## Health v2 (maintenance only)
Score: 93/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 80, longevity 100
- inputs: {"age_days": 4034, "days_push": 7, "days_rel": 55, "gap_med": 61, "n_releases_24m": 10}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Solidity is a statically-typed, contract-oriented high-level programming language for writing smart contracts that run on the Ethereum Virtual Machine. The repository contains the reference compiler (solc), also available as a JavaScript build (solc-js) via npm.

## Use cases
- write smart contracts for ethereum
- compile solidity to evm bytecode
- create erc-20 tokens
- build decentralized applications
- implement voting or auction contracts
- develop multi-signature wallets

## When to choose
- you are developing smart contracts for Ethereum or EVM-compatible chains
- you need the official, up-to-date Solidity compiler with the latest features and security fixes
- you want a mature language with extensive documentation and community tooling like Remix

## When to avoid
- you target non-EVM blockchains such as Solana or Move-based chains
- you need long-term compiler stability, since 0.x versioning means regular breaking changes
- you only need to audit or analyze existing contracts rather than write and compile new ones

## Facets
- artifact type: cli-tool
