What is TAC Protocol (TAC)?

Deep Dive

1. Purpose & Value Proposition

TAC solves TON’s lack of native Ethereum Virtual Machine (EVM) compatibility, enabling Ethereum developers to port dApps directly into Telegram’s ecosystem without rewriting code (TAC Protocol FAQ). By acting as a cross-chain adapter, it allows TON users to interact with EVM dApps (e.g., DeFi, gaming) through their existing TON wallets, bypassing fragmented liquidity or fragmented user experiences.

The protocol targets Telegram’s billion-user base, offering a ready-made distribution channel for dApps. This eliminates the need to bootstrap new users, a critical hurdle for most blockchains.

2. Technology & Architecture

Built on CosmosEVM (evmOS), TAC combines Ethereum’s Cancun-upgrade compatibility with a Tendermint-based DPoS consensus, achieving ~2-second block finality. Key innovations:
- TON Adapter: Facilitates cross-chain communication, letting EVM logic run on TAC while frontends operate on TON.
- Hybrid Security: Integrates Babylon’s Bitcoin staking to secure consensus, requiring validators to bond both $TAC and BTC (Blockworks).

This architecture ensures developers retain Ethereum tooling (Solidity, Chainlink) while accessing TON’s user base.

3. Tokenomics & Governance

$TAC serves three primary roles:
- Gas Fees: All TON-denominated transaction fees are converted to $TAC via backend logic, creating constant buy pressure.
- Staking: Validators bond $TAC to participate in DPoS, offering 8–10% annualized yields to delegators.
- Governance: Holders vote on protocol upgrades, liquidity incentives, and treasury management.

The token’s utility is tightly linked to network usage, with a 5% annual inflation rate and 60% target staking ratio.

Conclusion

TAC Protocol is a strategic bridge between Ethereum’s developer ecosystem and Telegram’s massive user base, combining EVM flexibility with TON’s distribution reach. Its success hinges on adoption by Ethereum-native dApps seeking frictionless access to Telegram’s audience.

What’s next? Can TAC sustain liquidity incentives and developer engagement as competition within the TON ecosystem intensifies?
