  Yield Protocol is a decentralized (Ethereum smart-contract) protocol, now
  closed. It ships no REST/HTTP client SDKs; its first-party developer packages
  are Solidity contract/interface libraries published to npm under the official
  @yield-protocol scope, consumed by developers integrating with the on-chain
  protocol. All packages below were verified live in the npm registry.
