Fungible asset is an essential component of any blockchain. The Root Network comes with pre-built pallets asset and assetsExt that make fungible asset management easy and intuitive, highly optimized for efficiency and stable transaction fees. Additionally, fungible assets on The Root Network are ERC-20 compatible, once created they are tradable on both native and EVM layers. The following guide will walk you through how to create, mint, and manage a fungible asset using The Root Network Portal.

​
Requirements

  • Parameters:
    • name: The name of the asset.
    • symbol: The symbol of the asset.
    • decimals: The number of decimals in the asset, max is 18 decimals.

​
Step 3: Confirm asset creation

​
Step 4: Mint asset to account

  1. Go to the Portal Extrinsics page and input the values as per the screenshot below:
  • Extrinsic: assetsExt.mint()
  • Parameters:
    • assetId: The asset ID to mint. The caller must be the owner of the asset.
    • beneficiary: The account to receive the minted tokens.
    • amount: The amount to mint in the smallest unit. If your asset has 6 decimals, to mint 1 million tokens, it will be 1000000000000 (with 12 zeros).

​
Use FuturePass

It’s possible to have your FuturePass account own an asset instead of a standard account. Follow the above steps but wrap all of the extrinsics in the futurepass.proxyExtrinsic, as per the screenshot:

​
Use Asset on EVM

Once the asset is created in Step 2, you can convert your asset ID to an ERC-20 compatible format to use it on the EVM layer. The native asset has the following ERC-20 address convention: 
0xCCCCCCCC[asset-id in hex padded 0 up to 8 chars]000000000000000000000000
For example, if your asset id is 69372, which is 11064 in hex or 00011064 with padded "0" up to 8 characters, your asset ERC-20 address will be: 
0xCCCCCCCC00011064000000000000000000000000
You can verify this by importing the above address to MetaMask, make sure you add The Root Network to MetaMask using the details here.
