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
