_section: What is ethers?
|
|
|
|
|
|
|
|
|
|
The ethers.js library aims to be a complete and compact library for
|
|
|
|
|
interacting with the Ethereum Blockchain and its ecosystem. It was
|
|
|
|
|
originally designed for use with [ethers.io](https://ethers.io/) and
|
|
|
|
|
has since expanded into a much more general-purpose library.
