## What it is
Alloy is a high-performance Rust library for connecting applications to Ethereum and EVM-based blockchains, providing transports, providers, middleware, signers, and network abstractions. It is a ground-up rewrite of ethers-rs featuring the sol! macro for contract bindings, multicall support, and a composable provider architecture.

## Use cases
- connect to an ethereum node from rust
- send transactions on evm chains
- read smart contract state in rust
- interact with erc20 tokens programmatically
- build a rust web3 backend
- query blockchain data via rpc
- sign and broadcast ethereum transactions
- support multiple evm networks in one app

## When to choose
- you are building a Rust application that talks to Ethereum or any EVM chain
- you want a modern, actively maintained replacement for ethers-rs
- you need high-performance ABI encoding and U256 primitives
- you want composable providers with middleware layers and multicall support

## When to avoid
- your project is in another language like JavaScript, Python, or Go
- you need non-EVM blockchains like Bitcoin or Solana
- you only need a quick one-off script where a CLI tool suffices

## Facets
- artifact type: library
- maturity: active
- function: database-driver, rpc, middleware, sdk, serialization
- domain: blockchain, developer-tools, apis
- platform: rust, cross-platform
- tags: ethereum, evm, web3, smart-contracts, blockchain-rpc, signers, transports, ethers-rs-successor, cryptocurrency
