Architecture
EVM Compatibility
Full EVM compatibility with all opcodes and precompiles
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:
- Update RPC endpoint to MANTRA Chain
- Update chain ID to
5888(mainnet) or5887(testnet) - Deploy contracts using your existing deployment scripts
- 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.
