## What it is
An NPM package providing mainnet addresses, ABIs, and Solidity interfaces for popular Ethereum DeFi protocols like Uniswap, AAVE, Compound, and MakerDAO. It includes TypeScript-powered autocomplete and supports importing individual protocols to keep bundle sizes small.

## Use cases
- get ABIs and mainnet addresses for DeFi protocols
- import ERC20 token ABIs and addresses in JavaScript
- use Solidity interfaces for DeFi protocols in smart contracts
- integrate Uniswap or Compound into a dapp quickly
- build a DeFi swap contract with prebuilt interfaces

## When to choose
- you need quick access to ABIs and addresses for major Ethereum DeFi protocols
- you want typed, autocomplete-friendly contract references in TypeScript
- you are prototyping a dapp or smart contract that interacts with DeFi legos

## When to avoid
- you need up-to-date addresses for protocols or chains not covered by the package
- you require L2 or testnet contract addresses
- you need actively maintained ABIs for the latest protocol versions

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, plugin-system
- domain: blockchain, developer-tools, fintech
- platform: -
- tags: ethereum, defi, abi, solidity, smart-contracts, web3, cryptocurrency, nodejs
