## Token standards
<br>
* ERC stands for Ethereum request for comments.
* These are technical documents written by Ethereum developers for Ethereum community.
* Each such document contains a set of rules required to implement tokens for the Ethereum ecosystem.
* You can say ERC is a specific type of EIP.
