables Solidity-based applications to interact with [TON](https://iq.wiki/wiki/the-open-network-toncoin) wallets, assets, and Telegram Mini Apps without requiring developers to rebuild applications for [TON](https://iq.wiki/wiki/the-open-network-toncoin).

## Overview

TAC is an [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible [Layer 1](https://iq.wiki/wiki/layer-1) [blockchain](https://iq.wiki/wiki/blockchain) designed to connect [Ethereum](https://iq.wiki/wiki/ethereum)-based [decentralized applications](https://iq.wiki/wiki/decentralized-application) with the [TON](https://iq.wiki/wiki/the-open-network-toncoin) and Telegram ecosystems. Built on [Cosmos SDK](https://iq.wiki/wiki/cosmos) and Ethermint, it enables developers to deploy Solidity [smart contracts](https://iq.wiki/wiki/smart-contract) and provides interoperability with [TON](https://iq.wiki/wiki/the-open-network-toncoin) via a dedicated cross-chain messaging layer. Its architecture includes the TAC [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) Layer, the [TON](https://iq.wiki/wiki/the-open-network-toncoin) Adapter, and the TAC SDK, which together allow applications to interact with [TON](https://iq.wiki/wiki/the-open-network-toncoin) wallets, [TON](https://iq.wiki/wiki/the-open-network-toncoin)-native assets, and Telegram-based interfaces.

A core feature of TAC is its Hybrid dApp framework, which enables [Ethereum](https://iq.wiki/wiki/ethereum)-compatible applications to be accessed by [TON](https://iq.wiki/wiki/the-open-network-toncoin) users without requiring separate wallets, wrapped assets, or direct interaction with bridging infrastructure. Through development tools and support for Telegram Mini Apps, TAC provides a way for developers to integrate [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-based functionality, including [decentralized finance](https://iq.wiki/wiki/defi) services such as asset swaps, lending, and yield-generating applications, into the [TON](https://iq.wiki/wiki/the-open-network-toncoin) and Telegram ecosystems.

## Features

### Hybrid dApps

Hybrid dApps are [decentralized applications](https://iq.wiki/wiki/decentralized-application) that combine [Ethereum](https://iq.wiki/wiki/ethereum)-compatible [smart contract](https://iq.wiki/wiki/smart-contract) functionality with user interfaces and distribution channels built within the [TON](https://iq.wiki/wiki/the-open-network-toncoin) and Telegram ecosystems. Using TAC’s infrastructure, developers can deploy existing Solidity-based applications, enabling users to access them through [TON](https://iq.wiki/wiki/the-open-network-toncoin) wallets and Telegram Mini Apps. The underlying smart contract logic executes on TAC’s [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible [Layer 1](https://iq.wiki/wiki/layer-1), while cross-chain communication is handled through the [TON](https://iq.wiki/wiki/the-open-network-toncoin) Adapter.

The Hybrid dApp model is designed to connect Ethereum-based decentralized finance and application infrastructure with Telegram-native user experiences. Through the TAC SDK, Telegram Mini Apps can interact with [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) [smart contracts](https://iq.wiki/wiki/smart-contract) without requiring users to manage multiple wallets, switch networks, or use bridging mechanisms. This architecture enables applications such as token swaps, lending protocols, liquidity provision platforms, and other [blockchain](https://iq.wiki/wiki/blockchain) services to be accessed through familiar Telegram interfaces while leveraging TAC's security and execution environment. Examples of applications integrated through this framework include [decentralized finance](https://iq.wiki/wiki/defi) protocols such as [Curve](https://iq.wiki/wiki/curve-finance), [Morpho](https://iq.wiki/wiki/morpho), and [Euler](https://iq.wiki/wiki/euler-ai). Hybrid dApps also provide a pathway for interoperability between the [TON](https://iq.wiki/wiki/the-open-network-toncoin) ecosystem and [Ethereum](https://iq.wiki/wiki/ethereum)-based applications, allowing [TON](https://iq.wiki/wiki/the-open-network-toncoin) users to access [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) functionality while enabling Solidity developers to deploy applications without rebuilding them for [TON](https://iq.wiki/wiki/the-open-network-toncoin)’s native virtual machine.

