​
Is MANTRA Chain Fully EVM Compatible?

Yes. MANTRA Chain has all of the opcodes and precompiles that a developer would expect on any other EVM chain, including:
  • Ethereum
  • Base
  • Polygon
  • Arbitrum
  • And other EVM-compatible chains

​
What This Means

​
Deploy Without Modification

Deploy contracts written for Ethereum without any modifications. Standard Solidity code works as-is.

​
Use Standard Tooling

All standard EVM tooling works out of the box:
  • Hardhat: Full support
  • Foundry: Full support
  • Remix: Full support
  • Web3.js / Ethers.js: Standard libraries work

​
Leverage Existing Libraries

  • OpenZeppelin contracts
  • Standard Solidity libraries
  • Existing EVM frameworks
  • DeFi protocol integrations

​
Standard Gas Mechanics

  • Same gas costs as Ethereum
  • Standard gas estimation
  • Familiar gas optimization patterns

​
Testing Compatibility

All standard EVM opcodes and precompiles are available and behave identically to other EVM chains.

​
Supported Opcodes

All standard EVM opcodes including:
  • Arithmetic operations
  • Logical operations
  • Memory operations
  • Storage operations
  • Control flow
  • And more

​
Supported Precompiles

Standard Ethereum precompiles plus MANTRA-specific Cosmos precompiles:
  • ECRecover
  • SHA256
  • RIPEMD160
  • Identity
  • ModExp
  • BN256Add
  • BN256Mul
  • BN256Pairing
  • Bls12-381
  • Plus Cosmos SDK precompiles (see Cosmos Precompiles)

​
Migration from Other EVM Chains

Migrating from other EVM chains is straightforward:
  1. Update RPC endpoint to MANTRA Chain
  2. Update chain ID to 5888 (mainnet) or 5887 (testnet)
  3. Deploy contracts using your existing deployment scripts
  4. No code changes required

​
Example: Deploying a Standard ERC-20

// Standard ERC-20 contract - works as-is
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyToken is ERC20 {
    constructor() ERC20("MyToken", "MTK") {
        _mint(msg.sender, 1000000 * 10**decimals());
    }
}
This contract works identically on MANTRA Chain as it would on Ethereum, Base, or any other EVM chain.
