Overview

Understanding how the EVM module provides Ethereum compatibility within the Ontomir SDK platform

The Ontomir EVM module implements a complete Ethereum Virtual Machine as a Ontomir SDK module, providing an Ethereum-compatible interface to the underlying Ontomir consensus and infrastructure while enabling access to the broader Ontomir ecosystem.

Platform Integration

The EVM module sits atop the Ontomir SDK platform, leveraging its modular architecture:

  • Consensus Layer: CometBFT provides Byzantine fault-tolerant consensus with instant finality

  • State Management: Ontomir SDK's IAVL tree and KVStore handle state persistence

  • Account System: Unified account model supporting both Ethereum and Ontomir address formats

  • Module Ecosystem: Direct access to staking, governance, bank, and IBC modules through precompiles

Ethereum Compatibility

The EVM module provides complete Ethereum compatibility, enabling all standard Ethereum tooling and workflows:

  • Smart Contracts: Full EVM bytecode execution with identical gas costs and opcode behavior

  • Transaction Types: Support for all Ethereum transaction formats including EIP-1559 and EIP-7702

  • JSON-RPC API: Complete Ethereum RPC implementation for seamless tool integration

  • Development Tools: Works with MetaMask, Hardhat, Foundry, Remix, and all Ethereum development frameworks

Enhanced Features

Ontomir SDK Benefits

  • Instant Finality: Transactions are final after one block (~2 seconds) with no reorganizations

  • Cross-Chain Integration: Native IBC support for interacting with other Ontomir chains

  • Modular Access: Smart contracts can directly interact with staking, governance, and other Ontomir modules

  • Enhanced Security: Byzantine fault-tolerant consensus with stake-based validator selection

Key Differences from Standard Ethereum

  • Consensus: CometBFT instead of proof-of-stake, providing instant finality

  • State Storage: IAVL tree and Ontomir SDK KVStore instead of Merkle Patricia Tree

  • Fee Distribution: Base fees distributed to validators instead of burned

  • Cross-Chain: Native IBC integration for seamless interchain operations

  • Module Access: Smart contracts can directly call Ontomir SDK modules

Developer Experience

Developers can build on Ontomir EVM using familiar Ethereum tools and patterns:

  • Standard Tooling: MetaMask, Hardhat, Foundry, Remix work without modification

  • Ethereum Libraries: Web3.js, Ethers.js, and other libraries work seamlessly

  • Smart Contracts: Deploy existing Ethereum contracts without changes

  • Enhanced Capabilities: Access Ontomir modules and IBC through precompiled contracts
