## What it is
Evmos is a scalable, high-throughput Proof-of-Stake EVM blockchain built on the Cosmos SDK and CometBFT consensus engine, fully compatible and interoperable with Ethereum. It serves as the canonical EVM chain on Cosmos and the flagship implementation of the evmOS stack for building forward-compatible EVM chains.

## Use cases
- run an EVM-compatible proof-of-stake blockchain node
- deploy and execute Ethereum smart contracts on Cosmos
- bridge assets between Ethereum and Cosmos ecosystems
- build custom EVM chains using the evmOS stack
- interact with the Evmos chain via CLI
- develop interoperable Cosmos and Ethereum applications

## When to choose
- you need an EVM chain with Cosmos SDK interoperability and IBC support
- you want to run or validate on a high-throughput PoS EVM blockchain
- you are building a custom EVM-compatible chain on the evmOS stack

## When to avoid
- you need a simple Ethereum L2 or standalone EVM without Cosmos integration
- you want a chain in a language other than Go
- you need a fully permissionless public chain rather than building your own
