Registry Contract

This is a Solidity smart contract that allows users to set their name by sending 1 unit of a specified ERC20 token.

Usage

Deploying the Contract

To deploy the contract, you will need to provide the address of the ERC20 token contract that you want to use as the required token. You can do this by passing the address as an argument to the constructor when you deploy the contract.

Setting a Name

To set a name, a user needs to call the set function and provide the desired name as a string argument. In addition, the user needs to send 1 unit of the required token to the contract.

Viewing a Name

To view the name associated with an address, you can call the names function with the address as an argument.