## Architecture

TAC is a [Layer 1](https://iq.wiki/wiki/layer-1) [blockchain](https://iq.wiki/wiki/blockchain) architecture designed to enable interoperability between the [TON](https://iq.wiki/wiki/the-open-network-toncoin) ecosystem and [Ethereum](https://iq.wiki/wiki/ethereum)-compatible [smart contracts](https://iq.wiki/wiki/smart-contract). The protocol combines an [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible execution layer with a cross-chain communication framework that facilitates deterministic message passing and asset transfers between [TON](https://iq.wiki/wiki/the-open-network-toncoin) and TAC. Its architecture relies on standardized cross-chain messaging, decentralized sequencing, and on-chain verification to coordinate interactions across both networks while maintaining native user experiences on the [TON](https://iq.wiki/wiki/the-open-network-toncoin) side.

The architecture consists of several core components. The TAC [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) Layer, built with [Cosmos SDK](https://iq.wiki/wiki/cosmos) and Ethermint, provides a fully [Ethereum](https://iq.wiki/wiki/ethereum)-compatible execution environment that supports Solidity [smart contracts](https://iq.wiki/wiki/smart-contract), standard [Ethereum](https://iq.wiki/wiki/ethereum) development tools, EIP-1559 [gas](https://iq.wiki/wiki/gas) mechanics, and [delegated proof-of-stake](https://iq.wiki/wiki/delegated-proof-of-stake-dpos) consensus. Cross-chain communication is managed through the [TON](https://iq.wiki/wiki/the-open-network-toncoin) Adapter, a set of [smart contracts](https://iq.wiki/wiki/smart-contract) deployed on both networks that validate transactions, lock and manage assets, format messages, verify proofs, and prevent duplicate or invalid executions. A decentralized Sequencer Network monitors events across [TON](https://iq.wiki/wiki/the-open-network-toncoin) and TAC, aggregates them into Merkle trees, and submits transaction roots for consensus, while an Execution Layer assigns executors to process validated cross-chain messages and complete operations in a permissionless manner.

Applications integrated with TAC use a combination of the TAC SDK and standardized [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) proxy contracts. The SDK handles message construction and interaction with cross-chain infrastructure on [TON](https://iq.wiki/wiki/the-open-network-toncoin), while proxy contracts on the TAC side receive validated messages and execute the corresponding [smart contract](https://iq.wiki/wiki/smart-contract) calls. Together, these components provide a framework for deploying Hybrid dApps that allow [TON](https://iq.wiki/wiki/the-open-network-toncoin) users to interact with [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-based applications through cross-chain messaging and asset management mechanisms.

## Tokenonmics

TAC is the native [utility token](https://iq.wiki/wiki/utility-token) of the TAC Network and serves as the primary asset for transaction processing, network security, and governance. Issued as an [ERC-20](https://iq.wiki/wiki/erc-20) token on the TAC [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) Layer, it is integrated into the protocol’s execution and [consensus mechanisms](https://iq.wiki/wiki/consensus-mechanism) and is used across the network’s core infrastructure. Within the protocol, TAC functions as the [gas](https://iq.wiki/wiki/gas) token for transactions executed on the TAC [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) Layer. It is also used in the network’s [delegated proof-of-stake](https://iq.wiki/wiki/delegated-proof-of-stake-dpos) system, where [validators](https://iq.wiki/wiki/validator) stake tokens to help secure the [blockchain](https://iq.wiki/wiki/blockchain) and may face penalties for malicious behavior. In addition, staked TAC provides governance rights, allowing participants to vote on protocol upgrades, network parameters, and other ecosystem decisions. For users interacting through [TON](https://iq.wiki/wiki/the-open-network-toncoin), the network can automatically convert [transaction fees](https://iq.wiki/wiki/transaction-fee) into TAC, allowing cross-chain operations to be processed without direct management of the token.
