## What it is
Solady is a collection of gas-optimized Solidity smart contract snippets and libraries for Ethereum development. It provides implementations of popular token standards (ERC20, ERC721, ERC1155), authorization mixins, account abstraction contracts, and utility libraries.

## Use cases
- deploy gas-efficient ERC20 tokens
- implement ERC721 NFT contracts with minimal gas costs
- add ownership and role-based access control to smart contracts
- build ERC4337 account abstraction wallets
- use utility libraries like Base64, ECDSA, and EIP712 in Solidity
- deploy deterministic contracts with CREATE3
- implement ERC4626 tokenized vaults

## When to choose
- you want battle-tested, gas-optimized Solidity implementations of common standards
- you prefer copy-paste snippets over inheriting from a large framework like OpenZeppelin
- you need account abstraction (ERC4337, ERC6551, EIP7702) building blocks
- you want minimal dependencies and inline-assembly-optimized code

## When to avoid
- you need a full audited framework with extensive upgradeability tooling
- you require formal verification guarantees or insurance-backed contracts
- you are not developing for EVM-compatible chains
