Get Started

1. Create an account on SettleMint here
2. Create an Organisation (e.g. Your_Name_Organisation)
3. Create an Application (e.g. Your_Name_Application)
4. Click on Blockchain networks and add a Polygon Testnet network and a node (e.g. Your_Name_Network, Your_Name_Node). Note: choose the smallest resources
5. Click on Storage and add a IPFS (decentralised) storage. Note: choose the smallest resources
6. Click on Private keys and add a Accessible EC DSA P256 key
7. Click on Smart Contracts sets and add a Empty template (e.g. Your_Name_Asset_Tokenisation). Note: choose the smallest resources

Fund your Private key

1. In the SettleMint BPass Platform, head over to Private keys and copy private key
2. Head over to https://faucet.polygon.technology/
3. Under Mumbai Network, paste your private key and click Submit
4. Note down your private key (notes/stickies/etc)

Set up your PolygonScan API key

1. Head over to https://polygonscan.com/ and go to API-KEYs
2. Create your API key and copy it
3. Note down your API key (notes/stickies/etc)

Setting up and Deployment of your Smart Contract

1. In the SettleMint BPass Platform, head over to Smart contract sets
2. Click on your deployed smart contract set and go to the IDE tab and click view in fullscreen mode
3. Copy the template AssetTokenisation.sol found in ./Smart-Contracts and paste it in the IDE's folder ./contracts. Make sure your file name is the same as the contract name, e.g. AssetTokenisation.sol == contract AssetTokenisation ...
4. In the folder ./deploy, open the file named 00_deploy_example.ts and in line 13, change the name of the contract depending on your file name

  await deploy('AssetTokenisation', {
    from: deployer,
    args: [],
    log: true,
  });

5. In the root folder, open the file named hardhat.config.ts and in line 34, change the Solidity version to 0.8.13 and add in your noted down PolygonScan API key

const config: HardhatUserConfig = {
  abiExporter,
  solidity: {
    version: '0.8.13',
    settings: {
      optimizer: {
        enabled: true,
        runs: 200,
      },
      evmVersion: 'istanbul',
    },
  },
  etherscan: {
    apiKey: {
      polygon : 'xxx'
    }
  },
  namedAccounts,
  networks,
};

6. Deploy your Asset Tokenisation smart contract!

pnpm run smartcontract:deploy:reset

7. Note down your deployed smart contract address (notes/stickies/etc)

8. Open the abi folder, go to AssetTokenisation.json and copy the json contents

9. Note down your json contents (notes/stickies/etc)
