SummaryCreate Conditional Tokens Positions on Gnosis Chain using Scaffold-Eth 2. This document uses the Gnosis documentation “Introduction - Gnosis Developer Portal Conditional Tokens” as its source and will cover a limited Scope of the tutorial.Gnosis Developer Portal Conditional Tokens Tutorialhttps://docs.gnosis.io/conditionaltokens/docs/ctftutorial01/Scaffold-Eth 2https://scaffoldeth.io/ScopeRepositories and ModificationsDeploy Conditional and Collateral Token ContractsMint and Approve Collateral TokensConditional Token PreparationCreating Positions with Conditional TokensRepositories and ModificationsThe contract code was copied from the Gist repository in the gnosis tutorial and modified to support integration into scaffold-eth.Reference: Gnosis Developer Gist Repositoryhttps://gist.github.com/cag/65dc3ddfa03f067dd41ca7121ee3120fIn Use: Gnostic Condition Scaffold Eth Repositorygnostic-condition branch on OwlWilderness/se-2 repository This is the working repository for code in this demo. https://github.com/OwlWilderness/se-2/tree/gnostic-conditionConditional Token ContractThe import format was modified to use @Openzepplin instead of a github reference in all files. SafeMath was included for uint in the Conditional Tokens contract. https://github.com/OwlWilderness/se-2/blob/gnostic-condition/packages/hardhat/contracts/ConditionalTokens.sol//SPDX-License-Identifier: MIT pragma solidity >=0.8.0 <0.9.0; import { SafeMath } from "@openzeppelin/contracts/utils/math/SafeMath.sol"; import { IERC20 } from "@openzeppelin/contracts/token/ERC20/IERC20.sol"; import { ERC1155 } from "@openzeppelin/contracts/token/ERC1155/ERC1155.sol"; import { CTHelpers } from "./CTHelpers.sol"; // Mainnet (ID: 1) canonical address: 0xC59b0e4De5F1248C1140964E0fF287B192407E0C // Rinkeby (ID: 4) canonical address: 0x36bede640D19981A82090519bC1626249984c908 contract ConditionalTokens is ERC1155 { using SafeMath for uint; ...

Two contracts are created and deployed in scaffold-eth as the deployed contract object uses the name of the contract as the key. **without doing this OOB the debug contract page will only show for one of the collateral tokens https://github.com/OwlWilderness/se-2/blob/gnostic-condition/packages/hardhat/contracts/GnosticTokens.sol//SPDX-License-Identifier: MIT pragma solidity >=0.8.0 <0.9.0; import { ConditionalTokens } from "./ConditionalTokens.sol"; import { ERC20 } from "@openzeppelin/contracts/token/ERC20/ERC20.sol"; contract GnosticToken0 is ERC20 { constructor(string memory name, string memory symbol) ERC20(name, symbol) {} function mint(address account, uint256 amount) external { _mint(account, amount); } } contract GnosticToken1 is ERC20 { constructor(string memory name, string memory symbol) ERC20(name, symbol) {} function mint(address account, uint256 amount) external { _mint(account, amount); } } Deploy Conditional and Collateral Token ContractsFork and Clone gnostic-condition repositoryFork / clone the gnostic-condition repository - reference the below article for instruction. https://mirror.xyz/quantumtekh.eth/jnuL3guybvgeXBFShILuiA53Pq9igs4jFcqYZpSqMNoDeploy Contracts On HardhatFollow instructions in Scaffold-eth 2 ReadMe to Yarn Install, Chain, Start and Deploy to start the hardhat chain local webhostFund Hardhat WalletOpen a new private window and navigate to http://localhost:3000/debug Click the Faucet Icon in the upper right to fund the hardhat wallet.Mint and Approve Collateral TokensCollateral Tokens are used to Mint Conditional Position Tokens.
