web3-ethereum-defi is a Python library for DeFi integration and data research, with wrappers for Uniswap, Aave, Chainlink, and USDC on top of web3.py. Python builders import it instead of writing those protocol wrappers themselves.

Request Network is a protocol and JavaScript library for creating, paying, and tracking crypto invoices and payment requests onchain. Builders install the client library to add invoicing to their own application.

AaveKit is Aave's SDK, a TypeScript client and React hooks over the Aave GraphQL API. Builders use it to read markets and user positions and to build supply, borrow, repay and swap transactions without calling the contracts by hand. Aave v3 and v4 are served by separate SDK versions of the same packages (0.x for v3, 4.0 and later for v4).
