## What it is
Polaris is a modular Go framework for embedding the Ethereum Virtual Machine (EVM) into arbitrary applications or consensus engines, including the Cosmos-SDK. The project is officially deprecated and no longer maintained.

## Use cases
- embed an EVM execution environment into a Cosmos-SDK chain
- build a custom blockchain with Ethereum smart contract support
- integrate EVM into a custom consensus engine
- run Ethereum-compatible smart contracts in a Go application
- experiment with modular EVM components like state or gas handling

## When to choose
- you need a modular, embeddable EVM in Go and are willing to maintain it yourself
- you want to study how an EVM can be integrated with Cosmos-SDK

## When to avoid
- you need a maintained, production-ready EVM implementation
- you want community support or regular updates
- you are building a new chain today - consider actively maintained alternatives

## Facets
- artifact type: framework
- maturity: abandoned
- function: blockchain, interpreter, sdk, developer-tools
- domain: blockchain, developer-tools
- platform: go, cross-platform
- tags: evm, cosmos-sdk, smart-contracts, web3, deprecated, cryptocurrency
