+
+## 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)
+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](https://metamask.io/), [Rabby](https://rabby.io/), and others)
+or block explorers ([Blockscout](https://docs.blockscout.com/) and others).
+You will have access to *all of evmOS’ EVM extensions*,
+which enable access to chain-native functionality
+through [Solidity](https://docs.soliditylang.org/en/v0.8.26/) 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](https://docs.evmos.org/protocol/modules/evm#access-control).
+
+- *EVM Extensions*
+
+    Extend the capabilities of your EVM!
+    These [EVM extensions](https://docs.evmos.org/develop/smart-contracts/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](https://medium.com/evmos/evmos-introduces-native-tokens-as-erc-20-for-cosmos-1a4c7de5c3e9)
+    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](https://eips.ethereum.org/EIPS/eip-1559) 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](https://docs.evmos.org/develop/api/ethereum-json-rpc).
+    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](https://eips.ethereum.org/EIPS/eip-712) 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](https://docs.evmos.org/develop/smart-contracts/custom-improvement-proposals).
+
+### 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.
+
