 In the previous tutorial we studied [the anatomy of an ERC-20 token in Solidity](/developers/tutorials/understand-the-erc-20-token-smart-contract/) on the Ethereum blockchain. In this article we’ll see how we can use a smart contract to interact with a token using the Solidity language.
 
-For this smart contract, we’ll create a really dummy decentralized exchange where a user can trade ether for our newly deployed [ERC-20 token](/developers/docs/standards/tokens/erc-20/).

 For this tutorial we’ll use the code we wrote in the previous tutorial as a base. Our DEX will instantiate an instance of the contract in its constructor and perform the operations of:
