Getting Started with EVM Module

MANTRA-Chain/evm is a forked version of cosmos/evm, offering an EVM-compatible framework for Cosmos SDK-based blockchain development. It enables seamless EVM integration into Cosmos chains.

This Ethereum Virtual Machine (EVM) module supports app-chain creation with native interoperability, IBC for ERC20 tokens, and custom extensions/precompiles. Key features include customizable opcodes, EIP-1559 fees, JSON-RPC, and EIP-712 signing. Primarily in Go (91.9%), with Solidity and JS support. Constantly under development and audit, see our Github for latest versioning. Apache 2.0 licensed.

PLEASE NOTE!

The EVM Module on MANTRA Chain is under constant development and audit cycles.

Overview

MANTRA Chain supports smart contracts written in both Rust (via CosmWasm) and Solidity. MANTRA Chain Testnet, DuKong (mantra-dukong-1) is our primary testnet for both of these smart contract languages. It has formally been configured to support both the EVM module and wasmd built for chains based on the Cosmos SDK. For assistance, please reach out to: contact AT mantrachain.io

In the pages following, we will guide you on recommended local environment setup, configuration, and steps to be able to interact with EVM on MANTRA Chain on both testnet (mantra-dukong-1 ) and mainnet (mantra-1 ).
