​
Overview

The EVM Module implements the Ethereum Virtual Machine standard for Cosmos SDK-based chains, enabling full EVM compatibility on MANTRA Chain.

​
Key Features

​
Turing-Complete

Any computation possible within gas limits, enabling complex smart contract logic.

​
Bytecode Execution

Uniform contract execution across all EVM-compatible chains, ensuring consistency.

​
Gas Mechanism

  • Prevents abuse through computational limits
  • Adds transaction fees
  • Ensures network security

​
Security and Isolation

Protects the network from malicious code execution through isolated execution environments.

​
Integration with Cosmos SDK

The EVM module integrates seamlessly with Cosmos SDK modules, allowing:
  • Cross-module interactions through precompiles
  • Native token transfers via Bank module
  • Governance participation through Gov module
  • Staking operations through Staking module

​
Architecture

The EVM module sits alongside Cosmos SDK modules, communicating through:
  • Precompiles: Direct Go code execution
  • Message routing: Cosmos SDK message system
  • State management: Shared state between modules
