# Redeem Protocol v2

The Redeem Protocol v2 contains receiving `ERC20` functions to let customers can charge fees when holders redeem their NFTs.

We provide two smart contracts - RedeemProtocolFactory and RedeemProtocolRealm. The `Factory` can create a `Realm` and set all the fees of the `Realm`.

## [RedeemProtocolFactory](https://github.com/redeemprotocol/RedeemProtocol-Contracts/blob/master/EVM/contracts/RedeemProtocolFactory.sol)

### Rules

#### ADMIN

`ADMIN` can pause the `Reverse` and set the receiver's address to earn charging of redeeming.

#### OPERATOR

`OPERATOR` can set all of the fees in `Reverse`.

#### ROOT\_CREATOR, REVERSE\_CREATOR

`ROOT_CREATOR` and `REVERSE_CREATOR` can create the reverse.
