## README

Ethereum ABI Coder
==================

This sub-module is part of the [ethers project](https://github.com/ethers-io/ethers.js).

It is responsible for encoding and decoding the Application Binary Interface (ABI)
used by most smart contracts to interoperate between other smart contracts and clients.

For more information, see the [documentation](https://docs.ethers.io/v5/api/utils/abi/).

Importing
