evmOS - A plug-and-play solution that adds EVM compatibility and customizability to your chain

What is evmOS?

evmOS is a plug-and-play solution that adds EVM compatibility and customizability to your chain! Becoming an evmOS partner, you will get:

  • Full access to evmOS modules and updates
  • Smooth onboarding experience for an existing or new Cosmos chain
  • Full access to product partnerships (block explorers, RPCs, indexers etc.)
  • Continuous upgrades, access to product and engineering support

evmOS is production ready, and suitable for usage in mission-critical environments such as application-specific EVMs.

Plug-in evmOS into your chain

Integration

evmOS can easily be integrated into your existing chain or added during the development of your upcoming chain launch by importing evmOS as a go module library. The evmOS team provides you with integration guides and core protocol support depending on your needs and configurations. Please check below how to become an evmOS partner.

Configurations

Our solution is engineered to provide unique flexibility, empowering you to tailor every aspect of your Ethereum Virtual Machine (EVM) environment. Whether you're launching a new blockchain or optimizing an existing one, evmOS offers a suite of features designed to meet the unique demands of your project.

Powerful defaults

evmOS’ modules come out of the box with defaults that will get you up and running instantly.

When integrating all available modules you will get a permissionless EVM-enabled blockchain that exposes JSON-RPC endpoints for connectivity with all EVM tooling like wallets (MetaMask, Rabby, and others) or block explorers (Blockscout and others). You will have access to all of evmOS’ EVM extensions, which enable access to chain-native functionality through Solidity smart contracts. Your chain provides a seamless use of any IBC asset in the EVM without liquidity fragmentation between wrapped and unwrapped tokens. Transaction surges are handled by the self-regulating fee market mechanism based on EIP-1559 and EIP-712 allows for structured data signing for arbitrary messages.

Did we mention? Everything can be controlled by on-chain governance to create alignment between chain teams and their communities.

Extensive customizations

Based on these powerful defaults, the feature set is easily and highly customizable:

  • Permissioned/Restricted EVM

    Maintain control over your network with permissioned or restricted EVM capabilities. Implement customized access controls to either blacklist or whitelist individual addresses for calling and/or creating smart contracts on the network. Read more on EVM access control here.

  • EVM Extensions

    Extend the capabilities of your EVM! These EVM extensions allow functionality that is native to Cosmos SDK modules to be accessible from Solidity smart contracts. We provide a selection of plug-and-play EVM extensions that are ready to be used today.

    Push the boundaries of what’s possible with fully custom EVM extensions. Develop the business logic that sets your chain apart from others with the mature tooling for the Go language and offer its functionality to the masses of Solidity smart contract developers to integrate in their dApps.

  • Single Token Representation v2 & ERC-20 Module

    Simplify token management with Single Token Representation v2 and our x/erc20 module to elevate the user experience on your chain. Align IBC coins and ERC-20s and say goodbye to fragmented liquidity. One balance. In every tool.

  • EIP-1559 Fee Market Mechanism

    Take control of transaction costs with our ready-to-use EIP-1559 fee market solution. Tailor fee structures to suit your network’s specific needs, balancing user affordability with network sustainability. Or disable it altogether.

  • JSON-RPC Server

    There is full control over the exposed namespaces and fine-grained control of the JSON-RPC server. Adjust the configuration to your liking, including custom timeouts for EVM calls or HTTP requests, maximum block gas, the number of maximum open connections, and more.

  • EIP-712 Signing

    You have the option to integrate our EIP-712 signature implementation, which allows Cosmos SDK messages to be signed with EVM wallets like MetaMask.

  • Custom Improvement Proposals (Opcodes)

    Any evmOS partner is provided the opportunity to customize bits of their EVM opcodes and add new ones. Read more on custom operations here.

Forward-compatibility with Ethereum

Ethereum-equivalence describes any EVM solution, that is identical in transaction execution to the Ethereum client. It does not more, but also not less than that.
Ethereum-compatible means, that the EVM can be set up to run every transaction that is valid on Ethereum, while the handling of the transactions can diverge in e.g. result or cost.

We like to coin the term forward-compatible as a description of our EVM solution, meaning that any evmOS chain can run any valid smart contract from Ethereum but can also implement new features that are not (yet) available on the standard Ethereum VM, thus moving the standard forward.

Roadmap

Our near-term roadmap looks like this:

2024 Q3 - v1

  • Cosmos SDK v0.50 support

2024 Q4 - v2

  • Proof of Authority
  • ADR-008
  • Support for modular Blockchains - integrate with Rollchain

Of course, we are always open to collaborate with our partners in case of mutual interests for other features.

How to become an evmOS partner?

evmOS operates under a Non-Commercial License, ensuring our partnerships are focused on building successful business cases that contribute to the long-term success of both evmOS and your project. Our team, consisting of the creators of Ethermint and seasoned experts in Cosmos and EVM, is ready to assist with technical onboarding, support, and go-to-market strategies.

If you're interested in integrating evmOS into your stack and exploring a partnership, please reach out to discuss your product and technical requirements. We look forward to collaborating with you on this journey.
