The TAC EVM Layer is a fully-fledged Layer-1 blockchain environment based on Cosmos SDK technology. It provides a secure and scalable execution environment specifically optimized for Ethereum-compatible smart contracts, allowing existing EVM dApps to be deployed without modifications or code rewrites, achieving ≈2-second finality through dPoS.

​
Technical Foundation

TAC EVM Layer combines proven blockchain technologies to deliver a robust execution environment that feels familiar to Ethereum developers.

​
Core Technology Stack

The latest Cosmos SDK provides the modular blockchain framework that powers TAC EVM Layer. This battle-tested foundation offers built-in modules for staking, governance, and inter-blockchain communication, while allowing custom modules for TAC-specific functionality.
TAC EVM Layer implements native EVM execution directly within the Cosmos SDK framework. This isn’t a compatibility layer or virtual machine running on top of another VM - it’s true EVM execution with modern consensus guarantees.Every Ethereum opcode, gas calculation, and state transition rule works exactly as it does on Ethereum mainnet, ensuring 100% compatibility for existing Solidity contracts.

​
Performance Characteristics

TAC EVM Layer maintains the security guarantees developers expect from a production blockchain.
≈2-second finality through Tendermint consensus mechanism provides deterministic execution and fast block confirmation. Transactions are irreversibly confirmed with minimal latency.No reorganizations are possible due to Tendermint’s BFT consensus model. This eliminates edge cases where transactions might be reversed or reordered after confirmation.

​
Developer Experience

TAC EVM Layer maintains complete compatibility with the Ethereum development ecosystem while providing enhanced debugging and development capabilities.

​
Tool Compatibility

Every tool in the Ethereum ecosystem works seamlessly with TAC EVM Layer:

Development Frameworks

Hardhat, Truffle, Foundry, and Remix work without configuration changes. Deploy scripts, test suites, and build processes transfer directly.

Wallet Integration

MetaMask, WalletConnect, and other Web3 wallets connect by simply adding TAC as a custom network. No special plugins required.

JavaScript Libraries

Web3.js, Ethers.js, and Viem work exactly as they do with Ethereum. Contract ABIs and interaction patterns remain identical.

Infrastructure Tools

Block explorers, indexers, and monitoring tools designed for Ethereum can index TAC EVM Layer with minimal configuration.

​
Gas and Fee Structure

TAC EVM Layer implements familiar gas mechanics with improvements for predictability and efficiency.

​
EIP-1559 Implementation

TAC EVM Layer uses EIP-1559 gas pricing for predictable transaction fees: 
// Gas calculations work exactly like Ethereum
uint256 gasUsed = gasLimit - gasleft();
uint256 effectiveGasPrice = baseFee + min(maxPriorityFee, maxFeePerGas - baseFee);
uint256 totalCost = gasUsed * effectiveGasPrice;
  • Base Fee: Automatically adjusts based on network congestion, providing predictable pricing for users.
  • Priority Fee: Allows users to pay extra for faster inclusion during high-demand periods.
  • Fee Burning: A portion of transaction fees are burned, creating deflationary pressure on TAC tokens.
