Description

A simple contract allows to lend some amount of particular ERC20 token (impl by https://github.com/paritytech/pwasm-token-example) for some interest. It demonstrates how WASM contracts can depend on each other and communicate through ABI. It shows also how to mock callee contract in the test environment.
