Import to Remix

To begin, navigate to remix and import this gist.

import gist

This gist will result in three files being imported into your remix IDE.

Let's take a look at the files first.

  • CT Helpers is a library, which implements helper routines for the conditional tokens contracts. We won't be going too much into detail about the implementations done here, but this is required by the conditional tokens contract.
  • The conditional tokens contract here is actually adapted from the canonical version to use Open Zeppelins new ERC1155 implementation, so it actually differs a little from the canonical version.
  • Finally, the gist contains a tutorial.sol source file. This source file imports the conditional tokens contract as well as an ERC20 based contract from Open Zeppelin. This base contract is used to implement a toy token that can be minted by any address and is used to illustrate how ERC20 tokens interact with the conditional tokens contracts.

Once you have imported the gist, go to the "solidity compiler" module and compile tutorial.sol using any solidity 0.6 compiler.

Then go to the "deploy and run" module and deploy tutorial.sol to your preferred network.

The canonical addresses for the contracts on some existing networks:

  • Rinkeby: 0x36bede640D19981A82090519bC1626249984c908
  • Mainnet: 0xC59b0e4De5F1248C1140964E0fF287B192407E0C

Deploy ERC20 Tokens

Let's begin by creating a couple of ERC20 toy tokens to illustrate how different ERC20 tokens can be used with the same conditional tokens contracts.

In the "deploy and run" module, deploy two instances of the ToyToken. You can give them any name and symbol you like, just make them unqique so that we can reference them later.

deploy ToyToken

Deploy Conditional Tokens contracts

Now deploy an instance of the conditional tokens contract (you may need to increase the gas limit to ~6,500,000 or more), or load it from a previously deployed address if you have already deployed it on your selected network previously.

The bottom of "deploy and run" module should look something like this:

deploy Conditional Token Contract

Next we'll learn how to create a condition.
