## What it is
Ethermint is a Cosmos SDK library for launching scalable, interoperable EVM-compatible blockchains with fast-finality Proof-of-Stake consensus on Tendermint Core. It lets developers run Ethereum-style smart contracts within the Cosmos ecosystem.

## Use cases
- launch an EVM-compatible proof-of-stake blockchain
- run Ethereum smart contracts on a Cosmos SDK chain
- build an interoperable chain bridging Ethereum and Cosmos
- deploy a fast-finality EVM chain using Tendermint consensus
- fork a scalable EVM chain with IBC support

## When to choose
- you need an EVM chain integrated with the Cosmos SDK and IBC ecosystem
- you want Ethereum tooling compatibility with fast PoS finality

## When to avoid
- you need active maintenance and support - the repo is explicitly no longer maintained and code migrated to Evmos
- you want a plain Ethereum L1 or L2 without Cosmos SDK integration
- you need a production-ready solution without contacting the team

## Facets
- artifact type: library

- function: blockchain, sdk, rpc
- domain: blockchain, developer-tools
- platform: go, cross-platform
